If you live in SoCal the best place by far is downtown LA. There is literally one whole street with both sides lined with stereo shops. Most of the items are last years stuff but great deals!! I picked up my Alpine head unit with Bluetooth, JL audio 6 channel amp and 3 pairs of infinity 3 way 6x9's and all the wire, antenna ect... For $400. The 6x9's at bestbuy were more than $400 for 3 pair. I will post the address if anyone is interested so you can map it.
It's down by the fashion district and its kinda like little TJ but the stuff is cheap and it works good. I can clearly hear my radio while at WOT and I still have money for gas.
