So far, this has been an amp (TRQ4.800) worth it’s price, but don’t kid yourself into thinking that it is going to be spectacular or great. I’m running an Infinity PR6500cs component set on Ch1-2 and a Pioneer TSSWX2502 10" sub on 3-4 bridged. It supplies enough power to listen at moderate volumes, but you’ll need to carefully set the gain to match your receiver so you don’t blow your speakers from distortion, and not from too much power, but the opposite, not enough power. I have the gain on 1-2 set half way and for the sub slightly less. I don’t think this amp is pushing anywhere close to its rated power.
The LPF works excellent for the subwoofer and just a touch of bass boost (1/4) turn gives the sub enough kick to fill out the music. On the Ch1-2 side though, the HPF sucks. Not much audible difference between full and high. This means too many lows are making there way into the components, which can cause distortion with too much gain or too loud volume. And the other thing that ticked me off was the positive terminal screw for Ch 2 was completely stripped out.
I give it 3 stars because it does a decent job for its price. But you get what you pay for.
