they seem to have the lowest prices i've seen: my guess is they somehow give you wholesale prices. they told me they had both models i wanted in stock, then sent me only the cheaper 6.5's, but put the 6x9's on back order. though they lied, they DID give me a refund on the backordered speakers.
This amp is what i want, but that price just seems to good to be true. just look at the savings.
