I installed the PX6 in my F150. It worked fine until 6 months later I smelled smoke coming from the unit and it ceased to function. I had to remove it and put the 4" OEM unit back in place. I wrote Phoenix numerous times to coordinate returning the unit for a replacement. They acknowledged the receipt of the request but have refused to respond. So I now have a $600 boat anchor. Phoenix Automotive does not stand by their warranty. I do not like giving bad reviews but I have given them multiple chances to stand by their product. This was order # PAF2495
