I went ahead and ordered the door speakers, door wiring harnesses, door mount adapters and foam rings, and the (not for current use) interface. That way in the meantime I can enjoy the upgraded speakers on the current setup. I may wait on the rest and follow along with your progress. Kicked around the idea of a dsp with more channels to add rear speakers in the cubbies as well, but that would require a bigger (or two) amp, and would require my car to have a different “tune” on the dsp. Plus, while I wouldn’t be concerned about putting subs behind the seats, I’m afraid I may end up with a distorted sound if I put mids back there. Tweeters could be mounted behind the headrests and powered down, but facing the mids at the back of the seat certainly isn’t ideal... @XtremeRevolution have you heard anything about the sub enclosures? Would certainly be easier than fabbing my own, but I have done it in the past for my SPL competition vehicles, so I suppose I could if necessary.
