i buy everything off ebay. Look for a power seller with a good rating and positive feedback. U can't go wrong with the prices! ive bought about 30 car audio items and it was quick and easy every time! its the best IMO
everything that i bought online is either from ebay, the manufacturer themselves or an individual via paypal. IF you are looking to buy car audio stuff then check out the following sites: ebay.com woofersetc.com soniceletronix.com millionbuy.com you won't have any problems with these sites.
