Mouchacho, What year is your es? I have a 98 and I did the bypass but only for the front and rear speakers, I then using the integrated wiring harness have left the factory sub hooked up and my stereo sounds great. but in your case, are you trying to replace the amplifier and use the factory head unit? If so , I am not too sure that will work well for you.

Your amp is under the passenger seat. You will need to run wire from your HU for each channel to the amp and then bypass it there. There is a thread on here somewhere on how to do it and which wires do what. I also think you could leave the RCA connection to your HU connected and leave the sub wires connected to the amp allowing you to still use the sub.

Good luck, and if I find the post I'll post a link here.

Default Help w/ power & ground

Hi guys,
I have a 97 es300 which should be the same bypass as the 98.
Following "kphu" I cut the speaker wires coming from the amp harness & connected the rear & front speaker wires directly to my new head unit. I have 3 questions
1. How will the new head unit power up?
2. Where should I run the ground coming from the new head unit?
3. Where do I connect the sub speaker wires coming from the amp harness?

Help Please.
