Radio Noise?

Turned The Key On in My 69 Charger Yesterday And Through The Rear Speakers Came a Contant Screeching Noise. The Radio Was Off.

Its Never Done This Before. The Only Thing I Changed Was Tapping Into The Front Turn Signals To Get My Hood Lights On The Same Circuit

There Was Also a Red Wire Coming From The Aftermarket Antenna. The Jack From It To The Radio and One Red Wire I Noticed Wasnt Connected..

Not Sure Where It Goes
