Good value extremely hot

This is a very good amp. The size is super compact and you could fit it just about anywhere. I have mine installed in the spare tire well of my Honda Civic.So as many have mentioned the stamp is extremely hot. It will literally melt plastic that comes into contact with it and willburn you.For those of you installing it in a car you can remove the side panels and use a 12-volt squirrel cage fan to blow air through it. That's what I've done to keep it from melting down.

works well

very nice, easy, decent price

All the power you need in the size of a deck of cards....

Plenty of headroom, and should meet any normal needs.


Great product
