Great product

Nice quality fuse holder. I recommend this item because although price is comparable to other brands this one is small and can be mounted easily. I wanted a setup that was of quality and matched and once again NVX had all the items I needed.

Fuse holder NVX XMFH48 for big 3 upgrade

I had been looking for a good fuse holder for my 98 civic performing the big 3 upgrade using 4 gauge wire and on stock 70/75 amp alternator, and decided to get this holder for alternator to battery. I installed it and it worked, as well as a belva 80amp BMANL80 fuses, I used the same size fuse whats stock in the fuse box for the alternator. I used 3M double sided tape for the mount side of holder since it will be mounted on a metal surface, this will help from accidental grounding as well as holding, and used small screws . As for the cover/cap it seems to stay on but might add a zip tie to better hold it. Over all im satisfied with this product and will purchase again from sonic electronix. I recommend this item. Thanks sonic electronix. The shipping was fast. Got it within a few days. A++++

NvX

does the job put it in with a 150 manl and hadn't had any problems what so ever

NVX 4GA.

NVX is a fairly new company, and so far what I've seen they make quality products at a fair price. I bought the NVX 4GA. to do a second run of 4 gauge, the size of the NVX was slightly larger than average 4GA and more flexible. and the the strands were larger and denser. I'm running 1000 watts rms and have no heating or shorting issues at 16 feet.

good thick wire

If it wasn't for this 5 foot piece of wire I never would if been able to hook up my amps and power cap. I got a belva 4 gage amp kit and compared to this nvx wire, well there is no comparison. Nvx 4 gage weighs twice as much and very thick strong wire. True 4 gage.., very good stuff but expensive

GREAT WIRE!!!

Very good Wire I used as a ground for my system. Doesn't break when flexed like other wires and it was easy to work with.
Would recommend to any do-it-yourself audio enthusiasts

It's some good wire, plain and simple

Incredibly flexible and true 4 gauge. Really good wire for the money.

Great Value

Good looking and durable wires, easy to run and greatly boosts the efficiency of the system.

Great product!!

Good quality, true gauge wire!!! Would buy for future installs!

Best wire I have bought

I got this because it looked good and it was every thing that was in the pic. This is some good stuff that NVX has made super flex able and easy to cut. I would recommend this wire to people. This is true gauge wire not like some other stuff out there. The only cons were I could not find one that's how good this wire is. I hope that this will help you on getting this wire.

nice compact professional lookin fuse holder

it takes the nice fuses and isn't any bigger than it needs to be, been in the car for like 2 years now so far so good. about the same quality or better than my old kicker fuse holder but smaller so it doesn't look stupid in the engine bay. it looks great, unlike those chintzy clear plastic glass fuse holders.

Quality product

I would recommend this product to anyone. It is true 4 gauge and the materials used to make it are top notch.

This wire works great!

This wire is good for holding the current it needs to for my system highly recommend it, being that its actual 4 gauge and not fake 4 gauge it helps with light dimming and sound quality a lot!

NVX crushes the competition!

Strong, thick, heavy, durable, quality and flexible... NVX is going to do 2 things... make consumers happy... AND... hurt the competition's feelings! Every NVX product I have purchased is top notch! NVX has definitely accomplished their mission with me! I am more than happy and feel educated with their top quality, cutting edge products! Thanks NVX!

NVX XMFH48

Worked as is should made install easy no complaints good product.

Work as Intended

Straight forward product, if you need em you need em. Crimped wire well and held in place. Definitely large enough for true 4 gauge wire and good quality.

Just what I needed

Quality holder at a great price, works well and made the install a breeze.

By Frank on April 3, 2018 Verified purchase

Install was a breeze

This harness installed very easily in my car. Wires are easy to install and the fuses are very easily swapped. Will definitely purchase these again in the future.

Nice but fragile.

This products size and look is what drew me to it. It will fit nicely in many tight spaces. The durability of the plastic leaves something to be desired i had not even fully inserted my 4guage wire when the terminal box broke free from the plastic housing causing a tiny screw cover to go tumbling down my engine bay. I would recommend a larger/more durable fuze box if planning to install anywhere where the wires going in have to be bent shortly after leaving the box.

This is another great product recommended by the experts at Sonic electronix, great job guys. Great quality wire.

By David on July 28, 2015 Verified purchase

Pretty Good

This wire is pretty nice. The name brand is a good guarantee that you'll get a good product. Very flexible. Pretty thick too. Deffinitely 4 gauge. Supplying my RF 1000 watt amp nicely.

Fuse holder

Works great. Love the options with different gauge wires it allows. Great quality. Highly recommend it.

By Civic98 on June 26, 2022 Verified purchase

As expected

They get the job done, easy to crimp with plier sized crimpers. As expected, they are not as heavy-duty as more expensive ones.

NVX XW4BL20

It have more Current flow to the amp and it give that more power

By james on October 21, 2016 Verified purchase

great value top quality !

My experience with Sonic Electronix has been excellent ! The NVX product line is a fantastic value and the performance rivals products 3 times the cost.
The wire is extremely high quality and a great value.

Good quality

I was having problems with my agu fuses. So I switched my fuse holder 2A Mini ANL. I haven't had a single fuse melt, blow, or crack since I switched to these.

Good fuse

Good quality fuse and a great price. I can't say anything bad about these.

By Anonymous on July 15, 2019 Verified purchase

These were useful

These fuses were useful along with the nvx distribution block

SIZE OBVIOUSLY DONT MATTER

Opened the box and was ready to send it back. But I have it strapped to 2 15 inch CVRS a Hifonics 1100.1 and every where I go they say " DAMN YOU SHOULD ENTER COMPETITIONS" This battery gives my system the power it needs to slam continuosly. I love shopping on sonicelectronix!

Great value and price

These fuses look very well built and durable, I would buy again.

Excelent

This one ok a kine, pretty fast and secure porchase, I will stronglly recommend this seller

Great price

Great Price for this product I used for my 4000 watt mono amp and speakers.

good wire

great wire used to ground my alpine amp worked great

Amazing true AWG wire

There are so many stands on this wire and the oxygen free copper is outta this world. I would definetly recommend this product to everyone. It was a bit hard to cut but its 1/0 so it's reasonable.

Nice price

This a great price for 125 amp fuse you would triple at least with any other brand just for 2 it’s a great value at its price works great as any fuse would.

Kinetik (Hc 600)

This battery work's Very well, and i have it in my trunk for my sound system, it has worked very well for me and no problem's. It works as an extra power supply that pack's a PunCH!...I have it hooked up to my starting batt and grounded in the trunk in my caddy...with a stock alt, (My suggestion is that You need a Capacitor 2 still hold up your amp's....cus you need 2 maintain a voltage otherwise amps wont putt out an accurate power....! This battery does Perform awesome and, it has alot more stamina than a cap. but if you combine both you will have it made and no light dimmedge.! Get this battery for the back and..the Tsunami X15HCAP-40Farad Capacitor, and or the power acoustik PCX-30F...im running both....and it sound's awesome. And run around 13.8 to 14.2

( Get it. You won't be disappointed )

Works great for small amps

Perfect Battery for small 4 channel amps. Reliable and easy to install.

Nice wire!!

Good quality wire!!! Will buy again!!! Nice true gauge wire!! Thanks

fat little fuse bodies

The plastic housing that encases the fuse element is a bit bulky. If you require a sleeker fuse body wetsounds , Tspec, and knu koncepts have a decent selection, but they are easily twice the price as these, and not always available from Sonic.
Aside from their form these fuses are a decent value, and good quality.

By Dylan on November 22, 2022 Verified purchase

Great battery for being so small.

I have this hooked up to starter battery and stock alternator in my trunk. It's powering an Autotek Mean Machine 2000w rms amp. i was having extreme dimming and power issues so i need something to help out.
So i bought this along with a Power Acoustik 30 farad Cap to maintain constant voltage. All is fixed!! No more dimming and when turned up with the car on i never go below 12.5v.

if you have a stock alternator you need to give your system a break. Don't be blasting all the time because the alternator can't charge the batteries and provide the power all once!

Excellent value!

Look great. Easy to crimp and it really locks onto the cable and the price was right. Item was in stock when I ordered and delivered quickly.

By Jeff on December 7, 2023 Verified purchase

Great value

Recommend this product for the size and value. Very compact

amazing!

don't be fooled by its size!! its very powerful I have it hooked up to my 4000 watt power acoustik mono amp and 2 12in alpine type R's at 1ohm...and it straight POUNDS!!!! $100 is great deal and at 850 amps no cap can beat that.. I would for sure recommend it

Great battery.

Bought this for my rzr 800 to power my 40" led light bar and other various lights along with my radio. Still works perfect after all the bumps and car washes.

GOOD PRODUCT

bought this and installed it to solve a problem with my headlights dimming but it didn't fix the problem.

kinetik kh600

Bought it for my audio system and its super powerful, no dimming headlights, just awesome. Highly recommended. 100% happy

small and powerful

Battery is small for its powerfulness. Does the job well. Thumbs up.

Great,Small,powerful battery

I added this to my honda for more power on my 15's and I tell you it did it's job for how cheap it was

Great buy

Just got 2 kinetic 600s great batts keep my lights from dimming

This does the trick

After my alt. and Batt. Fried from the terminal becoming exposed ( the big 3 ) I dicided not to run 0 AWG to the alt any more Instead I got this awsome little battery and replaced my 4.4 farad cap and it rocks. My system is only 3200 watts maxx so combined with the huge battery under the hood power suply is no longer an issue. I have had it for over a year and it can run my 2009 corolla through 15 ft of 0 AWG on its own (I ahd to test it for fun). It fits by my spare tire so its compact design makes it invisible in my small sedan. Throw capacitors in the trash and get one of these instead!

Awsome Battery

I picked up 4 of these for my truck. Bigger Alt, and battery under the hood, and 4 of these in the back, NO PROBLEMS. No regrets.

NVX= Quality. End of story

I'm currently switching my entire system over to NVX. I've purchased all the wiring, subs, box, and sound deadener and have yet to be unimpressed. Do yourself a favor.....just buy NVX and quit wasting your time and money. I've run kicker for years and MTX (the old stuff when you could easily put double the rms to a sub) and in MY OPINION, NVX comes out on top.

Great Little Battery

Bought three batteries and am not disappointed best purchase I have ever made. Don't need a cap, no lights dimming.

Great Product

Excellent upgrade for those system lacking power to AMP. Will take your bass performance on your system to another level. For best results upgrade your car battery to a Kinetik 1200 or higher. Avoid combining with a wet Battery "Standard Battery". Keep the 600 Kinetic as close as possible to AMP.

Great Value!!

The best cap killer on the market

Good

Got it pretty quick and the battery works fine, small doesn't take up much space and was well worth the price ..I'd buy another.

Hc600

This product is awesome subs hit perfect will definitely buy more when I get my entire system up and running!

Long constant power

First off let me say, If your using a capacitor, you're wasting your money. These Batteries last twice as long as a normal battery and charge 3 times faster than a normal battery. If your system is slamming on going through a long period of bass, a capacitor will discharge so fast and it wont do any good after that because your bass is still slamming. But the battery will supply all the power you need through that bass. I was running 1200 watts with this as a reserve battery. It did the job but i would still recommend a bigger battery for that power. But I'm still impressed of how well it handled double the recommended power.

Does the job

Well being as tho I never believed in a power cap i feel like this battery is the best choice and being only $99 from sonic I don't see you going wrong. I also did the big three up grade and put in a mechman alt but alt was still dropping down to 13.2 volts, bought the cap killer and now she don't blink when the beat drop!!

Kicker Everythang!! Zx1500.1, 2 Kicker Solo Classic, ZX 550.3 pushin 61/2 Infinity Kappa Perfect Components and 4" Infinity Reference in the rear.

I'm not killing my starting battery

I have my hc 600 in the trunk of my car and with an kill switch between it and my main starting battery....now I have no worries when bumping with the car off.

Great product

Awesome wire for the money. Looks great and easy to work with.

With The Best of 'Em

I've been a car audio nerd/enthusiast for literally half my life; I'm 30. I am not nearly as involved in the hobby as I used to be, but I have seen plenty of things over the last 15 years...and there has been no shortage of variations of power wire.

That being said, this NVX wire hangs with the 'Big Boys' or 'The Best of 'Em' at a very reasonable, or the best, price. It is true to it's AWG and is just as flexible as the Kicker wire; which became my standard for comparison years ago.

The picture for the item listing doesn't do justice to how the wire is wound/bundled. It is a honeycomb, 6 outer bundles with one in the center. Since the wires are nicely wound together it takes much less effort to get a tight twist to easily insert into a raw wire input. I'm assuming this contributes to the flexibility of the wire as well as minimizing fraying when you cut it; which is a plus. While on the topic of cutting wire, you NEED to pickup those XScorpion wire cutters...They're nothing short of amazing...Even cutting 0GA effortlessly!

The shielding is wrapped/applied to the wire very tightly, yet is still forgiving enough to cut it and easily (enough) slide off the end to attach a ring terminal or slide into a raw wire input.

Wire accepts solder very well even without applying any additional flux.

If you are curious as I was regarding the silver-tinning of the wire I have some interesting and good news for you. A google search leads to minimal useful/helpful information with people leading you in both directions as to the usefulness/purpose of silver-tinned copper. Well, a friend of mine does construction for a living and had some short lengths of industrial grade 2GA wire in his garage. I was looking at it the other night and to my surprise found it was silver-tinned as well. This tells me it must provide some benefits(At the very least I presume it is for corrosion resistance) if that's what they're laying in the ground and running through buildings to provide them with power. Take this as you will, but I believe it's a good sign.

All in all, you shouldn't hesitate to buy this wire. And most importantly don't be fooled by cheaper wire that has thicker shielding or is copper coated aluminum!

its more then a battery

I love this little thing. I got to help with my stereo system. But it did much more than that, it has help my whole electrical system.

good product

I would recommend this product to anyone looking to stiffen up their audio voltage. It didn't cure the power drop 100% for me, but I'd say 75% is solved.

Not for under the hood, or cold weather

Good battery to put in the back for support juice. Went from dropping to 11.5v to steady 14.4. Running 2 Soundqubed HDS200 15's on a hifonics 1700.1

Glad I did this

I have 1600 watts in my 01 Monte Carlo SS and had a 2 farad power cap that was installed and I never liked it. Every time my subs would start hitting my lights would start dimming. Now that I have thrown that away my system sounds better and hits harder and my light's don't dim or wipers don't slow down. I can also keep the system turned up at a complete stop with the a/c on full blast the lights on the wipers full blast and my lights don't dim any more and don't have to worry about blowing a fuse or any thing else this is well worth it's weight in gold. If you have major bass in your vech then you need one of these period !!! Don't even bother with those farad caps any more!!!!

Trunk battery

I have this battery in the trunk of my car, supplying current to my subs and door speakers (900rms to my Jl12w3's,and 600rms to my doors)
this battery in combination with a Kinetik HC 1800 in the front (2x runs of 4awg from front to back)
with the car running, my voltage doesn't drop below 12.8 unless my headlights are on!

If you have subs that make your lights dim, or are considering a capacitor... THIS BATTERY is exactly what you should consider. For the same price as a decent capacitor, you get a battery that can power 1200rms without breaking a sweat! :)
(This battery has more than enough power to start and run your car, so you could swap your stock battery for this if you want to save some weight!)

Awesome battery!

I had this battery installed as a second battery to a 500 watt amp and the voltage never dropped. Awesome addition to almost any system.

Bang for your buck

Loved using NVX wire in my build. Just a note it is silver tinned copper wire and not pure silver/copper. Cable is very flexible and the insulation is very durable. True spec wire, no shortage of strands here. Make sure you order more than you need and you will have no issues.

Kinetik HC 600

This battery (for the price and size) is very powerful, efficient, long lasting, and performs better than I expected, I recommend this to anyone who wants to add on some punch on your existing battery or who is into installing a car radio on a power wheels vehicle. This battery is powering my son's vehicle's sound system (300-watt amp, also hooked up with a capacitor) on 2 (6x9 speakers) for about 5-6 hrs straight with no problems, trust me, if you're still in doubt.

works good

works good, i dont know if it was the right one for me though, so i got a yellow top..after i got his one cuz my lights where still dimming. now they dont hardly dim at all..and i have a 1000.1 amp and 350.4 both are kickers.

Incredible

all i have to say about this product is that if you have any issues with your lights dimming on the inside or out, this will either minimize it by a lot or even just eliminate the issue period. in my truck it takes a whole lot now for the lights to dim just a little bit.. i've even ran my truck for an incredibly long time without having the battery being killed. great product.

Great value!

Best wire for the buck. Appears to be the same wire construction, materials and amperage rating of the Kicker and Rockord wire. Silver tinned ofc. Doesn't get any better than that.

By Luis on December 29, 2015 Verified purchase

Awesome service

I ordered this battery a month and it came very fast. But these people who sell these items are great, I mean I didn't do a review because I was very lazy. But these people contacted me to make sure I was satisfied with their product. Honestly I am and what makes me more pleased is that fact that they checked up on me. Great service, keep up the work.

great value

Its a great product, small and simple to hookup and preforms great

It works great, just not in my car.

I never hooked it up in my own car one of my buddys has it but it works great as a 2nd battery.

Cheaper than Capacitator work better than Capacitators

Great battery for the price recommend it to anybody. Can push a 900/5 JL audio amp with components speakers. A JL audio W7 10inch subwoofer, which takes all the power and it was the main reason why I added the extra battery. After that the lights weren't dimming anymore. I did my look around and they told me capacitors are a joke.

Excellent Work on Kinetik

I have this product and all I have to say is wow Kinetik rocks I have a 2,200 watt system with specs below:

Rockford Fosgate Amp - T1500-1bd

Good wire for ground cable

I used this wire to ground my amp. It works great for that.

By Michael on March 3, 2020 Verified purchase

Great wire value

I chose NVX for all my wiring needs; from the silver tinned OFC for power, ground, and speaker wires, to the RCAs. After my research, these were the wires to get; and the pricing here is great.

small wonder

I read through some reviews and seen how positive they were about this battery. I ordered it and i am surprised at the amount of power my increased. I have 2 Rockford P2's and they hit hard now. Im very pleased with my purchase.

Works Great

It does what I need it to do its actually a litte surprising how small it is yet it works so well. I still need to upgrade my alt. But this definitely does help with the reserve power I also got that metal holder for it to securely mount it into my trunk which I definitely recommend also

A good deal

I only have one and it kept voltage drop to a minimum no light dimming at 2000w RMS but you have to keep it charged my only problem was the screws aka terminals that came with it did not screw down far enough to make sure the wire rings had a good connection to the battery I thought it was okay at first but after playing for a while the battery was fire hot had to use a couple washers but fixed the problem

awesome product

Just what I wanted a battery that was small and powerful fits anywhere would highly recommend

Buy it. It's a No-Brainer Deal.

For only twice the price of a capacitor, ya get soo much more. I have one of these wired in parallel with True 4-Guage Monster Power Cable up to the DuraLast Gold up front.

At first... I had a cheapy in-line fuse holder that was defective (the cylindrical fuse kind). Took me a while to figure out what was wrong because this little battery being out back right next to the Pioneer GM-D8500-M and GM-D9500F powering them directly was good for full-throttle volume pounding for a good 45 seconds before it would mysteriously (mysteriously to me at that time) would then start to have output fade out. Used Multi-Meter, figured out that cheapy fuse wasn't passing the voltage along... replaced that cheapy fuse with a nice quality Monster ANL fuse and no more problems. Just bothered to tell that story so ya see how much oomph that little sucker has even all on it's own!

Good product

Looking for a second battery with not much space, then this product is what you need. I had light dimming in my 2004 MB but after installing the HC 600 that all went away and my sound got better. For the size and great price I would recommend.

cool hybrid

Ever since i had this hc 600 in my car i haven't had any problems with my battery . I put this in my car more than 6 months ago and not a problem i had multiple amps hooked up and the lights stay bright . This product is a great buy. I had capacitors before but this is the boom digidy

"Great Value"

This small baby worked very good on my car, since I got it never have more problem with my system, I use it like back up to my amplifier so if you can afforded it buy this one, you will get more power for a great value....

Great Battery!

This battery is the smallest and lightest battery I have ever seen for a car. It's great for racing, but not so good for running a sound system. If you want a good battery for a sound system I would recommend getting one of the bigger versions of this battery which you can find right here at Sonic Electronics for a great price.

HC-600 kinetic battery

Amazing product if you want that extra power for your stereo system. Great power adder perfect idea for the audio enthusiast.

Mo Powah Baby

Real copper, Real 4 gauge, very flexible, very nice insulation that doesn't hold stains in the engine bay. held up nicely for 2 years so far.

20ft was enough for my Acura RSX both power and ground since I did kind of cheap out and used the same color for the ground but with some black heat shrink every 6" to identify it.

By paul on March 31, 2021 Verified purchase

Great

Wire was easy to install with no distortion and feed my amp with lots of power

Great wire

Great wire it’s a true 4 gauge that’s easy to use and to hook to your amp

The REAL DEAL

Yes this wire is the REAL DEAl and with so much cheap copper plated aluminum Chinese trash out there it is both refreshing and a releif to have found this wire.
You don't have to tell me how true gauge your wire is if you build it to be rated for AWG standards.
Premium OFC wire, its not cheap but you get what you pay for in this world.
Great wire that can handle the power without losing your wattage to heat.

Great Product/Excellent Value

Used this on my 05 Corolla to do a Big 3 and run my amp. Super flexible which made the install much easier and save a ton of $ instead of buying a Big 3 kit and an amp kit.

Excellent Cable, Great Price

I was extremely happy with this cable; it's extremely ductile and easy to work with in the tightest conditions. Add a few drops of liquid dish soap, and the silicone jacket becomes near-frictionless for long/complicated pulls. Build quality is excellent as are the materials.

GREAT WIRE,HIGHLY RECOMMENDED

I bought the nvx ofc 4 gauge AND IS NOT ONLY A TRUE 4 G WIRE BUT SILVER PLATED,VERY FLEXIBLE BEST PRODUCT FOR THE PRICE!!!,I WOULD RECOMMEND THIS WIRE TO ANYBODY!!!

big juice in a small package!

this little battery is holding its own. its hooked up to a hifonics brx 1400.1d with two cryptic 15 inch subwoofers in a big 3 cubic ft per speaker ported box and it is super loud. i had a light dimming issue that was bugging the hell out of me,but i knew what i had to do.my 130 amp alt and new battery was not enough for that amp tho,but this little joker here with a battery isolator was absolutely the best thing to do.capacitors are a waste of money unless you have the battery and capacitors together. oh and i dont have the big three upgrade just 4 guage normal wiring. bass epicly my friends!

Very good

This works really good. I love this thing. In addition to the 2 farad cap and the yellow top under the hood and 0/1 gauge everything it keeps up the volts and lets both my sub and speaker amps blasting. Highly recommend to someone whos looking for more power on a budget or who doesnt want to dip into anything to mechanical!

great addition

This little blue battery really packs some punch i have older Honda that has no altanator upgrade just stock 60 amp was having huge light dims even interior light would dim when bass hit wish i could upgrade altanator but 60 is max but no wories cause with this kinetik life saver no more dimmning lights car even turns over faster bass hits harder amps runing lot cooler now as well deff get one if you want more power for the buck also caps put strain on alt so that says it all shortens there life span thanks sonic great price.

Wow! Great battery!! Recommended!!!

This is a great battery. It actually powered my 2340 W RMS system by itself for 10 minutes at 3/4 power. Even then it still had 11.8V. If you want a little insurance, this is freaking awesome!!!

RUNS MY YAMAHA GRIZZLY 660

Put this battery in my Yamaha Grizzly 660 after the OEM battery took a dump. It was originally in my Dodge 1500 next to my amps. But after a new truck and a new install it sat for 2 years in the garage. now has been in the Grizzly for 2 years and hasn't even stumbled. Runs the winch and all. Hold charge all winter in storage. and is only $30 more then factory battery.

this bat is no joke

Installed this bad boy in a neighbors ride; before this guy amps would almost stall the car out, car needed alternator upgrade, put this little guy in for a quick fix. This thing is unbelievable, no dimming headlights, no more problems at all! What a great product! From Sonic great site, great people five stars to seller and product THANK YOU!

kinetik batteries

this is the best way to go , beats any capacitor out there, and cheaper than some of them to . it is about the same size, and easier to hook up because you don't have to charge it . 10 out of 10 rating !!!

Great Battery, Great Value, Super Service

The best battery, super happy with the service thank you Sonic Electronix

HONDA INSIGHT(JAPAN)

I changed my HONDA INSIGHT12[V] main battery to HC600 for 6 month ago. It's light weight but has big power, thank you.

idk

i just want to let people know this battery isn't meant to be your main battery, its made to be wire in with your current battery and acts as an extra power supply for your battery.

Best Battery for $

Capacitors are not a good alternative for dimming lights and more power. I run this amp in parallel with my front battery. It is awesome for the price. I get no dimming with 1700W RMS. I use to run 900W RMS and got dramatic dimming. My power wire to the amps are short because the HC600 is in the trunk. I would get this battery or any other of Kinetik's batteries.

Light Battery

I'm currently using this as my only Battery in my car. It works great, but doesn't last very long if I have the car off and music on.

Best battery ever PERIOD

Well, ever since I put this battery into my system I get absolutely no dimming, EVEN AT FULL TILT! . It feeds my amps with the current they actually need so ... Get one if you can afford

kinetik

i would recommend the kinetik battery, its way better than buying an lightening cap. you can leave your car off and play your music w/out worrying about your main battery. I own three of them, the 600 series and the 800

Great bat/cap combo replacement

Added one of these to the trunk along with an HC800 under the hood for main/starting power. There has been a huge reduction in dimming and the car even idles smoother while warming up. These things are sweet!

saved my life

without this cap my ligts would dim everytime my sub thumped and now it has no trouble watsoever, u might as well get the 100fared for a little more.

Just what you need.

I used to have a 2.4 frag cap in my truck. that still let the lights dim when the bass really hit. Not with this unit its a perfect mix of a battery and cap in one. i have no problems with my lights dimming ,nor my battery freaking out. you should really think about this product if your pushing some watts.

Great price, material, and shipping

Every person on earth should have a pair of these connectors

Great product great value

I would highly recommend the purchase of this product and it is delivered jimmy John fast

Great Value

Best price per foot out there. Great quality, made from real Oxygen Free Copper and not Copper Clad Aluminum which is hard to find. Covering is very good quality also.

Awesome Power Wire for the Money

Really like NVX brand for the price. Top Notch quality.

I like the cable design

I didn't need this much but the price was too good to pass up on. I only used about half to run my 2 channel amp since my battery is located in the trunk already. Low resistance, great voltage readings. I can't find any flaws in this cable. Thanks Sonic Elextronix

kinetik

Really good product if you have dimming headlights!

Great Product!!!!!

I love these batteries they power both of my Planet audio amps without missing a beat.

Fantastic battery

I've just ordered a couple of these to supplement my car audio in a '34 hotrod. These were the only ones that would fit in the tight area of my hotrod interior. I've got 2 amps...a 600 watt stereo and a 2000 watt sub amp...(Hifonics) running off these. They work much better than caps and really help the system. I will definitely be ordering more for my other vehicles. Other brands don't offer the various sizes these guys do and the prices rock...Go Kinetik's!!!!

Smallest holder ever

Love how small this is. Fits wherever you want

Great battery for portable stereos

I bought this to power a floating radio that I built using a marine deck and 4 6x9s. It powers it all day long and has never died on me. You can mount it any direction and it's pretty small so it fits anywhere.

awesome little battery

I purchased this as a secondary power source for my 4Wheeler stereo works great never had a problem with kinetic products I run a hc1800 in my jeep very good batteries.

more power

I have a surveillance van and use large powerful 12 volt truck batteries for ac inversion....I got 2 of your khc600 batteries in parallel ...no need to check battery fluids...very happy with your batteries output...I have found a new way to invert some of my power.....thanks

bad mofo

I have this hooked up to a fosgate 1000bd @1 ohm with two sundown sa 12 s and still my lights don't dim I will be getting another and chain them to get her wen I get my 1500 bdcp

Reliable!

Stops all lights from blinking provides enough power for systems with amp with 1000 watts and UNDER or you'll need two..

GREAT VALUE

Great battery!

Kinetik hc600

Small size and packs a punch for small systems. Added it to protect my alternator. You do need a bettery isolator and I added circuit breakers for added peace of mind. System is running a constant 14v with system cranked up. No dimming of light when headlights are turned on and no dimming in interior lighting. System is running 750rms, 600rms to one JL W6. If you are going to run a system 800rms and up get the 1400 or go bigger just to be safe.

No cons whatsoever.

Very Pleased

I built a fiberglass sub box with 2 12" subs, a tv, an xbox 360, and 2 speakers. The kenetik HC600 powers all of that with no problems at all. Great product.

Power

I have the HC600 hooked up directly to a MTX TE801D amp in Cadillac DTS, along with the factory battery. With my system playing full volume I maintain 14.2 - 14.9 volts constant. Even during heavy bass peeks the power is there. The lights don't so much a flicker. This power cell really does a great job. It's small and packs a punch. Great value if you know how to use it right. Pick one up......

Kinetik HC 600

amazing product if you have a nice system and looking for the extra power instead of draining the battery in the engine bay then get 1 of these amazing product well worth the money if you are into audio.

Kinetik HC600

Awesome battery works great with my 1,000 watt sound system. Would recommend

ofc wire

Needed to step up my power wire, this was all I'll ever need. Pushing 1700 watt RMS Sound stream with ease.

Nothin out ther better

The only thing I think will out due this capacitor is an actual battery. And if u want to something that huge in the back of your trunk then by all means be a rookie. This CAP is amazing for it's price. Funny story! I jumped my wife's Chrysler with this thing. Definitely 5 STARS

good work.

i know im pulling alllllllllot of power when i have one of these and a five farad cap hooked up and my lights still dim. when the bass hits at 30 hertz it only drop to about 13 on the reader. GREAT WORK kinetic. prolly gonna have to get either a better alternator or another battery. but without this i would prolly blow every fuse in the car and mess some serious electrical stuff up

Useful

Used it in place of a cap and it works better than a cap. Very small and weighs as much as an amp. A must have for cars with low current.

Awesome

I used one of these in my 1986 Z28 Camaro for my sound system. It worked so well that I ordered two more for a system that I built for my 2006 Dodge Charger. I am extremely happy with the product ad recommend it as a auxiliary battery.

Cheapest true 4 gauge

This is a great product. It's the cheapest true 4 gauge on the site. Be on the lookout for anything cheaper that says 4 gauge because it won't be. Sonic is able to give you a great product cheap.

Flexible

I love this wire. I've used it for several of my builds. It's been a few years since I've installed any and I did the other day and it's just so flexible and doesn't really get bent up when put in tight applications. Easy to install and 100% OFC. The 4g is what I bought and it's definitely true gauge power cable. Would recommend to anybody looking for a great power cable and on a budget. Worth the money.
