A friend of mine just put a Boston Competitor 10" in his truck. He's running a JL 500/1 to it. The Boston in a 12" x 12"x 12" box. Its rated at 800 rms. The amp 500give or take. When he turns the volume up with the windows down. The sub sounds like its bottoming out. When the window are up it hits way harder and no signs of bottoming out. What can the problem be and how can we fix it? WHen its ran off a punch 100 its fine.

 
I dont really know how he did the gains. Can the gains not being set right affect the way a sub plays with the windows up or down? I told him to turn off the bass boost but he doesnt listen. But 500 watts going to a 800 rms sub? what do you think he should have the gains set to. Its a ford expo', jl 500/1, boston competitor 10, sealed box.
