Good product at a fair price but the total lack of tech support was VERY DISAPPOINTING! I won't be buying from Big Jeff Online again for that reason. I'll buy from someone that knows what they're selling and how to give customer support! The 3 stars are for the product, not for the seller, which there was a way to give Rockford Fosgate a 5 star and Big Jeff something way less.
