so i have a 91 mk3 with factory cd,cassette,radio play with factory amplifier
car had sat for 12 yrs(due to old man being scared of car)
radio comes on, antenna goes up with no problem
turn radio to a station and you need to turn the volume button to the max to hear anything
tried the cd player and cassette player with same out come
checked for power, ground etc going to amp
everything checked out fine
anybody know anything else to try?
