Well i would run the 4 channel amp to your door speakers then use the other amp in stereo mode and bridge your sub, so yes you should run both amps. Seems like the best way to go about doing it.

thanks for the help. is there a better place to mount them? they are to big to hide behind a pannel.the 4 channel has a built in eq.

i dont have room to mount both amps under back seat.which amp should i use 4 channel or 4-3-2 channel i am thinking the 4/3/2 specs say 1 channel = 75watts
1 channel=175 watts 1 channel =250

if you have four speakers then use 4 channels.. one to each speakers.. if you have 2 then use 2... just use number of channel that equals to how many speakers u have.. otherwise u have more than 4, u might need another amp.. for any1, correct me if i m wrong.. good luck
