Review on 🔌 Improved SCOSCHE GM02B Car Speaker Wire Harness Kit for Select 1988-2005 GM Vehicles - Connect Aftermarket Stereo with Ease by Jeff Pettis

2001 Chevy Tahoe LS (with Onstar, no BOSE, with sensor subwoofer) Alpine CDE143BT. Turning on the remote amp (the blue/white wire from Alpine) had to be connected to the pink/pink wire on the other connector on the GM radio (my stock GM radio had 2 connectors). If you don't connect the pink wire to the secondary radio's blue/white wire, the main Alpine unit will turn on but there will be no sound because the series amp is off.
