wireing 2 amps together so that their wattage is combined

[bnichols04]

I have a 200 watt amp (small) and a 700 watt amp (big)

I have the small amp on the door speakers and the big amp on the sub. I want to just have the door speakers run off the radio and have both amps push the sub.

I need a wireing diagram that can show me how to do this or have someone walk me through it.

The big amp has 2 sets of rca's and the small amp only has one. (If that helps anny)

Can't do it - I asked this question before and was told it won't work.
The only way this could work is if you can bridge the 2 amps together and only certain amps can do this.
