I have a 1992 ES 300 and want to know a couple of things. I need to know what the power behind the factory amp. Also how do I wire power through a deck. If I'm not running any power through the factory amp so I remove it or just let it sit there. Thanks!

 

I have a 2000 ES300 and when i purchased the head unit the guy told me I should be good as fas my interior speakers and he wasnt lying i havent had no issues and it crystal clear but i aslo have the Platinum edition not sure if that matters.

 

If you intend to bypass the factory amps you'll have to pull new wiring from the speakers to the deck. You will also have to install an amp for the subwoofer.
