I use this 5 channel in my GMC Sierra 2500 extended cab PU. I have it pushing a 12" Cerwin Vega in a sealed enclosure, 2 Infinity 4x6's in the rear doors, and 2 6 1/2" separates in the doors. It is plenty of power to push to doors, but I wonder if it has enough to fully push the Cerwin Vega 12. I like the separate remote w/ punch level control as this comes I handy at times and provides a nice blue light at night. Overall I am happy with the purchase and like the convenience of one amp to push all of my speakers as it fits snugly behind the rear seat out of the way.
