After market head unit
MAD sells this Pioneer CD/AM/FM receiver for about twice the street price but offers a "Bose compatable" version; I assume they supply the interface.
It realy amounts to either getting a receiver with pre-amp outputs or an interface to convert the speaker outputs to pre-amp levels.
Try our audio section.
Hi-Volt RCA Preouts (x3 pair) (Front/Rear + Subwoofer or Non-Fading) (Non-clipping 4.8V max)

As for keeping the bose speakers and amps, why? They were paper foam junk the day they were made. GM charged dealers $5 for replacement speakers when they blew. They also have a very fragile and tempermental amp located at each speaker that you will continually be replacing or fixing. Instead, get a speaker designed within the past decade that will last and sound good. Something like a Boston Acoustic RX 57 for front and RX97 for rear should work. You can go up or down from there price/quality etc. Those are $120 and $160 a pair respectively at http://www.tms-electronics.com and they work well with and without an external amp. If you "need" to keep the crappy bose speakers, you can get an adapter for around $80 from most car stereo shops to allow the system to work with your deck. It will convert the decks power to 1/2ohm low level input and then use the power from the bose amps to power the speakers. It often accompanies this with some really pleasant engine whine. I'd rip the whole thing out and get a system from a real company, not Blose. We used to make fun of them in the 80s when I was an installer mocking all the ignorant vette owners who boasted of their systems "capabilities". I didn't have the heart to tell them that if they installed a good aftermarket setup they could have had better sound for $1000 less, and that was 15 years ago. :yesnod:
