Customer Ratings & Reviews

NVX MAN IOWA

I bought this kit for a customer who has 2- Hifonics Amps, a BRX2000.1 & a BRX640.4, the wires were flexible & a ease to run in a 04' Monte Carlo! I was alittle concerned cause of the price but let me tell you, this price is a SUPER STEAL! We are running about 2328watts of actual power & wire is holding up great... Definitely will buy again when I need a big power wire kit! For Sure... I'm a huge NVX fan wires & all, this is great too!! NVX MAN is out!!!

ok

Not as thick as I though but it's good for my 1000 Watt amp. Have bought one for my truck 2 years ago and it seen like that one was big then this one but the same name and guage.

Works great!

Would definitely order again for someone who needs this. Easy to install works great.

Very Good Value

First, this is NOT a 3000W Rms amplifier. It's a 2136 Amplifier that can do in dynamic power up to 2810W. I did a dyno test on this amp to show the true power.

BUT, if you forget the rating and go by how this amp actually performs. its an INCREDIBLE VALUE. There is no other amp on the market that touches this amp from a cost per watt stand point.

If you are looking for a 2000W Rms amp, and don't have a lot of money to spend, this is the amp for you.

good wire

This wire is worth the money. I can't say what guage it is for sure, gut it's a full 1/2 inch or more thick and it is copper. The fuse and rca jacks are really nice also. The only thing wrong is the zip ties are so old they are brittle. Other than that, well worth it.

Excellent priduct for the price

Shopped around, Good quality heavy cable, did what i needed it to do, EXCELLENT PRICE & FAST SHIPPING!!!!! THANKS

Love it

i definately recomend this product for anyone doing a small daily driver install

Nice amp kit

The Belva 0 gauge kit is a very good buy for the money. It came with a well made fuse holder and good RCA cables.

More power

I added a second amp to my system which meant I needed an upgrade. This kit had everything I needed and good quality. Budget friendly.

Great Value

This thing puts out real power to my my 2 JL12w6, the adjustable bass boost is a great feature, I have mine set at 30 hz and just turned up maybe 4 dB and it’s really cleaned up my bass with more deep clean sound, I’ll never use another amp without this feature. This amp is just as powerful as my expensive Fosgate 1500 it replaced. I run it at 4 ohms getting 1200 Watts rms, I have a high output alternater a yellow top battery and 0 gauge wire. It’s been 2 months and so far so good I use it everyday and it gets warm but not hot, I expect it to last a while because I’m running it at 4 ohms????

GREAT!!

So this amp not only looks good, but does its job well. I'm pushing 2k-rms on this 3k-rms amp, it does get warm (not hot). I don't have any bad things to say about it. I'm happy with it, and I would tell anyone to buy the Belva BB5000Dv2!!! Oh yea the amp overall seems sturdy.

We love it!

we love it! Blew our fuses at first until we were able to get it right. Recommend!

Best deal around for $200

So I'm not gonna go and say this is the best amp ever, because the sound quality is not that of a sundown or crescendo. But that being said this amp far outperforms the power capabilities I expected and if tuned right sound really good. Just be careful with the bass boost because it will throw off your whole range of output. I am very pleased with the amp and have been in the car audio business for 17 years. I'm about to buy another. If you need a powerhouse on budget I would definitely recommend the belva.

Best Belva amplifier for your buck!

Super powerful Belva, better have your install correct! It's up a little for a 1/4 of a turn on the gain. And the other gains are calibrated. So darn powerful...

These subs POUND!

I had 2 15" Massive Audio GTX154 and switched to 2 of these 12" SUMMOXLs and they hit so freaking hard! My whole Jeep Patriot is flexing, almost afraid that the back window is going to blow out. Have them running on a 2000 watt Hifonics Brutus amp wired to 1 ohm in a ported Atrend SPL Bass box. You will not be disappointed in these subs.

Best “Bang” for your buck

You literally can’t beat this amp for this price. I’ve had many higher end amps that couldn’t perform like this

Belva BB5000Dv2 (BB5000D v2)

Great amp and it does exactly as it should if not more.

Great watts/dollar!!!

This amp makes serious power! For $199 I don't think it can be beat. Ran 4 hifonics 12's at a 2 ohm load and couldn't believe the punishment it gave those poor subs, I actually thought about running 8 of them!

Belva BB5000v2

Wasn't expecting this amp to be so powerful. I had a RF T2500.1bdcp and it sounds almost identical. The belva doesnt need as much electric power as the T2500.1bdcp.. Im glad i found this amp

Very very very pleased

These subs have a physical and auditorial presence that far exceeds any sub I have ever owned. I play them at volume 10 because everything in the car starts shaking at that point and they look good. Quality subs

Summo Thunder

I bought two of these and have been using them for the last couple of days. I'm running them on 800 watts rms wired at 4ohms and these subs are loud.

By Canetrane on February 23, 2018 Verified purchase

Awesome amp

This is an awesome amp , I have it pushing just my one 12 inch NVX V3 atm until I get another one. But over all it's an amazing amp with a lot of power

By Stephen on April 21, 2023 Verified purchase

Awesome!!!

Whewww where do I start I have four of these running them on a pure audio 3K and all I'mma say is you get what you pay for once you experience these subs it ain't no going back to anything else ???????????? wish I can add more stars

Belva BB5000 V1

Happy Customer. I've purchased from Sonic many times, and will continue to do so.
For this amount of power you will not find another amp for the same price. I bought the first version 4 years ago, and it's still slappin today. Electrical is 1awg and an extra battery, and it powers my 18" PSI lvl3 perfectly at 4ohm. I've had it powering several systems at 4, 2, and 1 ohm at it never disappoints. Just make sure you have upgraded electrical, or you'll fry the amp and your car!
If my version 1 dies somehow, I will without question buy another Belva 5k. Version 1 was $250, so you can't beat $200 for the new version.

Great product

I want to start by saying that the shipping was faster then I expected it to be and the product is “AWESOME” I am barley breaking them in and then sound amazing..... I was I little skeptical bout massive audio because I never use them but I am now a fan and want to see wat else’s there products are capable of.... I had 2 12 NVX that hit really good and hard but it was time for some new and louder and I found it.....I would definitely recommend this sub to anyone and I have not yet had any cons to say just over all a great subwoofer. Just want to thank sonic electronix for always having the best deals and fast shipping...

Excellent Amp for the price

First of all this is not a 5krms amp. It's closer 2500rms-3krms. With that said it's still an incredible value and a very solid, good sounding amp that I would highly recommend to anyone. It even came with a 300a blade fuse and carrier! I'm extremely happy with my purchase and would definitely buy a 2nd one if I needed more power. It's currently running 6 10" Sundown LCS' @1ohm daily and sounding amazing. Amp gets a little warm but not HOT. Buy this amp!


*** MANUFACTURER RESPONSE:
Your review is correct. This amplifier is advertised as 3000W RMS, not 5000W RMS. We appreciate your kind words and hope you enjoy.

Don't want it

Hey I don't want this item I just wanted see how can I just get my money back

Better than a more expensive amp I tried.

Very solid and good output @ 1 ohm on a Soundqubed HDX3 15" Subwoofer ported. Had a Wolfram C2400 and it was causing noise on fast transient music. Very pleased.

By Scott on January 10, 2020 Verified purchase

The plastic mounts???

The amps puts out power for the price. Would like to see a clipping led somewhere and the plastic feet for mounting the amp is really cheap. Three out of the four broke with only 10 minutes of play time. I had to use metal straps to hold the amp down after the plastic mounts that's on the bottom of the amp broke.

Excellent Amp for the price

You can't find a better 3000+rms amp for this price! $230 for 3k+! It definitely puts out the rated power and then some @ 4, 2 & 1ohm and sounds great doing it. Doesn't get too hot but it is by no means a "5000w" amp which I knew when I bought it. Very happy with my purchase and I highly recommend for anyone looking for an efficient 3k+ amp.

Great amp kit

It has all items needed to wire up an amp

By dusty on March 21, 2026 Verified purchase

Meh

Was cheap so expectations were low, it is extremely low quality. I would personally not recommend to anyone.
