New to this forum, this is my first post. I searched but didnt find much about this. Just got a '10 coupe EXL V6 with premium audio, only issue is on songs that have constant bass, it almost sounds like the front door speakers get silenced and all power goes to rear speakers. Any idea how to fix it/why this happens? When all speakers are working they sound fine, so I'm not looking to do a bunch of work on the car.
