Has anyone changed the door speakers in the base model with the 4 speaker setup? I put an Eclipse CD5444 head unit in last week and am now looking into new speakers. I guess I am trying to decide on 5 x 7 coaxials or going with 5 1/4 components. Over time, I will have new speakers, a single 5 channel amp or a pair of amps and a sub. Probably in the Scosche custom enclosure. Any advice or opinions? Thanks.
