Cheap kit that did it's job

Inexpensive kit that works great for the 300 watt amp I'm running.

Belva BAK82BL (Blue) Review

Overall this was a pretty good kit for the money. The one downside was I was missing the following and had to go out and buy these to finish my install.
One black rubber firewall grommet
One 8 Gauge Blue chrome plated ring terminals
One 8 Gauge Black chrome plated ring terminal
Three 18 Gauge Blue Spade terminal
Two 18 Gauge Black Spade terminal
One 18 Gauge Red butt connector
Ten 4" Black zip ties

No complaints

Good amp kit for the price. Not sure if it is true 8 gauge but at this price can't complain. Plus it is everything you need

AMP. KIT

VERY GOOD QUILTY PRODUCT AND HAD ENOUGH WIRE FOR PROJECT

Not worth it.

This wiring kit isn't worth your money. Just buy a decent one for $50 than wasting your time with this piece of crap.

By Ray on December 19, 2015 Verified purchase

Nice cabling

Product performs as advertised. Came with most of necessary hardware

Great Value!

Its a great wiring kit for the money. You cant beat it. Wires are nice and flexible, unlike other cheap wire thats stiff. Id buy again.

Just what I was looking for!

I purchased this to go in the trunk of my 1966 mustang. I purchased it after reading another review of an install in a mustang. It fit perfectly in the side of the trunk and did not take up a lot Space. Sounds great.

Works great

My issue was the strain my amp and subs would put on my battery, no more drainage issues, speakers still sound great, car runs perfect

Good Cap

This is a good cap. The issues I had was the resistor did not light up when charging. To charge this cap, put the resiston up for 10 seconds or so. Once charged, when you go to finish the install the cap should be in the 12 volt range. I bought this to replace a 500k scosche cap. That cap ways way too small and point less being that I have a 2000 watt belva monoblock. This amp work really nice. It goes great with the belve amp. For 40 bucks, you will not be unpleased with the purchase.

Must Have

This is keeping the power flowing. Preventing that drain that comes from running 2 amps.

Great CAP for the money

I would highly recommend this CAP and the BOSS 1100 Watt combo. I have it hooked up in my F150 with driving (2) Kicker 12" COMP Subs. The amp combined with the 2 Mf Cap makes these subs rock. The Bass is clear and solid with virtually no distortion. My daughter liked it so much that she asked me to install one in her GMC Serria. I am about to purchase a third to install for a guy at work.
Would I recommend this amp to a friend?....Hell yes without a second thought.

By Steve on January 5, 2020 Verified purchase

Great Product

The product works great! I am very satisfied with the performance of the capacitor.

the product i need when i need it .got it so when needed i will have it .

it do the job my light are a lot brighter in side and out it works for me all my cars have one .

Good Price

Purchased so my lights wouldn't dime while riding around bass'n they still do but just a little and it definitely improved the sound.

Very good wire for subwoffer install

The wire looks like good quality and had everything I needed for a subwoofer install

Great for the money

For wiring up a smaller amp or a full range amp, this kit is perfect.

By Jon on February 23, 2018 Verified purchase

All the materials where there that I needed. The package was a great help.

The value,quality and durability of all the products Sonic Electronix offer sale themselves.

Great Product!

Best wiring kit for the money spent. I have Installed multiple systems all with Belva wiring kits,not a single complaint.

By Tyler on January 1, 2017 Verified purchase

Solid kit for the price!

I used this kit to install an NVX Quick Bass 8" self-contained subwoofer system in my Ford F-250 SuperDuty. The wiring overall is a good quality for the price and the length of the kit gave me plenty of options as to where to mount it in my truck. For the $15 I paid, it did the job and the subwoofer sounds great. The kit was well-packaged and had absolutely every terminal, zip tie, etc that you will need when installing. So in short, hard to beat for the price!

By Scottie on January 27, 2016 Verified purchase

Great value

Easy installation, great quality, and does what its supposed to do!

By Mouaying on May 29, 2020 Verified purchase

Good for the price

for the price I really like it. Small wattage wiring only. And it's easy to bend into place

By jeff on March 22, 2017 Verified purchase

Great Item's

I would recommend this item for anyone that is just wanting a little boost in their system, priced right with quick delivery. All in 1 great idea

Belva BAK82BL (Blue)

Wire is flexible and had more then enough pieces for configuration.

Far superior value than other kits

I am not normally compelled to write such a lengthy review, but felt I had to given my "TOFTT" attitude with the 1 star review I had read.

The thing that drew me to this kit was the price and reality that the other inexpensive kits look like a joke (see Boss Audio KIT-2 or Install Bay AK8). I am really happy with this kit as it provides way more wire than the two aforementioned kits and provided plenty of throughput for my set up. On top of the quality, it matches my blue theme so I am happy with the aesthetics too.

One personal note on the reviews of this kit versus others: I considered the other comment about $50 kits (and looked at the NVX XKIT82 and Kicker CK8). I put thought into those kits (Pure copper vs CCA) and watched the Sonic video, but the reality is I am running a 400W RMS two channel amp (Rockford P400X2) and for not that long of periods (never more than a couple of hours). The wire never gets hot, it's still made up mostly of copper (confirmed with Belva tech support), and it saved me a ton of money.

Reality check time: Save yourself $20-$30 and get *this* kit vs others if you are running less than 500W RMS.

Speaker wire

Great kit just make sure you buy separate speaker wire the wire in the package is very thin dam near no copper just casing.

By MARCUS on January 20, 2020 Verified purchase

Belva for the win

Great product. I have the MTX Magna sub system and the wires worked perfect. That system is small compared to others like it but it rattles my eclipse that you would think I have vibrating seats, love it

By Johnny Lobos on March 30, 2017 Verified purchase

Great bang for your buck!

Installed this in a 2017 Subaru Forester with a Kenwood after-market head unit. Everything seems to be of great quality so far, except for the remote turn-on the wire which is rather frail. Highly recommend!

By Nick on May 10, 2020 Verified purchase

Good buy

It is a good product. But it could have a longer power cord. I had to run my power wire a different way. Every thing else was great.

By Salsage on January 25, 2020 Verified purchase

Good product

Comes with 17' of power and remote wire. The quality is good and comes with what is needed to get an amp and subs going.

By Jason on January 13, 2020 Verified purchase

Like a good one to I wood bye it again

Great budget cap to reduce headlight dimming!

I have had this model of capacitor in my car for about 7 years now, with zero issues. This helped the headlight dimming in my Toyota Corolla alot, though it did not totally eliminate the issue. That's not the capacitor's fault: my system includes two amps (subwoofer and 4-channel for the speakers) with a total RMS output of 900 watts, and I'm still running the stock 80 amp alternator. Even with 0 gauge cable for the "Big Three" upgrade, I'm fully aware that the charging system is being pushed to its limits when I have the sound cranked.
However, this capacitor is an excellent value for the money, reducing my headlight dimming for only $35... alot cheaper than spending $300 or $400 on high output alternator. Again, I've been running my current system for nearly 7 years now and have had zero problems with the capacitor, the car or any of my audio equipment. As a final note, this cap is pretty small in size, so its easy to tuck away somewhere. I stuck mine under the driver's seat, right next to my sub's amp (pic attached).

Great value!

Sonic Eletronix always has good prices and also shipping is free as well fast.

Much better than Boss kit

The Belva kit is vastly superior to the Boss Kit 2, great value.

its ok.

thought would be decent for the price.. then when I actually had the time to hook it up...half of the LCDs on the LED display doesn't work.....imagine that.... hince why the price is the price.

By Doug on November 27, 2015 Verified purchase

Complete kit

I ordered the kit with an amp. The install kit was complete. Seems other kits never have all the pieces. Great value!

By rick on March 17, 2023 Verified purchase

Great

It sounds great. I had it installed and it seems to be working perfectly with the items it came with.

By Anonymous on May 5, 2019 Verified purchase

It's okay for the price

My headlights don't go down anymore with the capacitor. I didn't need to buy another battery

Regretting the purchase

Cheaply made product. Looks nice in the photo but once in hand you can that it just cheaply made . It also leaves the terminals exposed .

By Lance on December 12, 2021 Verified purchase

Good cap

I bought this cap to go along with my 2 AGM batteries and it definitely helps to stabilize the voltage during long peaks.i tried with and without the cap and like I said it did make a difference don't listen to people that say they don't work.

By Steve on October 21, 2017 Verified purchase

Decent

It's actual capacitance is probably not anywhere close to 2 farad but eh, it looks good and works as a distro block. Be wary of the allen bolts on top, they are nowhere near 5/16 so a normal ring terminal will be sloppy fitting on top.

By Brandon on April 15, 2016 Verified purchase

Great capacitor

It’s a great capacitor and has never failed. Easy installation.

By Anonymous on September 24, 2018 Verified purchase

Worth Every Penny!

The product works great!!
I can feel my subs and power is A lot more stable… Sounds more solid!

Not really sure if the display turns off after a while and comes back on when needed. Great Purchase!!!

By Donnie on September 14, 2022 Verified purchase

Believe the hype

So yes I was the typical person with diming lights when the subs would hit in short burst. I was not going to buy a big alternator and another Batt. I got this and installed it and Soo much better. I can still make em dim but the amp is rated for true 1200 RMS watts so I should got a bigger one. I will say this is alot bigger than I thought I would be. The charging method works but takes longer that you think. make sure you have ring terminals and ground wire and a ground spot. Yes the lcd turns on some times randomly and some times its not on while the sub is on.

By Les on January 1, 2022 Verified purchase

kept my headlights from dimming when radio is turned up works as advertised

By RICK on October 29, 2024 Verified purchase

Good amp

Love hifonics brand, great quality amps and this one does really well. Would have been nice with a bass knob but I guess you have to go with Brutus series for that. I’ve only used hyfonics amps for all of my car audio and will continue to stick by them!

By Michael on November 24, 2017 Verified purchase

Must have.

Had this installed. Definitely makes a difference. Would recommend.

By Matt on June 27, 2024 Verified purchase

NVX is awesome.

Great price to quality ratio. You can tell the quality of these deserve to be much more expensive once they hit You’re hands.

By Eugene on October 25, 2024 Verified purchase

Solid Product

I think this is a great product especially for the price. It does what it's supposed to and it does it well.

By Ryan on February 10, 2026 Verified purchase

Great Value Amp Wiring Kit!

The kit was great! Super budget friendly kit and easy to install. Would be good if there were more length to the wires but it's $40 some odd bucks so it's an acceptable compromise. If you want to get into a stereo kit cheap buy this kit!
