Love the product.
Installation I left to an expert (“Bestbuy Geek Squad”)- mainly because of my novel use and added complication factor.
I use my F150 supercrew for tailgating at football or my deer lease around campfire.
Have another manufacturer’s (1)tonneau plus (2)clever swing out cases both sides of bed (both “Undercover” product) – also with bed rug for sound / vibration moderation. I have the speakers mounted facing rearward at back of truck protected by the swing out cases.
The system is powered from inside cab from SSL control module. This allows control either manually or remotely with cool remote key pad. Thus set up I have full use of truck standard system be it AM/FM; CD; Ipod etc……Can run independent of truck internal speakers.
