Hello guys so i just recently purchased 05 TL 6 speed with 135k miles.

I've noticed that the sound from the radio is not that great. I'd say the sound quality is like when you use a cheap FM transmitter to play music from your phone. It is clear but no bass. I've put the bass and subwoofer at +6 but they did not work.

Any suggestion?

Thanks a lot

 

post a video then.
