get an SSA DCON or IA I series 12 if you want new, but i suggest u get that obsidian 12 that was offered. My love mine to death, it will get down as as little as 300wrms but can take 1K all day. Get somthing like this lanzar opti drive Lanzar OPTI1400D 1300W Max Optidrive Series Monoblock Class D AmpI think more than a 12 or 15 would be way to much for how small my car is
