My Crunch amp. im in love

When I first got it I was a little skeptic that this amp would handle with what I was about to put it through. And 2000 watts RMS on bridge its incredible for the price, main you I have to it 4 8 inch Audiopipes mid bass 250 watts rms and two selenium loud trumpets the speakers cant handle the power I had to lower the gain on this amp to almost minim in because of its output professionally installed and its just leaving people impress and death of the ears lol I love this amp and I plan to purchase a another one to complete my set up. I highly recommend this amp.
