honestly, those 2 arc audio amps that gvp has would suit you well. the xxk1500 will give you your rated 1000rms on both d4 and d2 versions of the l7-15, so it doesn't matter which you get, and the other should power most mids nicely, plus they match well. ps. he posted in your "wtb4hannel amp" thread.......
if not, i do have a rf t5001bd birthed at something like 1160@1ohm (don't have the origional birthsheet, but that is what they run, and should match a d2 l715 just fine)
