I just bought an Arc Audio 12 today (http://cgi.ebay.com/ws/eBayISAPI.dll...MEWN%3AIT&rd=1) so now I have a few needs..
Either I need a black chrome Arc Audio CXL2100 or another Arc Audio 12 (dual 2ohm) and a CXL1500-dr. I'd also consider a CXL2500.
LMK if you have any of these. Of course, the CXL2100 would be the easiest for me to buy, since it'd run my single sub and I wouldn't have to buy more stuff. Nevertheless, I'll buy around what I can get..
