Okay, so i'm getting ready to setup my carputer in my 93 escort. But I think the right speaker setup on the headunit isnt working because i just replaced the speakers and it still didn't work. So am i better off buying a new head unit, or a 4 channel amp? this the amp I am looking at

If i did the amp, would i get a 5.1 card and connect the front and rear to the amp and then the sub output to my sub amp? Or will that not work since its 5.1?
