ok, just installed my new 15qd2 with bp today. 4.8 cuft ported at 28 hz...rockford p1000-1bd. yes thing slams louder then i could have imagined. only one problem.

i think i will be able to get rid of most of the trunk rattle, but it's the sunroof then driving me nuts. i need to get an sd card reader to load some pics and vids from my phone...

every time i start playing some really low notes, the sunroof starts banging so bad that's about all i hear inside.

anyone have this issue or know how to fix it? any ideas would be great!

oh yes it's a 99' infiniti i30.

Turn the volume down is the main solution.

lol that's no fun....if i didnt have a sun roof, I would just take down my headliner, and deaden the roof, (figured out it'st he roof rattling on the sunroof, not the sunroof itself.) I just don't want to take down the headliner if i won't be able to get tot he trouble spot. it's a 99 and the headliner is probably quite brittle. well any other suggestions are much appreciated!!
