On and off static/vibration

[Robin78]

Hi there. Hoping someone can point me in the right direction before I have to take it to the shop.
Bought a used Volvo xc60 (2013) radio sounded amazing for the base model. Suddenly it would sound staticky at times, maybe vibrating a little, but sounded less “noisy” at higher levels. It would be that way for a short trip and then it would be normal again.
seems like now it’s all the time. I’m not sure if this is a speaker issue? It comes from all for speakers, but not the tweeters. I’d hate to buy four new speakers and this not be the issue. Is it common for all four to go at the same time?? Any insight is welcome!!!
Thanks

I would remove the door panels or speaker coverings. 7+ years can do damage to factory speakers. Inspect them as it is free to do. Tweeters may have some form of crossover and or protection on the from the manufacture which may be why the noise doesn't come from them.

Thanks!! I just purchased trim panel removal tool. Good to know I’m on the right track. Just find it so odd that it’s all four speakers!

Older Silverado and Avalanche models had a similar issue. Moisture would get inside the doors and rust the speakers from the back. They would all bust within a short period of each other.

When I bought this 2008 G6 GT with the Monsoon system in it, all of the speakers were blown. All paper speakers.

A lot of vehicle manufacturers use foam surround basic speakers and they can deteriorate easily in 7 years making them sound like crap
