i have an 06 coupe with factory BOSE speakers.

is it true that i have to rewire everything if i'm going to install front speakers and a head unit?

and that i can't just get front speakers only, i have to get rear speakers too?

i already have a sub and an amp installed.

TIA

 

You don't have to rewire everything. You can tap into the OEM wire harness at the Bose amp. But a lot depends on whether you are adding a new amp or are just replacing the HU and plan to run it through the Bose amp.

What do you intend to do?

 

im planning on getting a DD z1, replacing the 2 front speakers and a new amp for the speakers.

 

just tap signal at the amp for your new amp...
