Sonic Electronix has some good deals but the only drawback is that you don't get the manufacturer's warranty, you get their warranty which is always much less. If the uniy fails then you must send it back to them, not Pioneer. That happened to me when I purchased two Rockford Fosgate amps from them. One was defective and I had to send it back to them. They had to repair it which took over three weeks plus I had to pay shipping both ways.
