I have an 04 as well, and i would like to do the same thing, i dont like the look of aftermarket simply because thats when people start peeking their heads in your car, and shit gets jacked, so i dont want to do that. i have 2 12' subs and a 1000 watt amp already, i had that installed at Mobile 1 (sp?) so i knew it was installed right, and if i had the money would go back, but again i dont want to have an aftermarket head unit. do you know if its possible to just get like an aux - headphone jack and wire something through the XM box???
