Well, you know what im packin in my trunk, so ill get straight to the point. I'm runnin' both of those on a 500 watt p5002 Rockford Amp, I'm not bridging them. When I turn my gain up, and the volume up, my subs make a almost hollow sound like wood vibrating. I have them mounted on to a sealed box, but tried to port them. The holes i made are about a inch and a half in diameter, and I stuffed them full with insulation so no air tries to get out. Even before when I hadn't made the holes it made the sound (Why I tried to port it myself in the first place). Would this be because my subs are blown, or a box problem? I know someone else posted this, but he had a ported box, I don't.
The insulation in the port is most likely your problem. A fully stuffed port will act about twice as long because the air travels through about half as fast and your enclosure will seem 1.35x the size (transmission line basics). It's gonna give you an odd (very low) tuning frequency that is probably to low for your subwoofer to handle, causing overexcursion. Seal the port holes with something solid, like MDF, and see how it sounds.
are hose just holes in the box or did you actually place ports in them? also are your subs wired out o phase? try switching the polarity on one of the subs and see how that sounds. ( swith the + and - on just ONE of the subs)
"Even before when I hadn't made the holes it made the sound" indicates this is not a port hole problem just wanted to point that out

It was a sealed box, i drilled holes in it myself. i put ducttape all in the inside of the hole making it so no air got out, it sounds a little better, but i will try the reverse polarity.
lol dude make a new box sounds like this one is getting pretty ghetto when u start usin words like duct tape
