    Love the box. Hate that it was single terminal for 4 subs and also not meant for a lot of power. Box is already rattling from 4 American bass 1022 at 2ohm with 6k amps. I’m going to brace the port area with 2 inch dowels and hope it holds up. Other than that this thing sounds great

    Cut outs are WAY too big!

    Posted by JN on Dec 04, 2021

    The cut out holes are way too big, the subwoofer slides all around trying to center it. Then WORST of all when you do finally guess the center the drill holes for the mounting screws are RIDICULOUSLY close to the edge!!! How close you ask 1/8 of an inch or less depending on how well you guessed the center placement. TOTALLY UNACCEPTABLE!
