I have a pair of Alpine Type R's in my front doors, and two pairs of Infiniti Kappas one in the rear doors and one going to be put in the rear deck. I also just bought a four channel Audiobahn amp that I'm going to use to power the Kappas, while leaving the Apline's powered off the radio. My question is should I switch the Kappas into the front doors and put the Alpines in the rear deck to round out the sound? I don't know that if I put the Kappas in the rear deck if that will be too loud in back and not enough up front. Anyone ever try this at all? Thanks
