its not alt whine, i guess you could say its crackly.

when the right side of the unit has signal the right front speaker is loud as hell, staticy, garbled, and in general sounds distorted and ****ty. if only the left side is in then the left front speaker sounds fine, but its only that speaker, nothing else is getting signal.

the previous owner had this same unit installed in this same car before i purchased it, but removed it prior to sale and just gave it to me loose. so the unit shouldnt be faulty per say
