Very, very good custom shop located on 521.
Did my install, which, given, was very simple, but they are also doing SeanDub's and my cousin's (not on CarAudio). Really, check them out before you pay more at another store. They really know their stuff.
They have a fair inventory, but can order whatever you want, obviously. They won't try to screw you over, even if you have no idea what you are doing.
They advertise and are a full custom shop. They do: tint, alarm, remote start, wheels, headlights, whatever. However, their real focus and money maker is the audio.
The owner and staff are really nice, down-to-earth guys.
Really, check them out.
