Cheap

I tried to return this because it was cutting in and out on the front channel. They sent it right back to me the same day they received it and said it was fine. There is a loose connection inside and the face plate moves. If the plate is in the correct position the amp works fine. But if it moves just a fraction of an inch, the front channel shuts off. I had it checked out and ended up having to make a small gasket to wedge between the face plate and the switch to keep pressure on it so the connection would stay and now that has failed.

Sonic electronics wouldn't do anything about it and it's passed return/exchange date (which they wouldn't let me do the first time anyway... I asked to exchange for a different brand)

Get a different brand from the start. I chose this one because it had some good reviews but it seems if you happen to get a lemon, you're screwed. Not worth the gamble to me in the future.

Powerful little monster

Purchased this amp on a whim. I tried looking for more reviews before dropping the coin, but couldn't find any on other sites. After receiving the amp and installing it, all I can say is my door speakers sound WAY better than being run off of deck power. I initially had a set of Kenwood KFC-P710PS components in the front, Kenwood Excelon KFC-X174 coax's in the rear running off of a Sony MEX-XB120BT. With the speakers now being powered by the NVX-VADM4 amp they are much more detailed and louder. I didn't think that such a small amp would be able to deliver enough power to make them sound as good as they do now. If you have a vehicle with confined space or just don't want a huge amp taking up room I would definitely recommend the NVX-VADM4. It's one badass product.

Great little amp.

I have purchased 3 of these amps and will continue to buy them for different applications on motorcycles. In the bridged mode, they provide the perfect amount of power to 6x9 speakers in lids. They have superior sound quality in either standard setup or bridged. No worries of overheating. Two of them will sit side by side in a Harley fairing and provide ample power to any 4-6 speaker setup providing 110+ db of clear sound that can be heard at ANY speed on a motorcycle. Nvx has done their homework on this little amp.

Perfect for classic cars

Loud cars need loud stereos, and this little gem gets the job done. I have this in my 1972 Duster mounted on the firewall running a pair of JBL Stadium GTO930s and a pair of Cerwin Vega H746s, and it sounds amazing. It's small enough to hide just about anywhere and packs plenty of power. I highly recomend this to anyone with classic cars who wants to keep their system hidden.

Great Experience

This a great product. I bought this for my 2016 Roadglide. It's surprising how powerful this amp is. The sound is crisp and clear. Travis was a great help with choosing the right amp.

Snap NVX Done It Again

Had the mvpa4 upon release. Perfect size for my bike. Finally went to upgrade speakers and everything. Upon opening the box for the amp it fell right into a puddle from my lap. Upon looking I found theyre now marine rated! Also very minimal Scratching! New power availabilty is going to power everything nicely!

GREAT AMP

Have ordered this amp for several Motorcycle setups. Runs cool and plenty of clean power. Also small enough to fit into the fairing.

Awesome little amp!

Using this simply to allow running all 8 speaker locations in a 2012 4runner. Simple to set-up gets hot, but doesn't seem to be a problem.
I've got 6 nvx door speakers and a pair of pioneer 3" in the dash. 2ohm on all 4 channels still sounds great.

Excellent amp

The size is tiny, power is amazing i'm powering a JL W0 10 and JL components , the gain isn't even up. Nice space saver and it's just as big as my Iphone XR. It exceeds my expectations . Will buy again.
