I'm into car audio, but I don't compete or anything. I sold most of my stuff when I got my current S10. I have a Kenwood 959 HU POS, Clarion DPX1000.2 amp, and 2 Polk subs sealed. But have been looking in to new stuff for a 06 GMC 2500HD that I hope to be getting later in 06. I stick with my POS HU until I decide if I want to upgrade to DVDs or not, DLS iridiums comps, Soundstream XTA 480.4 for the DLSs, I'll keep Clarion unless its to underpowered, and the baddest subs I can fit into a Crew Cab looking at RE XXX, Brahma, Treo SSI, Stereo Integrity Mag is looking like a winner.
