i wanna daisy chain my amp with another amp to power my speakers.. do i need to run a another set of power, ground and remote wires? if i do i figured i could just wire it into the amp thats already in my car now.. is that a good idea or would it mess anything up? would just wiring the remote to the other amp mess anything up? would having more than one power wire on the positive side of the battery mess anything up? im just trying to find an easy way to do it so i dont have to run alot of new wire thru the passenger compartment

amp already in car - rockford P2002..
amp i want to daisy-chain - coustics 350u
