on the club lexus forum i posted on the guy said i should try by passing the factory amp and run the wires directly from the alpine headunit to the factory harness that comes from the car, i think that might be a real possible solution, i was also the car has a premium sound system, does that affect anything at all? i think im going to try to by pass the amp, i just kinda nervous about !Removed! things up with the factory harness cause if i do then im screwed
he gave me a wiring guide, for the factory harness, check it out added it as an attachment
and about what you first said yes.
"Okay, now I'm confused, too. I did a complete rework of our '95 ES300 stereo, and I've done several installs with Apline systems, and I'm not sure what you are referring to when you talk about the harnesses. There is a 'wiring harness' that comes with your new headunit, then there is/are the factory wiring harnesses, and then there is an interfacing adapter harness that I'm guessing is what you went out and bought so you can connect to the factory speakers/amp without having to cut wires, right?"
i have the harness that came with the alpine headunit. then the factory harness that connects the amp and the speakers. and then i went out and got another harness adapter like thing that has the 4 rca's coming out of it, so i would not have to cut any wires, its the rca's that are messing things up
