I had my Phoenix Gold 1000 watt amp and my Cleansweep put in this weekend by Romancito104. I installed 4 Polk Audio Momo speakers myself. He mounted the Cleansweep behind the glove box in such a way that it's difficult to see even with the glovebox door off. The amp was mounted to the back of the seat with the wiring running through the seat back and down toward the right side channel. It's very clean with little cutting. The sound is very clear even pumped up.
I'd highly recommend Roman if you're looking to get some work done in the San Diego area.
