Hey Guys,
I just picked up a 2000 SLS with the bose stereo. Good Sound but needs some more bottom end. I just happen to have a JL Audio 12w3v2 in a small sealed enclosure, with a soundstream amp laying around, so I figured that would be the perfect addition to round out the system.
I have taken a look a the factory wiring diagram for the Bose system. The head unit outputs simply left and right audio outputs into the amp. The rest is handled by the amp, before I tear it all apart and get out the oscilloscope and try to figure it out myself I figured I'd see if anyone knew.
1) Does the Bose headunit send a line level or speaker level audio out to the amp. That is where I plan to grab the signal to feed into my amp. Probably using a line output converter to be able to tweak the signal. My amp has it's own internal active crossover to tune the signal.
2) Does the bose headunit control volume or does the amp do it via serial data? That is, does the voltage level p-p change on the line output, and the bose amp just responds that way, or is the preamp in the Bose amp, and volume is controlled by the head unit telling the amp to raise the volume via the data bus?
Has anyone added a sub to an 00 bose system and happen to know the answer to that question?
Take care and thanks in advance!
George
