Great site! Just got back into the whole car audio thing, after 15 yrs of factory radios, guess it was about time. 2007 x-cab silverado 1 p2 punch 12 powered by a punch 500a2, alpine 6.5 components up front powered by a punch 150, alpine 4x6's in back powered by a punch 100a2, alpine 9842 head unit that will soon be replaced with a better alpine unit. Sounds pretty good want more just can't find the room will be ordering new kick panels to allow for another pair of 6.5's that I already have. Trying to figure out how to squeeze in at least one or maybe two punch p2 8's and another punch amp.
