Man, when I ordered this sub, I was thinking 🤔 how big can this sub really be. When I opened up the boxes, I was stunned at how massive this beast is... huge motor and heavy asf. Have it running on a 3k rms amp in a custom box tuned to 32 hz, 2.5 cubes, 320amp alternator, and an extra xs power D3400 battery. This sub slams let me tell you. Very very happy with this subwoofer and the all around experience from purchase to playing music on it. This sub is for those who want that extra punch in the chest. If you don't have the muscle to back up this beast then it ain't for you
