ok need help lol my rear factory subwoofers dont have much sound, they work just not much sounds to them, so i bought a new sub with a build in amp so can i just cut the rca cable wires coming from the amp sub and wire them into the rear subs that are now installed in the car and then just wire the amp to the battery, i also have a plug in to use if i cant use the rca cables

 

oh man, good luck if you figure that out... have you looked up the capacitor upgrade thread yet???
