Re: A full F/R components a NO NO???
Depends on the alignment of the mids and tweeters and the sound processing going on.
If you are running a straight stereo signal to the amp stage and your goal is sound quality and musical accuracy, then it's pretty pointless to be running more than just front left and right speakers and a sub stage, IMO.
I'd recommend you just focus on getting the best front stage you can for now. Run it that way for a while to get acclimated to it, then hook up some rear coaxs to the HU if you still need more. If it still sounds lacking, then by all means explore an amped rear stage.
My car came with factory Monsoon system which included front and rear comps (WTF was VW thinking???) and it sounded like pure crap. Sound stage and imaging was just not there.
I'm more than happy with the results of just front comps and a sub stage. Try it... you'll like it!
