SoundAdvantage said:Danny, you will need to purchase a stereo install kit for your Deville to replace the Factory deck with an aftermarket one. You can buy the kits at any Wallmart store, but you will have to look on the kit and make sure it lists the year and model of your vehicle > The kits are Universal and come with instructions. Here is a site you can go to for future reference. http://www.carstereohelp.net/wireharness.htm
Please tell me Mike where you acquired that miss information. Cadillacs have a factory amp and a tuner that you will need to intergrate/bypass,respectivley. I have a 1993 Eldorado that needed a wire harness that cost 88.95..that no wal-mart or any stereo shop in town carries.Second...the trim plate. I am not too sure on that one as i have a Eldo and not a Deville...but i am sure they are the same.and Scosche ( which is the supplier for Wal-mart) does not carry the trim plate you will need...
Every one is telling ppl to go to car stereo help, never been there nor do i care to go there..but if anyone needs to get peices for there Cadillacs then they should try out www.installer.com, if they want to go to www.metraonline.com they can which i might add is a great place.although you can't buy anything from them because they don't sell to the public. If you do some research you can find the part you need and then go to a retailer that they deal with ( Circuit City is the biggest i know of) and have them order it for you.
Hope this helps out all those who are need of correct info or for those that need correct info.
