1990 C4 Bose Rear Radio Speaker Harness - OEM Number(s) (12340000)
If you’ve got a 1990 Corvette with the Bose system and you’re tired of the rear amp feeling like it’s stuck in the past, this rear wiring harness is your easy button. It lets you drop in the newer 1991-1996 Bose rear 50 watt amplifier without hacking up your factory wiring, so you get a legit power bump and cleaner sound while keeping everything looking and behaving like GM meant it to. One end plugs into the four-pin lead coming from the radio, the other snaps into the six-pin on the amp, and those two extra speaker leads are already there waiting to do their job. In short, this harness is the bridge that makes your 1990 play nice with the newer amp, saving you time, headaches, and the kind of wiring “creativity” that usually ends in silence and regret.
