Sub making noise

jharar · 06-12-2018, 06:41 AM

I've just noticed from past few days every time I start my car when the sub comes on it makes kind of humming sound..

When I switch the ignition off sub still makes humming sound for few seconds then it goes off.

What could it be..?

Any advice..

Which sound system do you have ? there are three basic systems
If you have one with and amp check for water on the amp that
is a common problem with these.
