I have 2006 Lexus Gs 300 awd
Main Fuse and Alternator replaced everything works now but no sound out of the Speakers, was told to check the Amp Fuse any one got Ideas?

 

Your amp would be in the back of the trunk, passenger side there's a little lid on the floor of the trunk (passenger side, once again). Lift it up and your amp is there.

Check to see if you're getting power with a multimeter. Also you can check fuses there.

There are three total fuse locations for our vehicle. one on the driver side under the hood, one on driver side underneath the footwell (front driver side) one on the passenger side underneath footwell (front passenger side), and one in the trunk (driver side up, but facing you rather than on the floor).

Hope this helps, GL!

 

I am having a mechanic look at it

 

NP, and GL! Let us know what happened when your mechanic figures it out!

 

Amp problem is a main culprit.

 

did you ever figure this out? my car is having the same issue... just recently got the alternator replaced as well.
