I purchased a CJ S/S amp from them, it turned out that it wasn't a good fit for my system at that time. I inquired about trade in value, they emailed back, "why would we buy it back? If you don't like it, and aren't going to use it, send it back and we'll refund your money". 30 days after purchase. Their return policy is good as gold. You might pay a little more, but pretty much, satisfaction guaranteed.
Have made several purchases from them, haven't had a single issue.
