i think i may still have 1 Mtx Blue Thunder 150x2 which puts out a max of 420 watts and also may still have Mtx Blue Thunder 400x5 ....last time i tried to hook them up, they didnt work... all 3 amps would cut on and off, on and off....dont know if it was all 3 amps being bad or something else.....after i took the amps out, my HU started to do the same thing... but u can have them for 50$ if intrested...
