Get out your wallet.

I got a decent setup for a tad under $300... Front speakers, amp, sub, wiring.

I got a little cheaper route also that Im sure would be acceptable... All depends on budget.

So many choices can affect the overall cost that it really isn't fair to go much further without knowing: how much $s, what kind music, how loud?

Best place to begin is replacing the front 4"x6" speakers, even the stock HU will sound a lot better. Anything more is wiser to plan for... Let us know cause spending other peoples money is almost as fun as shoppin for myself.

i'll back Nate up, his stock system is crystal clear, sounds amazing.

now i matched up every wire on there to the harness on the new stereo, except that i cannot find the class 2 data cable, id like to get this up and going and i dont feel like paying somebody to do it lol.

any help it greatly appreciated, thanks guys

i have the same car and wut ive read and been told it the only way to put in the new head unit if with the special bypass box because of the data bus run through the head unit i had to buy this box setup, a wire harness, and an antenna adapter to put in the head unit and if you get a new headunit your going to want new speakers if you dont already have them idk if this helps at all but ya usually u need a wire harness in most cars ive needed a harness for the 5 cars ive done because cutting off the factory adapter wasnt a goos idea for me

The only issue you'll find is a loss of the chimes.. like if you leave your headlights on and such.

I never lost my chimes

is there any way i can put the stock connector back on that i chopped off, so i can plug in the wiring harness? i know this is probably a stupid question, i just dont know how to do it, i cant seem to get the little pices of wire out of the connector. could i buy another one at canadian tire or something?

thanks :P

um just reverse what you cut off....connect the same colors together and it will work good as new.

I dont know if you have junk yards up in cold north country, but if you can find one cut off more wire from a junk yard car and splice it onto your car..
If not, then you can get a pigtail from the dealer.

Oh if you can take a pic's when your done....
