2006 Ford Mustang How to Keep Stock Shaker 500 Radio Amps Working with New Head Unit

If you are replacing the stock Shaker 500 radio in your 2006 Ford Mustang (possibly others that use the Shaker 500 system) with an aftermarket head unit and want to keep the stock amplifiers working that power the subs in the doors, watch this. I used a Metra 70-5521 Radio Wiring Harness that has two plugs, one for the radio and one for the amps. This works for the 2006, not sure about any other years as Ford can change where wires are in their stock harnesses. ** Disclaimer: I am not an expert in anything.
