It calls for 5.5-6.5 ft³ ported. It will swallow 2500w with no problem. Even with just my stock 90amp alternator pushing a Hifonics 1900w to this sub... Even when I had to cram it in a sealed box that's under 4ft³... Even playing a rap song instead of a bass track with the windows down... It still did 138db at the windshield! The box isn't even aimed at the back of the trunk! The 18HD is a monster

We're so happy to hear you're satisfied !! Enjoy!
