good point there. But back to alpine i have had their decks,amps,subs,everything and i didnt like it at all. The HU blew out the RCA's, the amp smoked causing the subs to tweek and blow so i said f' it and went with a kenwood/pioneer system that i liked alot. But the best setup for me so far has been a kenwood HU,KIcker amps and x-over,2 12"Kicker comps and mempis highs and mids. That sounded great hit hard and loud and had good sound quality.
