Does anyone have the current part numbers for the front speaker harness adapters and the rear speaker harness adapters? I'm really getting in the weeds on this one. Thought this would be an easy search, but I've been out of the car audio game for a number of years and all I can find are broken links or discontinued part numbers when searching on here. I have an 89 Firebird and a 90 Firebird Formula (need front and rear adapters for both cars) I have a new set of speakers for both cars and don't want to cut the stock harnesses.

Thanks for the help!

Awesome! Thanks!

 

When you are installing those, be careful that the polarity is not reversed. Some of these are manufactured wrong.

 

The other way to go is to just rip the connector off junk speakers, and solder new wires to the contacts. Never had much issue finding junk speakers to pilfer. I'd imagine there's a delphi/aptiv part# for the connector and terminals too, but I haven't found it (yet).

 

An't that just great. Thanks for the tip!
