I am looking for a good subwoofer amplifier myself. If you guys do go ahead and make a 2 channel amp, please make sure its bridgable and don't put all that crossover crap on it. I wanna do a servo feedback and throwing crossovers in there dorks around with the phase not to mention having like 16 Hz highpasses when the speaker will go down to 10 Hz. I have had problems when the output phase isn't about 0 degrees with the input phase. So try and make sure it doesn't mess up the phase also!!! <:
