looks like one of my stock wheels after I caught a curb this winter hidden in a not so well plowed parking lot

I have 14 speakers but not in the application that you're looking for as it's 8 8"s.

rds is what some channels use to communicate info for display on a RDS compatible HU some use it to display traffic info, news headlines, song name, etc It's up to the radio station what they send for display. Around here there's a certain station that'll display song title and artist (like a MP3 ID3 tag) then when he's talking he'll type in whatever....like the station phone number or random thoughts in his mind...or what he'd like to do to the lady talking to him on air (that's landed him in hot water before though).

You are correct.
