Thanks Kent. I was hoping to re-use the bose amps, even if it meant using 
impedance matching tansformers to get the line inputs to the right level. 
I don't know if the amps are any good, but I wanted to at least give them 
a shot before replacing everything. My 5k has the 10 speaker system and I 
am running a 4-channel sony am into the stock speakers and that seems to 
work fine. I don't think that a head unit would appreciate 1 ohm loads for 
very long. I havn't gotten any info back on the wire colors yet so likely 
time to start tracing.
