I have a used, but not abused, Orion 2500D amp and a Diamond Audio D9 15" subwoofer, dual 4 ohm, for sale. Both have everything included from manufacturer and have original boxes. I also have a box for the sub that was made by vitveet over on the sounddomain forums, very nice high quality box. Make me an offer. Shipping will be $20 for both items. Going on ebay later so thought I would post here first.
