bro, if you have loud bass that's just how the shlt is going to go down. try not to be so anal about it. OR you can settle for lessor bass and go for SQ.

dont tighten bolts too much you can crack body panels, lights and strip stuff... Add deadener back there.... find out where exactly its comming from by pushing stuff n listening to the rattle...

its coming from behind the licenses plate. you get what im trying to say ? basically the trunk.

i dont stay up to date on what imports look like... if you have lights or parts of lights like some of those honda's do then take them out and dampen behind them... also dampen the trunk lid etc... maybe take pics n use arrows inside and out

U fix each rattle one at a time, find where its commin from and do everything u can to stop it from rattling, then move to the next spot. I had to get in some bad places to get most of my rattles, still have some that i have to fix tho.

Might be one of those cars that you just cant get all the rattles out. I have mine dampened pretty good, 3 layers dynomat extreme through rear deck, whole trunk from bottom to top, around lights and 2 layers behind license plate and my roof. Shit still rattles from my trunk, lol! Matter of fact it has moved my trunk lid so bad it is actually scratching paint off my back bumper from the trunk flexing. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

Vibration dampers like Damplifier will reduce the energy available to create rattles, but they won't always kill them all. As phyphoestilic said, you have to identify what is rattling and treat the source. A lot of good ideas have been put forth.

You get rattles when two hard surfaces vibrate against each other. That mean sone or both are loose and able to move. Doesn't mean anything is wrong, some things need to be able to move in order to work.

It sounds like it may be part of the latching mechanism that is rattling. No matter where it is coming from, foam tape and silicone caulk are your friends. Use little pieces of sound deadener to hold wires in place. Foam like the Rattle Pad you mentioned, or plain old Ensolite, Neprene or whatever closed cell foam you used over your vibration damper are great for making gaskets to keep trim panels from vibrating.

As mentioned, spoilers, tail lights, license plates, rear decks and trunk lift springs are classic sources.

closed cells or open cells ? which one ?

Yes.

The sound may be coming from that little air vent in the trunk. The vent has a flap of thin rubber or some other material that you can remove. I had this problem, and had a really bad sounding "rattle", even at low volume levels and removing the flap from the air vent solved it.

You can also loosen the bolts on the metal loop where your trunk latch catches, and move it up or down to have your trunk close tighter. That may help some.

It can be damn near impossible to completely eliminate all rattles, even after heavy sound deadening. That guy that heard the rattle-free Lexus, well....it's a Lexus. They're already pretty well sound deadened. I've heard of other TSX owners who've said that they rattle pretty bad just from driving. Nice car though.

for me it was night and day difference. i put one layer of raammat and it got rid of almost all the rattles. i'm sure if i put a few extra layers, it would help even more.

closed cells or open cells ? which one ?

Always always go with closed cell foam. 'Closed cell' means each cell of air in the foam has its own complete cell wall, no openings between each cell. This means as sound waves try to pass thru the closed cell foam, it encounters these walls. Open cell foams have gaps/openings between each cell, allowing a relatively unobstructed path through the material.

Closed cell foams are vastly superior to open cell for sound deadening. In fact, open cell foams are almost worthless for this. Also, closed cell foams will not soak up moisture to rust your vehicle, again because each cell has a completely closed wall. Open cell foams are a sponge, literally.

Like alluded to above, you cannot simply slap down a layer of deadening mat over everything and expect all rattles to disappear. There are various techniques that should be considered when deadening each rattle individually. Sometimes, merely placing a soft material between two pieces of sheetmetal will stop the noise cause by them rubbing together far better (and cheaper) than would simply slapping mat all over it all and calling it a day. Use the right materials, the proper techniques and a little common sense, and you can acheive very good results.

Cheers.
