This amp is working suprisingly well!

I ended up with this amp as a result of an eBay auction. I got this amp, an American Legacy 100x4 (peak) amp, 2 Audiobahn 12's, and a bandpass box for $250. I thought it was a good deal. It was, to a degree.

I really don't know much about the Pyramid brand. I believe it's one of the multiple low-end brands.

I am pushing 2 Audiobahn 400W RMS subs with this amp (in stereo), and it is working very well for me.

I believe the RMS power output of this amp is around 400W RMS x2. So it's a perfect match for my subs.

No problems yet with overheating or noise with this amp. Overall, it's been a very good, low cost performer.

It comes with a remote bass-boost module that you can use to quickly turn up or down the bass. I believe it is centered around 70Hz tho, so it only modifies bass around that freq. This is pretty much standard tho.

I think this amp has some rudimentry low-pass crossovers. And a gain knob.
