Customer Ratings & Reviews

Good

This wire is very flexible and fit nicely in my 2000 nissan maxima. ring terminals were a little fussy, but that was operator error. very nice 150 amp fuse. Lots of wire crammed into it. Very inexpensive for the quality. I would recommend this to anyone looking for an upgrade.

Great

It is what it says it is.. no problems with install.

a great kit for the price

these are great for the money and would definitely buy again

Decent Amp Kit

I am a professional installer first of and my father is an electrician. Following the AWG- American Wire Gauge standards this is not 1/0 wire it's closer to 2AWG, please understand that true 1/0AWG copper wire will cost around $5-8 a foot.

That being said for the price it is an amazing kit but should be marketed as 2AWG.

When compare to Kicker and Memphis true to spec 1/0AWG wire there is a major difference in size and weigh over all. 5 feet of Memphis 1/0 Wire weigh the same as 17 feet of Belva 1/0AWG.

Great Wire

It's the size it says it is, and powers my 1400 watt system with no problems. For the price and ease of install, I couldn't be happier!

top quality

I got this kit on a deal with a amplifier I purchased thought it looked good turned out to be one of the best amp kits I have ever owned would of paid full price for it

Great deal

I got this kit because I got a deal on it with my amp...great starting kit...didn't have any problem with it when I installed it...The ground cable was to short for me but that is due to my custom box..All in all good 1/0 Guage kit

good product

Good product, they give you plenty of length. Only complaint is that the o connectors are really hard to clamp down and the rcas are kinda cheesey but work

Huge

I have never ran 0 gauge before and when I got it and took it out I was surprised but the big wire didn't really hurt the install it is still hidden under the carpet and it's thick and flexible so it was easy to run through the firewall. Now I'm gonna get the Belva big 3

True 0 AWG!

Pros:
This kit comes with everything you need for a 0 AWG amp install with RCA inputs.

Cons:
NONE

I would definitely recommend purchasing this kit if you need a quality 0 AWG kit at a fair price with super fast shipping!

Belva BAK02

For anyone looking for a budget amp kit, this is it. It is TRUE 1/0. I even measured it. Just got it in the mail after about 5 days total since ordering. Shipped very fast; thanks Sonic Electronix. Awesome deal, nice and beefy wire.

Belva Amp Kit

Good product. Quality parts.would recommend to anyone needing a 0 guage kit for a good price.

Great Value

Great items from this place, more orders will be goin from me.

GREAT KIT FOR THE MONEY !!

Good kit , ive seen better but not for the price . Well worth the money!

great amp kit

The power wire is real thick, looks like a great amp kit, Rca cables look awesome. Only thing that would make this amp kit better would be to include speaker wire. Crimp terminals are a bit hard to install
But over all great amp kit.

Great kit

The kit is good has mostly everything you need
, although I recommend getting a longer ground wire due to it being short , only downfall other then that great kit for a sub amp n other amp install worked great for my sub amp and 4chanell although I needed a few more wires for adding the second one

Works just fine!!

No problem with install or power. Everything needed was right in the kit. I would buy this again if I needed it!

GOOD KIT

IT IS A GOOD KIT FOR THE MONEY. THE TERMINALS COULD HAVE BEEN BETTER. THEY COULD HAVE SUPPLIED BETTER 0/1 GUAGE TERMINALS THAT WERE EASIER TO USE BUT STILL A GOOD PRODUCT.

Real heavy duty kit. Real amount of 0 Gauge included.

This is a very heavy duty amp kit. The wire is huge compared to other brands I've used in the past. It's flexible and easy to install. And it's really a lot cheaper priced than other top brands. The fuse holder is nice too and I like the color of RCAs. Like everything with Sonic, always fast shipping and great stuff.

Order

Never revieved I have a trache and am unable to speak on phone I sent you a letter but no response yet it wouldn't submit my review till I checked start I can't answer when I have not recieved it.

not what u expect

I would not recommend this product because. It I only a little bit bigger than four gauge. I do not know how they market this product as zero gauge. Next time I just have to spend the extra couple of bucks.

Budget amp kit *thumbs up*

This is a good quality budget amp kit. Power wire is almost true size and soft and flexible. Everything was exactly as described and no issues at all getting my system installed with this kit. The twisted pair rcas are nice and I have no noise pickup with them. There was even enough power wire left over for me to grab a few extra ends and do the big 3. Definitely recommend.

Great Budget kit, with a few shortcomings.

Overall this was a very good kit, with thick high quality wiring and heavy insulation. I saw no factory flaws, and since installing it I have had no problems. It did however lack a few things, which bugged me. The first was that neither: the ground, nor the power cable came pre-clamped, this wasn't a huge deal as I had access to a vice, but for those with limited tools, they may have trouble creating enough leverage to cramp the metal ends tight enough. Other then Having to clamp the ends myself (again, only an annoyance if you don't have access to good tools) the kit has performed flawlessly, and is a great value for the price.

Good Wire

I was skeptical about buying this wire, but to be honest it is definitely worth the money. I would invest in some new RCA's though, the ones that come in this kit aren't that good!

Great Value

never bought another brand. belva has always been easy to use and held up very well

AWSOME PRICE

Very good quality. Very flexible wire. Very pleased. Will be ordering again when i need it

Pretty good

It was hard to install but when I did I got the extra burst of energy I need

bIG OTT

It is a typical wiring kit for a system. It is a little short in my 03 suburban, so I just mount the amps under my sets directly behind the drivers seat.

Good for the money

Bought this kit because of cost. Fuse holder is of good quality. RCA cable is nice. No noise. Plenty of remote wire for amps. Power and ground are very flexible. Wire gauge is a little smaller then zero gauge but not like some other kits. All the terminal connections are included. In the end, good product for the price.

Wire is great but terminals are hug

The wire is great and seems to be true 0 awg. However when going to crimp the open barrel ring terminals to it they are literally twice the size! Have to go buy new ring terminals that are the proper size.

Sounds awesome

I installed these in a SubThump box for 2013 silverado. powered by Rockford Fosgate R1200.1D amp at 1 ohm I like headroom so this setup works great.. They rock hard!!

Best quality for its price!!!

I've been using this kit for about a while and the products are still in great shape. using it to power my audiopipe 3000.1D amp and two american bass xfl 15"s. wire in never hot. flexible. but the wire easily spreads apart for the cut tip/end if your not being careful and makes installing into amp/fuse box, etc ... more difficult.

Belva BAK02

Installed this wiring kit three weeks ago, very nice quality 1/0 gauge! Works great! Ended up buying some screw ring 1/0 gauge terminals because the crimp terminals it came with are a bit difficult to install. Other than that, very good product!

wiring kit

Great kit for the belva bb5000 wire size seems small but i just used it for the big 3 now im running skyhighwire still a great kit for a beginner just not for me

Excellent!

I bought this for my husband for his birthday and he loves it!

Durable

This is really nice and gives my amp the power it need to function haven't had no problems with this kit yet.

By Quentin on July 25, 2022 Verified purchase

Nice heavy duty kit for a low cost seems to be working well with my system.

By Diego on June 3, 2020 Verified purchase

This wiring kit fulfilled my expectations . No noise interference and very high quality product !!!
I highly recommend this kit for anyone installing an amplifier in their car !

Simple and great product

This was a cheap and effective solution to hooking up my system only thing is it isn’t true 0 gauge wire however it does the job and I would recommend it.

By Clarence on September 7, 2023 Verified purchase

Great price.

Says 1/0 gauge probably more like 2/0 gauge. Comes as you see in pictures.

By Tyler on August 7, 2022 Verified purchase

Get It!

Good item. Did the job like it was supposed to. Would purchase again from sonicex

wow got jipped

this wire kit is nowhere even close to 1/0 gauge. even if it was pure gold it is probably a strong 4 ga in a 1/0 wrapper. very flexible and nice looking. the fuse holder isn't too bad. eh, i got it on sale.

By Brandon on April 15, 2016 Verified purchase

amp wiring kit

this wire is seemed mighty small to be for being 0/1 gauge wire but still getting alot of wire for the money. just be ready to buy end for this wire to hook up your cap/amp because this wire for me was way to big to fit in any of the amps/caps holes/connectors for wires

Good kit

For the price this item is great. It’s half the cost of a true 100% copper amp kit, which is why you get copper aluminum mix and cheap connectors. But like I said it’s perfect for the cost and works great

By Chad on April 15, 2018 Verified purchase

Decent amp kit for a cca kit. I have it feeding a brutus brx2416.1 and seems to do good

By Anonymous on September 11, 2018 Verified purchase

True 0 gauge

This is exactly what it says it is. I measured the wire itself at slightly over 3/8 inches. Which is exactly what 0gauge is. There are brands out there that are thicker, but they are oversized. Several companies make oversized power cables. But this IS true 0gauge.

Best buy

Best 1/0 kit for the money. I melted my 8 guage kit running 2250 rms to 2 power acoustik mofos. This kit got me squared away and us ready for more power.

By D on February 28, 2018 Verified purchase

Good Kit

This kit came with everything I needed to upgrade from my old wiring kit. It had a few things my old one didn't that would've been helpful if it came with some directions of sort, I figured it out but would've been nice. Also the wire terminals could be alittle better quality.

By Alex on August 5, 2017 Verified purchase

This wire kit comes with heavy duty wires and pushes my 3000 watt system with no problems.

Amazing kit!

Wiring kit is amazing. perfect length for what i needed and holds power!!

By Blaze on January 10, 2018 Verified purchase

Awesome amp for the price

You will not find a more powerful amp any where else for 120 bucks. This amp is perfect for anyone seeking power on a budget. And its strappable. What more could you want?

Audio Tech In Fresno Car Audio Installer

We sell these amps in our store that i work at and i have to say, im really surpised what power comes out of this amp, it may not be true power but to get the most of it does require a good cap or extra battery, 0gauge power wire with the big 3 aswell. 0 to 4 gauge splitter for the 4guage amp inputs. a good stereo like pioneer or a simple jvc headunit. and a fan to cool it down since it doesnt have a cooling system so to keep it from getting hot. and some good subs like kicker or re audio. it would sound awesome. from Fresno CA, this is my review and i reccomend it for this price.

Alright but the usual issue.

This amp has a great price but I have noticed in the 6 months that I have had this as usual BOSS once again overrated this amp. 2100 RMS you say? It hits less hard than a 900 RMS kicker. It's decent but you can get better. Doesn't over heat and lasts.
I wouldn't recomend it since it is overrated. Spend the bit extra and get a quality amp.

Alright

I was hesitant to purchase this product due to the same reason as the prior review. Boss tends to overate their wattage and that's what they did. This is pushing out less than my friends 1500 Kicker amp. Looks decent and doesn't over heat often. Decent but not the best.

great value

This product is very good and its durable and when I installed it I just fell in love with with it.

good amp

Got this in a mustang convertible and it was hard to get bass sound with top down this help a lot.would recommend this amp.got two 10s and wow what a big difference.

great amp

best mono block iv've ever owned great on my two 12 in kenwood subs .

Good Amp

Great value I have only used it for about a month now and have had no problems. I am running 2 10" Kaption subs and they sound great.
surprisingly pleased how well this amp works.

Ejay Johnson

I recommend anybody to buy this amp. I wasn't a fan of Boss but I must say I love this amp. I have a Grand Marquis and this amp has those 2 Kicker Comp CVR's dancing all in the trunk

Boss NXD4500

This amp is amazing. Just make sure that when you ground it to your vehicle that the ground is solid. Have no other problems. Keeps the bass going and no shorting.

A little thump in your trunk

In the last few years I've owned about 4 different Boss amps and have NEVER had any problems with them Including this one. Whether or not Boss overrates their products remains to be seen. People who say they do, most likely have heard that from someone else who heard it from someone else who heard it from one of those people we like to call "know it all's". Not once have I read about someone actually putting it to the test themselves. Anyways, I bought this amp about a month ago and over all, I'm pretty happy with it. I currently have it pushing two 12" pioneer premier's (ts-w2000spl). I've had it running at 4 ohms and it was doing just fine and pushing my subs pretty hard; verified by multiple complaints from my wonderful neighbors. Yesterday, I wired my subs down to one ohm just because I wanted to see how much power I could squeeze out of this amp. I'm not sure yet if I'm going to leave it that way but we'll see. Needless to say, I almost blew my subs. It did get a little warm so I've decided to get a fan or two for it just to play it safe. All in all I WOULD definitely recommend this amp to anyone! The one and only complaint I have is that the level, the subsonic filter, bass boost etc.. are located at the bottom of the amp instead of on the sides, which in my case with the way I have it mounted, makes it hard to adjust any settings if need be. I did a lot of research and probably looked at just about every other high power amp out there for this price and I'm pretty confident that this amp is going to be the biggest bang you'll get for the money. If you're on a budget and are looking for something with a good balance between being cheap & reliable, go for it but by all means if you got the chetta get something betta!

best amp i had

It is worth every penny this is my 3rd one. Price is great and it pushes 2 12 inch pioneer premier subs like nothing..

Excellent Bass

Using this amp to power my 1995 12" Volcano Cannibals (2) in a non ported enclosure. They POUND.

Working flawlessly

Simple setup. It works well and I would recommend it to anyone for a entry level amp.

Boss 4500w Amp

It was a little difficult to learn to use, being as I'm a novice. But it hit harder than any amp I've ever owned. The only real drawback I found was that after about a month, it stopped working. I don't know what's wrong with it, but if I can fix it, I'm putting it in my truck. I mean, who needs their hearing?

Good Deal

At first after i heard that BOSS was a low end brand, i was a little skeptic when purchasing this amp. However, even though they are a little over rated, this amp is an excelent add on to my sound system. i have 3 rockford fosgate P3D412's hooked up to it at 2 ohms and they sound perfect. I was used to having a hifonics amplifier hooked up to 2 12" rockford fosgate HE subs, but this however is 100 times louder and rattles my frame. Boss may not be a top quality brand, but don't let peoples bad reviews fool you. When it comes to the ONYX series, you will be happy.

Great Product

I just recently bought this amp with low expectations since boss overrates their products' wattage... So far it has worked great with my boss P126DVC subs.. I wish i would have spent a little more money on my wiring kit.. only have a 5 gauge power wire... shoulda bought a 0 gauge..

Overall Great Product...
So Far...

BEST INVESTMENT I HAVE EVER MADE!!! Name Brand Equipment Sux!

I have used amps & sub's that have cost me over $600ea. Recently I blew out two 10 " subs with a "high power" 1200watt amp. I got sick of paying so much money for name brand equipment but in my mind, that's what I needed to make my system hit hard. I didn't want to embarrass myself with cheap equipment so came up with a small replacement budget and I thought it would be worth it to buy cheap and sale them on Craigslist once I can afford to buy better equipment. WELL LET ME BE THE FIRST TO TELL YOU THAT BOSS AUDIO KILLED EVERYONE! If you want to make your friends jealous for less than $200 dollars then write this down. I will be posting a youtube video soon under GtekVIP.

FOR LESS THAN $200 YOUR SYSTEM WILL OUT-BANG ANYTHING YOU PUT UP AGAINST IT. This amp comes in 3 sizes and depending on your subs you make the decision. I noticed my expensive brands had amps with only 1200 - 2000watts max for almost 6-$700. Make sure your subs can handle an amp this powerful.

BELIVE ME... I thought the same thing. How can a Boss Audio Amp for $110 have 4500 real wattage. I Have No Idea How But It Does.

WRITES THIS DOWN:
Boss NXD4500watt AMP $110 or $100 with online discount, free shipping too.
Next I got 2 Boss Audio Phantom P160 10" Subwoofers for only $45ea.
TOTAL PRICE INCLUDING TAX $190 - $200 max!!
If you want larger subs get the Boss Phantom 12" with the NDX5500watt (you can hear my 10's three blocks away. I'm guessing the 12's would just be outrageously loud and over barring. )

I WILL NEVER SPEND MORE THAN $100 EVER AGAIN. THAN YOU SONIC ELECTRONIC FOR SHOWING ME THE LIGHT!

BOOOOOOOMING

Get things clear this amp is really amazing i never thought an amp could be too powerful but this one is! I got it wired to 2 12 inches boss p126dvc subwoofers and im getting a massage in the driver's seat. Im scared my back window will shatter. The car rattles like hell and I had to turn it down a little. My rear view mirror is unusable since it vibrates so much. It is cheap but it is powerful. Great buy good value fast delivery and so far no problems with it. I definitely recommend this product.

Well worth the low price.

This is everything you could expect and more. Theres nothing else to really say, its just great. Anybody saying its UNDERRATED obviously doesnt have their system wired up at 1-ohm. I have two 15s producing thunder off of this bad boy. Very sturdy and well made.
