I am trying to setup a sound system for my vehicle and am looking for some advice. I am using a very small vehicle so am going for a pretty reserved setup. So far, I plan on upgrading the head unit, putting 4” mid drivers in the front doors, super tweeters and 5.25” co axial speakers in the rear panels (it’s a two door vehicle), and lastly, a compact active subwoofer under the drivers seat (I love bass heavy hip hop). I am wondering if the coaxials in the back are unnecessary and if I should go for a two speaker setup, or lose the components all together and just use 4 co axials. Any thoughts ?
