Three Subs

I have two 12 inch pioneer champions that are powered by a 2700 watt amp. I am buying another one and am wondering how to wire the whole set-up. I know I need a new box and another amp. But my question is how should I wire it with two different amps?

Are the amps 2 channel, 4 channel or mono

going from 2 subs to 3 subs of the same type and size will not net much extra output and make getting the right amp load very difficult.

Its a 2700 watt amp that is 2 channel but can be bridged into 4 channel. I just bought a 1000 watt kenwood amp. Its 2 channel and can be bridged into 4 channel. Should i get rid of the 2700 watt amp and get two smaller 1200 watt amps or what?

???? bridging will REDUCE te number of channels, not increase

What is the amps RMS rating

I dont plan on bridging them. The RMS on the 2700 watt amp is 1300 RMS. And the 1000 watt amp is 500 RMS.

Right and whats the RMS of the subs you have? How many Ohms is each sub?

They are 4 ohms and 800 watt rms each
