Can anybody recommend a great car audio store in the San Francisco Bay Area? Especially one familiar with working on late model pickup trucks, but who won't blow you off if you want to keep the stocker 6-disc in dash headunit. All the stereo stores I've gone to recently (Good Guys, Circuit City, Motor Music) are very familiar with Accords and Beemers, but their knowledge is 100% theoretical when it comes to Ford F-250 SCabs. If you had a referral, that would be excellent. I know they must be out there.
