Introducing the VADM4

An Unbelievable Amount of Power for its Compact Size

Introducing the new VAD M-line of amplifiers. This new line of revolutionarily compact and surprisingly powerful amps will blow you away. This specific VADM4 amplifier has a total RMS power output of 400W all in a chassis not much larger than a dollar bill.


Big Power From A Small Body

Introducing the NVX VAD M-line - the smallest amplifiers in the VAD Series - but don't let their size fool you, this amplifier is capable of sending up to 400W of true RMS power to four speaker locations. Not half bad for an amp roughly the size of a dollar bill.



Water & Weather Resistant

The VAD M-Line includes a conformally coated, marine grade circuit board. This allows this amplifier to be installed in nearly any application. They are great for any car, motorcycle, ATV, UTV, or boat.


CEA-2006 Compliant Class-D Amplifier

Class-D amplifiers like the NVX VAD Line of amplifiers are more efficient, produce less heat, and draw less current than traditional Class AB circuitry.

3-Way Protection Circuitry

All amplifiers in this line are designed with built-in 3-way protection circuitry. This will protect your amplifier and your speakers by offering a number of different protections including thermal, overload, and speaker short protection. These protections will help ensure the longevity of the amplifier and your system as a whole.

Great Backfill

The following review is for NSP525, which is a part of the bundle you are viewing.

I purchased these to use as backfill in my NVX system and I am pleased to report that they have met my expectations to a T. They are plenty clear, and handle the power I am throwing at them very well. Like most speakers of this size and design they are limited by how much bass they can produce, but for rear fill in a system they are perfect. My kids say this is a huge improvement over the Bose speakers they replaced.

Great little amp.

The following review is for VADM4, which is a part of the bundle you are viewing.

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.

Powerful little monster

The following review is for VADM4, which is a part of the bundle you are viewing.

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.

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

The following review is for VADM4, which is a part of the bundle you are viewing.

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!

Perfect for classic cars

The following review is for VADM4, which is a part of the bundle you are viewing.

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.

Awesome little amp!

The following review is for VADM4, which is a part of the bundle you are viewing.

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.

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.
