OK now I don't know if my question is any different but here it goes... 2 amps 2 subs I have 2 lighting audio subs and 1 lightning audio amp and 1 alumni amp... both my subs are running 750w a piece and both my amps run 750 w a piece. Am I able to hook one amp to one speaker and the other to my other speaker... so basically 1 amp to 1 sub = 1 amp to the other sub. On my alumni amp I have line in and out can I hook from radio to line in and line out to my lightning audio amp and run one speaker to each giving it 750amp to 750 sub x2:(:(

You didn't specify whether your sub-woofers were active or passive. If active, then the power output of the amplifiers is irrelevant!

The hookup you're describing sounds OK, though I'm not sure why you'd want to do it, unless this is for an outdoor/PA setup. Indoors you're likely to permanently damage your hearing (if you run it at anywhere near maximum output), unless the subs are horribly inefficient!

Just check that both amplifiers deliver the same phase signal from their outputs. If not, reverse the phase of one sub-woofer.
