Hey guys I have a 2015 IS350, and the problem is that my stereo turns on and everything but no sound out of the speakers. I had try couple of times powering the car off and turning it back on, but still no sound. Anyone know what is the problem is?

 

Sounds like the amp went out

 

Amp...guessing that you don't have Mark Levinson audio?

 

All sources, CD, radio, Bluetooth and Aux are dead? Does the screen show stations, CD time elapsed, Bluetooth artist information?
Try pressing the overhead "SOS" button (even if you do not have a subscription) Do you get the vehicles voice to play?

 

Yea, i think so too. No i don't have the Mark Levinson. Do I have to get the stock amp or any after market is good?

 

Stock amp will plug right in. Aftermarket amp you will need to connect to the vehicle harness somehow.
Check eBay, you'll probably find a stock amp cheap.
Just check the part number on the one you have in the trunk and get the same.

 

+1 to what Sasnuke said.
A couple months ago, my amp also stopped working (no audio and you can't change the volume level). Luckily for me, I took it out to dry it out, and it actually worked after a day. If you've been driving in the rain or elements, this could be your issue.

Otherwise, a stock replacement will be by far the easiest. I looked into aftermarket but it was looking like a huge pain to find something capable. Be very careful too, because a lot of amps or amp bypasses, actually require the stock amp to be working.
