US Acoustics is not the best in the world, but they are not the worst either. That 450 watt rating is not going to be a true power rating. It is more than likely just its max power rating. You can probably expect about 200-225 watts true power or RMS out of that amp. 200-225 watts should be plenty depending on what type of sub you are running off of it.

Its okkk... my dad had a couple to power his component speakers. Their not really good for powering subs tho. They are good if you wanna buy something decent for a low price...

I'd spend money on a bazooka and have a good sub.

That amp should be fine for your one 12. Plenty of power there....not the best on the market, but it should not dissapoint you.

my friend had a older model 2150 in his car for quite some time powering 2 Cerwin vega DVC 12s it really pounded and the amp never failed. i would get one if i found a good deal on one
