And thats why you dont go to best buy for proper stereo advice. Obviously a retail store like that is going to make you think you need to pay more so you'll spend more money at their store. But anyways now that I've spoken my opinion:rolleyes: , IMO installing a new deck (headunit) involves a wiring harness and an installation frame based on the original radio's DIN or relative size of the radio opening. (What kind of car do you have anyways) ? Heres an example of an installation frame http://www.cardomain.com/item/SCOGM1517B (which as you may notice isn't 200 bucks.) I dont know what kit he's looking at. As well as that, Youll need a wiring harness because the back of the new headunites accepts a single harness, These simple attach to your factory bits and then to the new unit. They usually include all the speaker, power, and input wires. http://www.cardomain.com/item/SCOGM03B This is a cheap one, not that expensive at all. And finally as for wiring youll need this http://www.cardomain.com/item/SCOMDA1B which adapts your antenna connection to the new head unit. As for the speakers, you dont need to change them at all unless you want to. Depending on your factory amp, which in cadillacs especially with bose systems ARENT THAT BAD IMO for a stock amp, you wont need to do anything to the speakers. All that a stock amp means is that you may not be able to get the full power potential out of the new headunit. Understandable right? Heres a descent unit http://www.cardomain.com/item/JENCD3010X and youll notice that it has about 25 rms watts per 4 speakers. Your stock handles less power, this is the reason why he said you "had" to replace your speakers. The only reason you would NEED to is if you really pushed the power in your stock amp with the new unit, hence more power to the weak speakers. And bam, you got yourself a blowout in that case. But with a stock amp (which is most likely tuned to your stock speakers) I doubt you'll need to worry about speakers blowing because the amp won't even be able to push enough power to them.

lol, wow i guess u werent finished, i was like what the....i missed all that!? anyways thanks a lot for the input and it makes a lot more sense now. i think they were pretty much charging me for the labor of installing the deck. he said i needed new speakers but he was probably wrong. i will probably have a lot more questions but thank you for all the help.

You dont need new speakers because even with the potentially more push from the new headunit, The stock amp is not capable of using that push anyways, It has it's own limit no matter what headunit you put in. So unless you get a new amp, don't worry about the speakers

Do a search for other stereo posts there are a lot of them around here with a lot of good information.

If you have the Bose stereo I think you do need to change the speakers if you change the radio but like I said do a search and you'll probably find something out about it.

the only reason you would need to change the amp is if you wanted more power unless there was some mishap with wire harness compatibility.

yah a lot of people told me if they were bose speakers, i need to replace them, could i cut the adapter off and crimp on a compatible one? or would that not work.

if you do however theres a positive and negative terminal on the speaker, its probly best to add like a terminal to the old wires such as a spade connector or whatever may work with the new speaker instead of direct wire ext. Its just cleaner and more contact. Plus it looks better, because ya know so many people are gonna be looking inside the dash are your wire connections ;)
