Stock Speakers Stop Working.

I just bought a 2010 mazda 3 and have been loving the drive for the past week. However I have noticed an issue with the speakers over the last couple days where the speakers just stop working and I sit in silence. The dash says everything should be working and the only way I've found that temporary solves the problem is turning the car off and on again. Has anyone else had this issue and if so how did you go about fixing it? Thank you for any advice you could give me!

Sounds like the car you bought had an aftermarket stereo which the person poorly switched back to stock before the sale.

Possibly, My dad worked at Pioneer electronics for a good time of his life so come spring we are looking to put a larger sub woofer in it. Thanks!
