I just put an Boston Acoustics Pro Series 12.5 in my 80 series. Wow! It is the BOMB! So now I want MORE. Has anyone put the Boston Pro Comp 6.5 speakers in the front doors? How about the back doors? I want a system that will make my ears BLEED. It is clear now with 5.25 Kenwood Exeleron speakers in front, and 4 inch memphis speakers in the rear. I'm running a memphis amp that sends 250w rms to the 12.5 (its a 500w monoblock) and another memphis that I think can send 150w rms to the other four speakers. Sorry if this seems juvenile, but I love music I can feel. Which is what I'll need if I keep this up as I'll be deaf.
