new to forum (first post) and car audio sceen as well. my factory speaker sizes are this, 3.5 front dash, 5.25 front doors and 5x7 rear. i want to stick with those speaker sizes and not get into custom stuff. i want clarity and well rounded sound in my music and not just deep bass. i have a bottom line kenwood h.u. i know i need an amp so that i can play my music louder with clarity. i'm not looking at doing anything like comps, just nice sounds for my personal taste. if i decide to drop 3.5's and just go with door and rear speakers, can i get away with a 2-channel amp? i'm not sure if i'm going with component or co. speakers. i'm looking at spending no more than $175. can someone tell me where to start and what i need to be looking for? thanks-b.
