ok when my sisters radio was first installed the volume was like really loud at 15, then one day it got messed up and you have to have it at 20 to be really loud, then it was just messed up again and had to be put at 30 to be really loud. so i took the unit out and found 2 broken wires... a blue one and an orange one(dimmer) so i reconnected them. and now her red lights on the gauge cluster work and here radio is a bit louder.
but does anyone know how i can get it to be where it first was when it was loud at 15. i didn't see anymore messed up wires. nor any nobs on the back of the unit.
thanks,
Josh
