NVX VADM1 500W RMS Class D Monoblock Car/Marine/Powersports Micro Amplifier with Bass Remote

Made crazy waves in the neighborhood for the price haha, I did have some trouble with setting it up but I absolutely chalk it up to user error. Nice sleek finish, neat little remote knob, only gone into protection mode once when playing a certain song on full volume so I'd say it can withstand a lot. Improved my cars sound system quality by 1000x.

Using this amp to drive 2 Rockwood K9 6.5 sub-woofers wired to 1 ohm on my boat. Sound amazing and puts out good power. The only complaint I have about the amp is the mounting screws on the bracket on the power side are horribly placed. Not possible to screw in without removing the bracket from the amp first which is a poor design and tedious. Not to mention very difficult in the small place that I mounted the amp in. I managed to pre-run the wires through the bracket on the one end and mount the bracket then screw the bracket back on to the amp. Not recommended to do with the wires being live connected to the battery though as would be easy to create a short since the bracket is metal. Other than that I absolutely love the power and size of the amp. I would definitely recommend to anyone. Just hope the improve the mounting bracket on next version. Does get a little warm to the touch after a while on full volume , but not super hot.

Pros: Small form factor, lots of power for the size Install notes: the speaker wire terminals were not intuitive, and I nearly stripped them out trying to figure out how to get the wire in there. The install was a while ago, so i dont remember what it was, but it was something like they were all the way out from factory, or all the way in, either way when i turned them i was turning them the wrong way. You also have to remove the end-piece bezel in order to get access to the terminal screws as it overlaps just enough to make it not accessible. Seems like a design flaw to me. Cons: The unit lasted about 3 months until it toasted my subwoofer. I had this powering the Toyota Prius 10" NVX subwoofer, which is notoriously poor quality, so I assumed that it was the subwoofer that died. I replaced it with a high-quality JBL sub from Crutchfield, and the first power-on toasted that as well! I hooked up a voltmeter to the speaker wires and sure enough, this amplifier is sending 12.4 volts directly to the speaker at all times. The "Fault mode" indicator is reading normal, no fuses blown, the internals of the am seem to be totally out of sorts, as even without any signal passing through the amp its sending a constant 12.4 volt to the speaker wires.

Good little amp. Make sure you have a rock solid ground or it will not work. Thought I had a good ground through the seat bolts (ground them down and sand papered) but nope. Had to go right to the frame before this little guy would start to work for me.

This thing is tiny! Using it in a RZR. It work well with a sub.
