Easiest way and lowest cost is to go with aftermarket system. You can go to wal mart and get a wiring adapter that plugs into stock harness and allows you to spile open end into wiring on new radio cd deck. About 10 bucks also pick up the 15 buck adapter kit to mount radio solid and correct. Any number of good after market systems are available from JVC(wal mart) for under 100 bucks or go 150 and get base line Alpine, great for expanding. If your kid love loud music like me get one with at least one set of preamp out put RCA plugs for adding a sub woofer. Door and back filler speakers can be run right off unit or with speaker wires amplified to match the sub. This is all in the line of upgrading as you go along. If you need any help wiring or mounting unit and speakers email me I will be glad to help. I am a electronics tech and have installed stereos in all my cars and trucks and many friends. It can seem complicated but it is easy if explained correctly. This is if you are not already familiar with car stereos. My email is
