Is it true that the only way to install a aftermarket cd deck is to change out all the stock speakers?
or is circuit city bs... ing me?

 

It can be done without completely replacing everything. The only drawback is that you won't gain much in sound quality by only swapping out the factory deck. The entire factory system is very poor and only replacing part of it won't gain you a whole lot.

 

im not worried about gaining to much my factory deck doesnt play cds anymore, thats why i was asking.

 

Which sound system did you get from the factory?

 

an aftermarket head unit sounds great with stock Bose or Monsoon speakers (better with Bose IMO) Of course you'd get better sound from aftermarket speakers; well most of them...

 

I got the bose I have an LT1 car

 

You don't need to take out the speakers themselvs, but you'll need to get in there and remove the amps in each of the front speakers. This way you'll be able to run an aftermarket HU with your stock speakers...
