Help quick! 4 Channel > 2 Channel?

[zmoz]

I need to get a new stereo for my jeep. I'm looking at a few that are 180 watt...4 channel x 45 watts. Eventually I want to get a seperate amp for the back speakers...if I did that, would it be possible to hook up the stereo so that it is only controlling the front speakers, or 2x90 watt?

I have a 4 x50 watt amplifier in my Jeep....you can hook up the front for now and wire in the back later

But will it then be 2x90 watts?
