I just bought this amp on ebay about a week ago. The only reason I am selling it is because I need an amp w/ bandpass x-over capabilities. It is a refurb and cosmetically does not look all that good but works great. This amp will do 175x2 at 4ohms and 500x1 at 4ohms. I can send pics to whoever is interested. As for my references, I bought a Clarion HX-D10+DPH910 from doggboy on ECA and I also bought a 3 way Type X component set from HiAmplidude on this forum. Looking to get 100 shipped.
