Nikitaaa Posted April 19, 2012 Report Share Posted April 19, 2012 My subwoofer is port back sub up, and when I drive, the box literally flexes up and down. Yes, I have top to bottom bracing, but this is the WHOLE box moving. I have an l-bracket in the back and front of the box but it still moves.. What should I do?

nascarguy301 Posted April 19, 2012 Report Share Posted April 19, 2012 I could be wrong, but i would put another baffle on it Quote Bose = Buy other sound equipment. i love the rattle it's the best part! i need louder cheap amp any ideas? Link to comment Share on other sites More sharing options...
Nikitaaa Posted April 19, 2012 Author Report Share Posted April 19, 2012 I could be wrong, but i would put another baffle on it I used plenty of bracing when I made the box, so I didn't include a double baffle. An I just painted it. It would be a huge pain to add another baffle.

Kranny Posted April 19, 2012 Report Share Posted April 19, 2012 I could be wrong, but i would put another baffle on it it's not a flex problem. the whole box is lifting off the floor Quote Link to comment Share on other sites More sharing options...
Robby Holmes Posted April 19, 2012 Report Share Posted April 19, 2012 use L brackets to screw the box as a whole, down.

Nikitaaa Posted April 19, 2012 Author Report Share Posted April 19, 2012 use L brackets to screw the box as a whole, down. I'm already using them. Maybe the floor of my hatch isn't steady enough? Because it has the plastic false floor that seperates the box from the spare tire well..
