Well, I got my audio done finally. I got a MTX 6500D amp pushing two MTX 8000 12 inchers. They hit solid and hard and sound great until I close the trunk and it sounds like the trunk is going to blow off. Anyway to tighten the trunk down?

I don`t know about tightening your lid down. But you can pick up some dynomat, which is a sound deadener/absorber...it will keep the top of your trunk from rattling.

How does that keep the trunk from rattling? I have never used it.

You want dynamat, not dynomat. Dynamat is a metal vibration dampening pad. You can get a dynamat trunk kit direct from Dynamat (http://www.dynamat.com/), or you can usually get it from a car stereo shop.
edit: you can`t get it direct from them, but you can find a distributor on their site.

You might want to check your license plate. It is a huge contribution to rattle or vibration. Dynamat has a kit for plates as well. I know Circuit City carries it and Jackie Cooper Electronics, Best Buy, most of the big name electronics stores.

I forgot to mention that the plate is not on the car.

I had 12-12" JLW6`s in my "winter beater" car, powered by 6 Soundstream Reference 500`s... aside from the leaking back window that suddenly developed, I had several layers of Dynamat on all of the interior metal surfaces of the car - it still vibrated (go figure), but the dynamat helped a ton.
Dynamat absorbs sound waves/vibrations. Take the lid from a pan and hit it with a spoon - the lid will ring like a gong. Place your hand on the backside of it and hit it again - it won`t ring, but it will "thud". That`s sort of what dynamat does.

I have 2 12" speakers in my car, but the only thing that rattles is the liscense plate. Does the Dynamat liscense plate thing work, or are there any other solutions?

Yes, the dynamat works for license plates. Have you tried just using some rubber grommets behind the plate? That would be a nice $1.50 fix, if it works out.

2001civicex,
It`s actually quite a simple process. In addition to the sound deadening materials, you might want to check out the link below.... It`s from a forum that I consider the "Autopia of Civic Mods" :D
7thGenCivic.com DIY Page (http://www.7thgencivic.com/modules.php?s=&name=DIY&pa=list_pages_categories&cid=2)
Just scroll down to the "No More Trunk Rattle!" link.
(I never knew clearing my headlights could be so easy)

Yeah, talk about pop-up hell....LoL Not crazy about the speed either. Other than that, it`s a great site... I love how they`ve got a DIY section and it`s interesting how they always list the most recent searches whenever you try to do one yourself.
EDIT::: hope it works out for you. Fortunately, the trunk rattle article is one of the easiest to do. :)

yeah, the pop ups suck at work especially when it is for a penis enlargemnt or something. haha
Yeah, I also hope it works! I am going to try that tonight. I am sure it will though cause i can fell the trunk has some play and when i push on the trunk the ratlle goes away. Now I just have to hope that when I thow my license plate back on it won`t ratlle either. I got foam padding behind it though. Thanks again!

I had the same problem and to Dynomatt the entire trunk was going to be really expesive. So I went to Home Depot and in the roofing ailse they have a product called Peal-n-seal. It is like $15 a roll. I think I used 2 and may 1/4 of another one. But I pulled out all that was in the trunk and the carpet stuck it to the bare metal and violo no more rattling. Instead now my rear deck rattles :mad: :mad:
anyways I am going to peal and seal that as well. I also did the back of my license plate.
