i think as long as you do a good job of cutting the dash i don't see a problem with it..... my dad and i cut the dash i mean its just 2 little pieces that you have to get rid of..... i had a jensen CD player in the dash but ended up taking it out hopefully soon im gonna have my pioneer premier in there.... and in all reality if it looks good i don't see a problem with it ya know plus i have 6x9 in the package tray i am putting a 12'' sub in the back( which i won't really be able to hear over my exhaust) but it sounds good and i have some old door panels that i am experimenting with but what i am attempting to do is cut the back of the door panel off.... the cardboard piece and slide the speakers in under the original vinyl cover that way you would never be able to tell they are there unless you look very close... ill let you all know how that works out when i finish
