Hi,

I installed a BOSE rear speaker system to a non-Bose amp and put a lot of my findings here: Bose Upgrade of Speakers ..etc
please read the whole thread.

first of all: do not connect the speakers without modification to your amp, you will most likely blow the amp.

Long story short:
The Bose rear speakers a wired very weird:
You would expect that you have a pair of speakers for the left and a pair for the right - wrong.
The two tweeters are wired together and the two subs a wired together.
So de facto the left channel drives the tweeters and the right channel the woofers - as I said weird.

So the first thing you need to do is to open the BOSE speaker encasement and re-wire the speakers and put a woofer and a tweeter in-line so now you end up at least with 3 Ohms on each channel - but it will sound like crap as the impedance of the speakers does not match your amp.

I ended up replacing all speakers in the Bose box with aftermarket speakers and a crossover.

I am a bit in a hurry at the moment, if you are interested I can put a more detailed description together later (maybe on the weekend), let me know.
