For anyone looking for a great 2 channel amp, I got this BLAUPUNKT PA2150 2 channel amp for under $100 off of Ebay. It's a class D amp & doesn't generate alot of heat. It's rated at 150X2 RMS, but the build sheet that came with it that tests the output has it a 178 per channel. Bridged mono output is tested at 489W! I got it to run my sub in my Explorer. It sounds just great too.
