Decent amp for the money.

I was searching for an amp to power a RE Audio SCX 10d4 which needs 450 watts rms.

This is the first amp I've purchased since about 2007 so I wasn't sure whose to choose.
Didn't want to dish out upwards of $200 for such small power.

I came across this one and decided, for the price, how bad of an amp could it be?
In 2007, I did buy some powerbass 2XL 12" subs and loved them.
So I decided to reconnect with the brand.

Very satisfied with this amp.
It powers my subwoofer well and seems to give good clean power to it.
I do I have the sub wired up to present a 2ohm load.

The low pass and subsonic are both decently accurate on the hz cutoff.

Have nothing really bad to say about it.

Runs a little on the warm side.

I'm actually surprised, given what I paid for it.
I did miss that it was a class A/B amp so I was a little shocked at the size although it still fits under the front seat of my 2008 sierra which is all I was after there.

If this amp has the power you need for your setup, I say buy it.

Good Amp

I purchased this to run a pair of PPI SN.8 subs. The power matched good for those subs and seems to work well with them. Stays pretty cool and the price was great. My only complaint is that is says "compact" but this thing is 15" long. Not a big deal.
