Great sounding little sub!

I have this subwoofer in a 0.8cu ft sealed truck box. It hits harder than I expected, I was surprised! Goes deep, down to around 25hz, even out of the box with no break-in time. It's wired to 4ohms driven by an 1100w Boss amp. I know folks will say I'm overpowering it, but I don't run my amps at max power, ever. They run cooler and last longer.
