You can do that, and it'll work.. there's just no point. You're not going to get any extra power by running the rca out from one amp to the rca in of another amp. You're just passing the line level signal through the first amp onto the second. If you want to run two amps on one sub, you need a DVC subwoofer.. And you need to match the gains on the amps.

I'm with BigMike on this one ... Based on your diagram, there is no point in having that first amp in the loop, as it is powering nothing. If you intend to run OTHER speakers off that first amp, then that would be the way to do it ... 2¢
