Audio Systems: Amp install on stock 2002 ES300, mark levinson, rca outputs


Question
QUESTION: Hi Ernesto. I just read the advice u gave someone on adding an RCA input on a 2002 ES300. I can't wait to try it out. Except I will bypass CD changer all together. Well my question is what wires can I use to do the same concept but to add RCA outputs, to run an external amp. I lost the clip for my speaker level input. My buddy ran a set up like this on his 2005 RL. But I can't find pin out diagrams for my model "which is a 2002 ES300 with Mark Levinson sound system and Navigation. "Cleggsan already helped with the remote turn on, but thought u might help out with this. I want to run them off the ML amp side which is in the trunk. Thanks in advance.

ANSWER: you can add this hi low module from the rear speakers or the factory woofer
this will also send the 12 remote to the amplifier comes with the blue wire

QUESTION: Although I appreciate your time and answer. I was more interested in knowing what the pre amp wires are on this system. According to a harness made by Metra " http://www.metraonline.com/part/70-8113 " there are such wires the front and rear. I have been thinking the past few days and came up with the crazy idea of installing an EQ between the stock navigation, and the stock Mark Levinson amp so that I can fine tune the sound. Also in the process, add the RCA output for my sub.
I have Never seen this before and know it is possible. All I need to know is what color those four wires are Front L/R and Rear L/R, and I am in business. I have Looked everywhere and can not find any diagrams. My last option is to splice each wire individually and change the fade to see what changes. But like I said last resort. Now that the idea is in my head I won't be ok untill I have it working.

Answer
we have try to get the signal from the radio before but it comes out in a balance share ground, out of the radio, the new radio will work ok because the factory amplifier is capable of individual grounds, it will work but the sound quality is not going to be good also the balance fader will have a problem  and the signal is not going to be enought for the preamp unless you a a line driver before

good luck
