Small Amp Tons of power

The following review is for VADM1, which is a part of the bundle you are viewing.

Was really skeptical about how much power this little guy put out but it powers my one kicker perfectly and its so small you can place it anywhere if youre wanting a clean unseen install!

Great Little Amp!

The following review is for VADM1, which is a part of the bundle you are viewing.

I bought this to replace my JL 250/1 because I couldn't run a 1-ohm load on it. This amp doesn't sound as clean so I ended up hooking both up, one on each sub for a 2-ohm load. The sound quality got better and it puts out a great amount of power. It slams a kicker Comp VR 12 at 2 ohms.

Excellent shallow mount subwoofer for the money! Well done NVX!

The following review is for SMW10D4, which is a part of the bundle you are viewing.

I purchased two of these and have only tried one so far. I have the 10" version in a nicely built prefab box (currently for test purposes) that specs right about 0.81 cuft sealed. I'm currently testing it in a preexisting system in a Honda S2000. Its being powered with a 500 watt NVX VAD series amplifier. I have to say that this subwoofer has impressed me more than I expected. The sound quality is quite good for this dollar amount. I am very happy to see that NVX chose to use a rubber surround as opposed to the foam on many of their other subs. I cannot speak to longevity or durability as I haven't had them long enough to comment on that. I'm planning to install them in the spare tire location in my 2022 Veloster N. At just 3.23" deep there will be plenty of space. I hope NVX continues along this line of design for their future of subwoofers. Thank you NVX! Well done!

Tiny but powerful

The following review is for VADM1, which is a part of the bundle you are viewing.

This amp is tiny, but packs a punch, similar to the other amps in the VAD line up. The only downside is the 8 gauge power terminals and the push-in style connector for the speaker wire. The speaker wires can pretty easily pop out of the connectors on the back of the amp, and I had to use a 4 gauge to 8 gauge reducer to run adequate power and get the 500 @ 1 ohm promised on the box. Overall it's impressive that such a tiny amp can produce such power and be 1 ohm stable. It's compact design means it can be mounted virtually anywhere or easily concealed depending on what your install calls for.
