Budget doesn't matter as long as the quality is good and equal to the set-up I have. I want it to sound good and clear. Would like to run it off the HU if possible.
good call, amp your speakers,, i would replace the speakers with db drives platinum speakers to get the clear sound your looking for, and for the amp, u can go with db also, i really like there stuff, if not you could look into kenwood or something of that style, but i recommend db, its what i use
just replace your front components with a good set, and run an amp to them. I wouldn't even worry about the rear speakers. Just run them off the deck or put the stock front speakers in the back if they are the same size.
