Ive ordered from Sonic a few times and didnt have any problems either. Also if you do buy from their ebay store you can combine Bing cashback with ebates and get another 10% in cash back from your purchase.Cheaper too Boston Acoustics SPZ60 6-1/2" Component Systems Car Speakers Car Audio Car Audio, Video, & GPS Navigation - Sonic Electronix

This. Very impressed with Sonic on my purchase; fast shipping, good follow through and follow up. Plus a great deal (the PPI 355cs); Bing was 7% at the time, but still a great deal without BCB.
WoofersEtc is in Los Angeles, CA - so you can also get fast shipping in CA. With all the positive feedback for each business, It looks like you can't really go wrong with either one. It's probably just a question of which one has what you want, and maybe which one is authorized.Sonic is great, especially if you live in California, you get your stuff in days.
