I have been playing around with what I want to do for my sound system. I have an 04 Grand Cherokee Laredo. I am about to begin fiberglassing new door panels and I think I'm going to keep the stock 6x9's that are in the door and I would like to add an Alpine SPS-609 (85 watt RMS) in each door so that there are two 6x9's in each door. I also have a Jensen Power 760 amp that puts out 75 watts rms x 4 @ 4 ohms. My only question is what would be the best (and most cost effective) way to power and wire all these speakers. I want loud with rather decent sound quality. I want to do these before I put in subs. Any ideas guys?
