ok heres the deal...looking to upgrade the stock speakers, nothing to crazy but i am a labol ***** and like name brands so it can get pricy. i really like JL and Rockford i have been looking at and they seem pretty good as well. roommate introed me to them the other day. so i was wondering if anyone here has upgraded the speakers w/o an amp and if it sounds good or if you did use an amp hows it sound and how much did you pay. deff something i would like to do this summer and i would like to try and do it myself so labor cost prob wouldnt be there. so anyone, any ideas would be great, thanks
