I allready have an MP3 headunit, andf from what I can see, the BOSE amp uses a line level out from the Headunit. My Head unit has a line level out.
I know that there is a lot to change, but I have a small baby, so have a large pram in teh boot most of the time. And despite the boot being the size of a small nation, it is still full, thus leaving me no room for a sub. Hence why I sold it.
So am looking at the Bose setup, to give a bit more to the sound, and keeping things standard.
One other question; Are the door speakers different in the Bose setup, or are they the same as the standard ones. If they are different, does anyone know what rating the uprated ones are, as it may be easier to source an aftermarket alternative.
