Cheap kit that did it's job

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

Pretty Good for the Price

Overall, the amp is super solid and seems to be built rather well. Having a rated power certificate in the box was also helpful to see that it actually is putting out the claimed RMS power or above. Currently using it to power a single CompR 12" and it hits hard with the gain barely over 1/3 and no bass boost. Only complaint is that the power and ground inputs are not designed for bare wire, you'll need to buy a U or spade connector to reliably attach your power and ground.

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.

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.

Small and powerful

This amp is great. I have it mounted behind the backseat and it takes no room at all. It's got pre-amp and output RCA connections so I have my stereo amp getting signal. You can only use fork terminals with the connections but the connections are solid. Unlike some amps. Two speaker outputs for easier wiring if you are using 1ohm which I have two 10" Kicker DVC 4 ohm subs running at. Overall 5 out of 5 would buy again.

Great transaction

Fast transaction fast shipping love doing business with Sonic Electronix

Great transaction

Shipped from the manufacturer in a timely manner, took 3 days instead of the proposed 2 day guarantee, but overall still a great transaction.

Under rated quality amp for the price

This cx 400 is amazing! On the higher end of resistance its minimal, push a c10 or c12 but bump it down and let it go to work. 2 c10's at 300 at 2 ohm, you'll feel it knock, drop it to 1 ohm, good god, I set the sensitivity to run 500 rms, per the rated rms of 533w on kickers birth certificate, this little guy moves single p3d2-12, pounding so hard my rear view mirror shakes to the point you can it rattling the windshield. I recommend this to anyone who wants a lower total rms output or a bi-amp system (given youb match up your impedance and wattage (rms) of chosen sub. I messed up my original purchase, got a JL 12W0 crank it up and live loud

Kicker amp

This is my first kicker amp and love this product and was easy to hook up. I have had other amps and wasn't satisfied on how you had to hook the amp up because the controls you had to use an Allen wrench to loosen or tighten the controls. Kickers product a flat head or a Phillips screwdriver will work on their amps to hook it up and made it easy and fast to hook up! I would recommend this product to anyone else for a small amp that just brings the power to your subwoofer!

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.

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!

Good for the price

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

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

Great value

It came with everything I needed so the installation was a breeze

Much better than Boss kit

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

Complete kit

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

Small Form, Great Power

Purchased to power a Kicker L7T8. Easy hookup, clean power and small footprint to fit under my 2020 Tacoma driver seat.

By SDT on May 6, 2025 Verified purchase

Great power for subwoofer

Installed under passenger seat on custom ABS board, driven directly from head unit. Amazing product and service

By Scott on December 24, 2025 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

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!
