I am new to cars and car audio, but I have this problem
For some reason I can't access subwoofer control through my player anymore. It just disappeared, it is possible that during this time car's battery has been removed
Now the cabling has been done again and audio has been moved to another car. All settings in amplifier and player have been through and all should be ok. Player works perfectly other than that I can't adjust the subwoofer level.
I heard a theory that some single file could have gone missing from my player software, is this possible?
My player is Kenwood, subwoofer and amplifier is Ground Zero. Do you need models/more technical info?
Please help me and thanks in advance !
