For sale is a loaded Probox with 2 8" Probox 500 watt subs that is built for a f150 super crew or super cab with a few inches sticking out. I had these subs in my 06 f150 super cab and they looked and sounded great. I had them in the truck for about 3 months before i traded the truck in so they are almost like new. hands down the best truck box on the market and the man that builds the boxes has the subs specially built for his boxes. I had a JL Audio JX500/1 hooked up to these subs which are wired at 2 ohms and they hit as hard as the RF P2 10" subs i had in the truck before i bought this setup. i paid $800 brand new so for $550 for a great box and subs is a steal. And to show you how much i love these subs i am going to buy a loaded Probox for my mustang after im done with the engine mods (reason why amp is not for sale). So if you are interested or have any questions please call Chris at .
