My name is Phillip Fitzpatrick (see username). I've been doing car audio for ~ 15 years. I'm currently an active USACi competitor (0-600 and streetbeat 2 @ this time), but couldn't find the funds to do finals this year.
I've been a registered user on Caraudio.com (soundstreamer) for about 4 years and usually do my selling through there. For buying, I generally buy new. I have bought some stuff off of CA.com, but quit when I got burned by a long time user with tons of good feedback threads.
The reason I'm joining this site is because of the manufacturer specific forums (and I might jump in on a raffle or two). I hope to be helpful anytime I find a place where I can help.
