I have a 91 Jeep Cherokee with some bad infinity speakers in it right now. I am upgrading to a Jensen Power 760 amp and four Alpine SPS-609 speakers. How will this sound. My headunit is an innovatek. Should i place two of the speakers in the rear doors or in the very back trunk door where the speakers are currently. I also plan on upgrading to an Alpine SWR-1222D 12" sub with a Jensen JPA600D amp to power it eventually. I'll most likely put this in a ported box in the back. How will my system sound with and without the sub. What else should I add. Will my system be worth the money? My biggest question is the placement of the speakers. Thanks.
