I am getting ready to update my sound system with some better products. Right now I am running two 12" MTX 4000's in a open box with a 600w Profile California series amp. The trunk rattles like hell, and I was wondering if I got a sealed box if that would help eliminate some of the rattle. And if so, what kind of sealed box would you recommend. Remember I want something good looking as well.

what exactly rattles? upgrading to 2 better subs, even if they are going in a sealed box, will still make **** rattle i'm assuming your rear deck, spoiler, liscense plate, and possibly the seat belt mechanisms rattle. all can be fixed without spending much money and if you are spending the money on two decent subs, why not spend the money on a good custom built box? the box is what controls 90% of the sound. i tell people that they should spend more on the box than the subs i can make a $40 sub sound like a $200 sub in a good box, but a ****ty box can make a $200 sub sound like a $40 sub it's all about the box.

if it's your rear deck, dynamat won't help that much with my old 15 setup the rear deck literally jumped and broke the fasteners that thing rattled like hell against the back window. the 3rd brake light is the worst. put some thin weather stripping around that, and the back edge of the rear deck, where it meets the glass. then listen to see if the bottom side needs a little padding $2 worth of weather stripping will take car of 90% of the rattles of a normal system

Yeah I know how you feel. I might see what I can remove from the rear deck and see if that helps matters at all. For the most part I got all the interior back in, except for that one mystery piece that I never figured out. You should see my nice collection of screws that never went back in either.

Alright Blue here is another question for you. Since I am going the complete show route which entails the need for a kick ass system, a thought popped into my head. I was thinking about adding another 12" sub along with the other 2 I am ordering. I want to mount it in the floor facing up, somewhere in the center. Now this would put it right above the hole for the spare tire, so, how would I go about mounting it? I am assuming I would need some sort of custom box correct?Last edited by McCorkle; 01-02-2004, 01:49 AM.

yep, that'll definitely need a custom box. if you are going with 3 for show, i'd go completely custom fiberglassed through the whole trunk. 2 subs mounted normally, one inverted there isn't a huge need for the 3rd sub, as it won't create as big of a difference as going from one to 2.
for something easy, make something like asylum24's setup, except with 3 subs facing the rear. then mount the amp(s) on the sides, behind the wheel well. and put a spare rim in the center of your trunk. to do that, you'll probably want to inver the outer 2 subs, and keep the middle one mounted regular with those 2 inverted, keep in mind that their air chambers need to be smaller than the one that is regular.
