I have a 02 Jeep Grand Cherokee. Previous owner replaced stereo with alpine head. 2 1/2" speakers in dashboard are blown. There are no additional amps beyond the in-dash alpine unit. There is no sub.
1 - I disabled the 2 1/2" dash speakers so they don't rattle. The front door speakers don't seem to be as loud as the rear door speakers. Could it be that a crossover limits the front door speakers and sends much of the signal to the dash? Or is it more likely that the dash speakers and the front door speakers both get the same signal? Do you think dash speakers are important to overall sound, or would good door speakers be enough?
2 - System lacks any punch. Son thinks it needs a sub. Best Buy believes it needs a better head unit. Should I invest in sub or replace Alpine? With what? I don't like the idea of losing cargo area to put sub in.
