where does the radio battery feed originate?
is it shared with anything else?
This is an 89 Iwreck with the Blose system (or used to )

 

My 88 GTA has a fuse 10 amp dedicated to the radio but I can't vouch for other years/models. Radio fuses are usually tied to gauge cluster lights in other cars. I've never blown my radio fuse so I can't say for sure. You might want to try getting in touch with trickster, one of the mods on the electronics board.

You're not missing much with the bose system.

 

yeah, that fuse is the ignition feed.
and as faras the bose I know it blose, i had to redo the system in my 92 max because of it, but as usual they make awesome speaker pods.
