"Can you PM me or post up their email address? I might have them work their magic so I can run a double din. "

Sure, 1.619.444.2021 is their phone number, 1225 Broadway. El Cajon, CA, 92021 is their address.
El Cajon City – Classic Sounds is their website. They have 5 locations.

I am warning you though, working with them was far from stress free, they fought me over the paint and kept trying to charge me more for it (because they kept messing it up) Once they realized they werent going to get it right, they sent it to a real custom paint shop and tried to charge me for the external charges of the new painter. I had to stand my ground pretty hard. Other than the paint, they did everything else in house and did a really good job. Just have your wits about you as with any "custom shop."
