Excerpt: 008 THD (Clean)!!! This Amp more than does the job for it`s price. I also have the Alpine MRP-T406 and an Powerful Gothic Amp for my sub & Premier DEH-P880PRS, and tweeter +5.25 woofer in door, and this amp rocks real nicely! It doesn`t get too hot using 8 gage wires and always ground with the same gage as the power supply!!! For under $100.00 The Pioneer GM-X352 is one of the best in my opinion!
