alright check it out, i have a 2000 audi A4 1.8TQ with the bose stereo system. i have been without my rear deck speakers for a long time now, they blew, so i unplugged them. my front speakers are starting to go now. i am getting ready to purchase an aftermarket HU, specifically the Pioneer AVIC-Z110BT.

My question is what is it going to take to overhaul my stereo system?? can i just simply buy new speakers with the new the Pioneer HU and everything will be hunky dorey? or am i going to have to bypass the amp? or will i have to replace the amp?

What i want overall out this, is all brand new speakers that are going to work flawlessly with the new HU.

All help is GREATLY appreciated.
Thanks
