Hey all, I have a Alpine CDA-9830 that is a DADK (Dead as a Door ****), tested fuses and wiring and all is good, has anyone ever had this happen with this HU? Anyone have any experience in repairing HU's? Just curious if it be a cheap thing to fix or not... paid 30 bucks for the thing so was hoping it be easy fix but so far.... im not so sure lol...
