Afternoon everyone,I normally have the stereo on around 8 to 10, a while back I noticed it was not as loud but put it down to the treatment I’m on , I don’t use the car much and is in the garage, took it out today and took some bags out of the boot and noticed the sub was not working, put volume up but still nothing,is there a fuse just for the sub, looked in the book and can’t see anything,about a year ago I did update system to 3.4, can’t say if it was working back then, any ideas, many thanks
