dude it's tricky because there is a factory amp in the rear that also has the crossover system for the 10 factory speakers. the speakers in it are pretty good already imo it's just the amp that sucks... you can bypass it if you know what you are doing. i haven't done it yet my head unit still runs through the amp it's fine for now... i would try to get that setup first either that or completely redo all the wiring and put in your own crossovers.
