I just had a RF punch 250a2 amp, and one Fosgate He2 12" sub installed. The box is firing to the back of the cab and it sounds good, but I see alot of people here firing their subs down. I dont know a whole lot about systems, does it have to do with air space? and im getting a little rattle from the doors, does that Dynamat stuff really work? Thanks in advance for any help-VIC

 

My 12 is firing forward.I think its just whatever the installer thinks is best.That dynamat stuff is great. I put some in another vehicle because my 2 eclipse 10s were gonna rattle that thing apart.In withthe dynamat out with the ratles.
