Well if your hearing too much rattling I think you should buy some dynamat you can get it on e-bay for a good price. But from what I've seen it is alot of work to lay down and to cut and piece everything up. They also have the spray i'm not sure if that works though.

First and foremost, read the sound deadening DIY. Mat deadener will do absouloutely nothing for you unless you do a few steps prior to that, such as foaming the trunk lid, foaming everywhere between gaps b/t pieces of metal pretty much. Simply matting will only trap the rattles in. There are a lot of other things that can be done which are covered in the deadening DIY stickied at the top.

Everyone's civic that I've sat in, rattles. Moreso on the outside, but the plastic trim piece in the back in the likely culprit. There are several threads on some cheap alternatives to fix it. I actually put in carpet pad between the metal and trim. Ghetto, but it worked.

By the way, try searching because although most are very helpful, some of these guys aren't too understanding why you can't be on the board 24/7 and read every thread.

"You talkin 'bout me?" I was mainly telling him that this issue has been covered many, many, many, many, many, many, many times before. Some searching, or simply reading the DIY at the top gives more answers than what will be given. Check your license plate too, and move the trunk latch as well, btw.

Reading the DIY will also give tons more info than we are giving here.

Our cars are notoriously bad for rattle issues. Don't ask why, maybe honda is working in conjunction with the manufacturers of deadeners because they know that civics are the most budget friendly tuner platform.

Because civics are economy cars. If they made them with the same standards of quality as accords, they would have to charge more. FYI: I drove a 04 Sentra SpecV previously, and they suffered much worse in the rattle/road noise/wind noise area.

The biggest problem is people putting giant subs in their trunks, crossing them around 60Hz, and wanting to feel base, without their cars feeling the bass.

I'll be dropping some Raammat in my car this weekend, in addition to the berberesqe currently under the carpet, and weather stripping on the trunk, but mostly because I want to drive the highway in peace.

Well we definetly know they are not working with ANY speaker manufacturers b/c of the PITA it is to change any speaker in our car.

The Pontiac bonneville and firebird are not economy cars, yet they rattle 10 times more than Civics. It's a factor that Civics are economy cars but its not an explaination. Sealing the friction zones when designing the car would have only made the price go up by about 50 bucks. It's just the design.
