How do i bridge two diffrent amps?

Question

one is 2000watts for the subs and another is 600 for the speakers.

Answer 1

No, they have to be matched before you can bridge.

But you are connecting one only for the subwoofers, and the other for the midrange and tweeters, so you are not bridging.

Bridging is connecting the outputs of two amps together with the lows outputs tied together and the speaker tied between the two high outputs. The inputs to the amps have to be tied together, but one of the amps has to have a phase inversion. The amps have to be matched in gain and frequency response and power. You do this to get more power into a speaker.

Answer 2

when puting in the out put on the 600 watt twistin the input wire of the 2000 watt amp
