x2 on the diamond audio amps.. Never ran them but very good from what i hear.. the 1000.1 or the 1500.1get 2 idmaxs and a Diamond Audio D61000.1
the idmaxs will fun you about 650-700 on the net brand new. the 1000.1 will run you about 450. all way way better then the audiobahn crap. the idmax will give you really good sq too.
