Not sure where you're in the Bay Area, but I would recommend Street Beat in Hayward if you're thinking about doing a stereo upgrade. They also install alarm, and from what I've seen, it's excellent also.
Looking for a shop that has done the ADS to basic suspension conversion. Can't stomach the $4K+ cost at the dealership to replace the ADS. Has anyone in the SF Bay Area had a good experience with a local mechanic for this job? Thanks.
