I believe, but can't confirm so I wont take credit for it, that I was the first, or at least among the first to use the stock LS/GS BOSE head unit and aftermarket amps and/or speakers. I did it the same way WhiteLegend did his and bought an aftermarket headunit wiring harness for Honda/Acura cars, only added RCS connectors to that and pluged that into the connector leading into the BOSE amp at back. That made it completely reversable. From there, it went into my PPI Precision Power PC 4100 amp. Using it with my stock BOSE speakers, it sounded marginally better. Using it with my aftermarket speakers, it sounded much better. While I am not a true Car Audio Competition personal, I do like high end audio. I am more of a Home Audiophile with some pretty good home audio eqipement from Meridian Ditial Audio, so I think I understand what good audio supposed to sound like. My friend also owns a high end Home Audio/Theater shop, so I've heared state of the art sound systems first hand as well. Also, back in the late 80s and early 90s, I was heavy into car audio and many of my friends installed, or worked for audio and audio repair shops. Anyway, done right, using the stock headunit is more than enough to compete with about 90-95% of aftermarket headunits in a well done system. The only thing I completely hate about the stock BOSE headunit is its lack of a true fader and balance. No real problem in its centered position, but the fact that you can't do a true fade or balance is irritating.
