Audio Upgrade Help
Can anyone recommend an audio shop or installer who is well versed in BMW audio around OC? For legit audio recommendations, I don't mind traveling to the IE, LA, or SD, etc.
I specifically need someone who knows their way around the stock "S688 Harman/Kardon Surround Sound system".
Thanks in advance!
