    Trunk Vibration (Subwoofer)

    Basically I ripped the guts out of my old car stereo an installed them in my '02 WRX. The dash is still all ripped apart because I can't find a store that sells the piece that holds the head unit in place. Basically it's just sitting in the cavity where the stock unit was. Anyway, I had a Jeep before so the Dual 12'' subs don't fit the best in my trunk but I make do. It sounds pretty good, too, but there's this god-awful vibration coming from the trunk that I just cannot get rid of. It seems to be worst when the trunk is closed, making me think it is the lid. I was going to buy some of that sound deadening stuff they sell at Best Buy and stuff it in the trunk lid, but I don't even know if that's the problem or if it will help.

    Oh, and it's not the license plate which also vibrates but is tolerable. Whatever this is is much louder and much more annoying. It's really ruining my listening experience. Suggestions?

    Does it sound like it's coming from either of the rear fenders? My sub causes the rubber flappy baffles (no idea what they're called) to vibrate behind the carpeting where the jack is. Pretty sure they're there to equalize the pressure in the trunk which might be why it's worse with the trunk closed. Just a possibility. It could totally be the trunk.

    I closed the trunk and cranked the bass. When I press on the back of the lid where "Subaru" is written, the vibration decreases a lot. I think I'll try the sound deadening stuff.

    i suggest putting some on the top and bottom of the trunk lid as well as inside it. Also put some on both side panels(tire well) behind the carpet. This should help out quite a bit.

    u need to buy a double din dash mounting kit for your head unit, just head to any stereo shop (even Best Buy, just go to their stereo installation area) and get one. It isn't that expensive.
    or get it from crutchfield
    Dash Pocket Fits select 1994-up Mitsubishi, Saab, Subaru, and Volkswagen models at Crutchfield.com

    As for the rattling, Dynamat your trunk and your license plate.

    the only thing with those face-plate is that it doesn't look good.
    I made one myself and it looks great. You just need a bit of imagination.

    I used a charcoal peace of metal and a grill for bumper cut it ,bend it and screw it.

    I had problems with that thing vibrating as well, my exhaust was causing it. It bugged the hell out of me.
