Review on 🔊 Enhance Sound Quality: Metra 72-4568 Speaker Harness for GM Vehicles by Kenny Marozas

Seriously, replacing the factory speakers in a GM car saves you a headache! Check the equipment for your specific vehicle. I used them when replacing the factory speakers on my 2007 Silverado 1500 Classic double cab. These speaker wire harness adapters are well made. One end of the wire harness has a GM speaker connector and the other end has 2 spade terminals that connect directly to the replacement speaker. I was a bit concerned that blade terminals would be lost or sloppy. It's not like that at all. They were SUPER tight and attached well to the speaker terminals. Spend $5 per pair and avoid extra work and inconvenience. I did this to keep the cable and/or wiring harness from getting in the way of the power windows.
