It's a brand new Kenwood. Been in the car less than a month. Always sounded Damn good. With recent weather I ditch my car in the snow... Glad to get it towed out. I didn't both listening to music that night. The next day I plug in my phone and it sounds terrible. The radio music is like ehh but my phone music sounds like shit... I'm hoping it's the ground? I don't think any of the door speakers would cause this I don't think they got wet but I could be mistaken

what kind of temperatures did this happen in?

It was like no less than 25 degrees out but I had the heat cranking.

how hard a hit was it when you went in the ditch?

might be wiring but if it was fairly hard you may have damaged something in the deck.

It's was a really soft landing. It was a snow covered road. And I just slid down and stopped near the ditch. I was thinking snow in my engin*** or something

I looked in my audio port. It's fucked
