I have a DD cm-600 amp and a JL Audio 500/1 amp for trade. Both work great and have scratches on them. The DD amp has a plexi glass back on it and the JL is original. I can send pics through e-mail or text 318 344 4781. I know it would be easier for everyone else to just see them on here but I am new to the site and don't know how to upload. Only interested in a skar audio sk 1500 amp thanks guys
