DO NOT go to auto symphony (on Van Ness). they are a horror story, and i can sum up my experience there in one number: $2500 (the amount they cost me by screwing up my car's wiring on my previous stereo and refusing to fix it)

SF Honda was recommended to me so i went there for my Empeg install. but the minimum wage dork that did the install managed somehow to not figure out how to connect the (clearly labeled) front/back, left/right RCA hookups and the fact that the amp rca was plugged into a speaker out. took me 2 minutes to fix but i can't recommend anyone who can't bother to test it.

there is one company in the bay area - the autophile (www.theautophile.com) - they are absolutely the best (they work on cars for audio competitions, etc.) but they are pretty expensive. for example, one install option is a soundproofing foam they can spray into your hollow doorframe to muffle the echoes.
