I am trying to add an amp and another sub woofer to my existing system. But I would like to know if anyone knows or has the wiring diagram for the premium 97 es300 system. I need to know what wires are the speaker wires from the radio that feed the amp?
Also why do the wires feeding the sub from the amp have voltage going through them?
Are the front door speakers grounded to the car?
and are the rears also?

Help anyone?

***Check with your local dealer. Ask for the EWD (or Electrical Wiring Diagram) for your car. The better dealerships will let you copy the pages out of the manual that you need.

Also why do the wires feeding the sub from the amp have voltage going through them?
***Voltage and current. No voltage or current = no sound.

Are the front door speakers grounded to the car?
***Nope. They utilize a "floating ground" arrangement.

and are the rears also?
***Floating ground here also.

Help anyone?
***Nah.

***It happens.

I sent you a private message asking a few more questions than what I posted here.
What is a floating ground? please explain in detail..simplified

The wires feeding the sub have enough current to light my 12v test light. It needs that much ? just for sound......wouldn't that fry another sub if I hooked it to those lines??

Percy please read the PM I sent you and any help will be greatly appreciated!!!
