[QUOTE="keep_hope_alive, post: 8678819, member: 576029"] Specs on the factory systems are nearly non-existent. You can usually find a brochure that talks about total system wattage (peak) but rarely anything useful. Possible you could find info on a Lexus forum for that generation if you search long enough. Pin diagrams may be found if you pay for access to service manual websites, a day subscription can be enough to download a ton of info. Unlikely the factory amp harness has an adapter that makes replacement plug-and-play, i've never seen that for those models. You could do some digging and fine a website that sells the same harness, then make your own adapters. Most amplifiers can accept signals that range in voltage from low to high. Each factory system is unique if it uses a low signal into the amp or a high signal. The primary questions are how many speakers are in the car and if the speakers have passive crossovers mounted to them or if the factory amplifier had electronic crossovers. This is best determined by some research on your end looking at the number of amplifier outputs and tracing wire colors to each speaker. [/QUOTE]
