Hello all. I have a 2001 Civic EX sedan. I listen to a lot of music and would like to be able to actually enjoy it. I know a little about car audio but not very much. I would like a little cleaner sounds and better bass. My budget is not very big: around $1000 or less if possible. I assume I would need a new headunit, new speakers in the front door and the rear deck. Would those be enough for decent bass or would I definitely need a sub in the trunk with amp? I don't know about specs of speakers or what brands are the best. I just started looking at Crutchfield for some ideas. Any help would be much appreciated.
