Door panel vibration

[qdog]

Hi all, just after some ideas for a possible fix,

Have some aftermarket components installed on the front doors, sound response is real good - however when the volume is low - mid, have this annoying rattle from the door panels (i think) when low freq. gets played.

Mainly from the left door panel, not sure if I dropped something down the glovebox and its rattling away.

Is it a common problem? - Is that a part under the dash or panel that needs clamping down when installing better speakers?

and if its the door panel should i just be stuffing material in there to take up the void?

B4 "02 btw

Side question - how good/useful is sound proofing?

Make sure it\'s not the cone hitting something.

It could be part of your locking/latch mechanism, I haven\'t looked in a Subaru door for ages but I\'m pretty sure they use those rattly metal pushrod things.

Get some thin adhesive foam tape and put it behind them to stop it rattling.

And by sound proofing, I assume you mean sound deadening, such as Dynamat? It\'s good stuff, particularly for your front speakers, a small amount makes a big difference but you get into diminishing gains the more you add.

Dynamat is your friend. Custom kit can be found quite cheaply if you don\'t need too much, but double door kit best option if budget allows. Definitely worth it.

I put a 10" or so square of deadener directly behind the mid on the door skin, and mold the dynamat up around the speaker ring base (if using MDf) lastly cover any large voids with rest. Made a huge difference to mine.

Mine has the same thing lol. Going to check it out in the near future. Only had the car a couple of weeks.

Just had a thought, check how tight the glovebox closes, if that\'s loose it could be vibrating. mine did that when I first got it.
