Review on HSTECH 72 4568 Selected Vehicles Adapters by Jack Ford

The side that attaches to the vehicle wiring harness is OK. However, the side connections on the loudspeaker side are too narrow for the corresponding connections on the loudspeakers I installed, the Fosgate Punch models. I paid close attention to polarity and different terminal sizes, but these adapters are just too narrow. I had to trim the width of each terminal about half a millimeter with wire cutters. I suspect that Metra adapters will not have this problem. If I were to do it again I would pay them a few extra bucks to save time.
