I don't think you'll like it.
Just be careful how you do it too.
My friend Josh's friend Nick incorrectly wired the harness for Josh's indash cd, he wired the power wire to the "switched" wire. Therefore, Josh always had to manually turn his stereo off when getting out of the Explorer, and could roll the windows down at any time, key or no key. The problem was that the Explorer couldnt sit for more than 3-4 days at a time without killing the battery. FINALLY I got sick of it, pulled the CD player out only to see that Nick had ghetto-rigged it, and wired HOT and switched together...
It was an easy fix. Point is, just be careful how you do it or you might wind up with a dead battery, etc..
