phantom express

this class d amp is the smallest most powerful amp I've ever seen or heard the truth is in this amp I own two of them in each one of my trucks need I say more.

Good bang for your buck!

These amps are solid for the price. They are a tad overrated but not by much. I think at .7 nominal it does right at rated. You may want a larger fuse than the recommended 150a for lower ohm loads. Good subtle looks and nice gain pots.

Decent power!

I would recommend this and for moderate bass lovers. I have a sun down audio 15" and it makes my doors and roof wobble! It's not ear splitting but it is satisfying! For the price I think it's pretty rad.

Yes i would !

Good Amp , i have dual 15's (NVX) and it has enough power for anything i play , i even comp with it against local friends that comp nationaly , it hits just as hard and even harder then some of them , it does kick off if it hits to low to load but any normal ranges it runs Excellent , i would recomend it .... but i think its D/C'd now which is too bad id buy another for another set of 15's ...also its a small nice looking design
