I didn't take advantage of it but I think this thread did indeed deliver to many... in their post count and thats about it.
I just can't wrap my mind around the concept of Jackhammer and SQ nevermind the whole earthquake and SQ. The sub is friggin named JACKHAMMER for crying out loud, do you think some SQ will possible come from it. In that power range I would be willing to put my money on the crown amps being the cleanest and best sounding for that many watts, certainly don't think they will be affecting your "SQ" with the jackhammer doing its thing. Good luck on taming that beast though.
Sometimes just rarely does it happen but there is such a thing as Too Big. The watts on the amp don't matter with a sub that big you need a BIG AMP (footprint wise) 200lb amp should suite a 369lb sub and it should all go in a massive lifted 6 door F-650 truck to complete the package.
