sound proofing car? - 6G Celicas Forums

Topic #72085 39 posts Started by 96stgreendemon
so i just got some nice alpine type s speakers and i really want them to sound as good as they can, so i decided i may soundproof my car or at least try to reduce my rattle, does anyone know if that great stuff foam will work for this? and please dont smack me for this, just an idea

not really the intended purpose.

dynamat is what you want.
yeah but dyno mat is way out of my price range

Dynamat is your best bet but not the cheapest... My buddy stripped his 240 and his speakers were mounted to bare sheet metal. We ended up ashfaulting it. Added alittle insulation, messy to work with and smells bad for a bit but haha its poor mans dynamat tongue.gif
it works and it doesn't....i sound proof my whole car it is doesn't seem to work too well. i still get rattles and noises. you just need to find out where it is coming from....if it is the doors, you might need to adjust your door height to close better, adjust the windows and tighten the bolts and screws...heck, try getting some weatherstrips to replace the old one so when driving, the wind doesn't get in and cause more vibration

eDead you can buy in a can and paint/spray it on.

use this. frost king insulation

its like a sticker on one side, and foil on the other.

regular insulation isn;t the best idea.. you could get fiberglass spores or whatever all in your cabin...

and if you spill liquid it'll soak it right up and potentially get moldy

this just has a foil backing so no worry about either of those ^

oooh and way cheaper
I'm going the RaamMat option, myself. http://www.raamaudio.com. Here's some pix I took along the way; I haven't completed the project yet, this was just the floorboard phase. I'll post up a complete "how-to" when it's all finished. I've got the door panels and trunk left to do.

I don't normally drive fast, but when I do its on a curvy section of this island
sometimes its not just sound proofing, sometimes you just need to pad certain things or create padding between, not just wrapping the walls. such as rubber washers

Turn the bass down and save up for dynomat. Don't use spray foam

I don't think our cars will EVER be *too* quiet; it's just a matter of making them less noisy! Especially if you've got 17" wheels and no exhaust resonator kindasad.gif

Absolutely true! Sound dampening material is just part of the whole deal; it's best to start with that first to reduce the road noise, and then isolate the rattles and vibrations. What I have posted above is literally just the first stage of laying down the sound deadening on the floorboards and rear wheel wells (94 ST came with virtually NONE to begin with). After I laid down the stuff you see in the photos, I laid Ensolite down over top of it, which is an ultra-light density closed cell PVC foam mat material. NASA ftw tongue.gif I just didn't take pictures with the ensolite layed down, I'd planned to when I do the doors and hatch floor.
griffgirl whats the total weigh of all that stuff?
The package that arrived to me weighed 40lbs - that includes the material that will go on the doors on in the hatch floor. Packaging itself was maybe a pound if that, so call it 39#. My car is never gonna be a time attack machine laugh.gif so the extra weight is negligible to me. I can probably cut that in half by pulling out the spare tire in the rear - since I've got 17" wheels, it's not like I'll ever use the spare anyway tongue.gif
Most of my rattles were coming from the blown struts on my car. The rears were really bad. Now that those are replaced I'm hearing the front halfshafts and bearings. I plan on soundproofing after I stop hearing things that need to be fixed. Road noise on the highway can get pretty bad sometimes.

Why not?

And I'm not sure if this has to do with the low mileage or the fact that it's a facelift model (and therefore, has more sound deadening), but my car is perfectly fine. I hear barely any rattles, really only when I go over bumps, along with some creaking. But when I'm driving, I hear no rattles. I have the music on (and pretty loud at that) 99% of the time, so really, I have no issues to complain about. There is a fair bit of road noise, partially because my tires are unevenly worn. However, I like the road noise (of the Celica, not the added noise of the tires); it lets me know what's going on and helps to keep the car from feeling numb. All in all, I wouldn't change a thing. Honestly. When I drive my dad's Audi A4, I feel like the car is disconnected from the road, just because it's so quiet and there's less feedback from the wheel.

God, I love my car. 6GC forever. <3

I've planned on sound proofing my car since it's so freakin' noisy. It's like made of paper-thin metal, lol. It has no insulation whatsoever. You have the carpet and then bare metal. rolleyes.gif But I don't want to add additional weight. The 3S-GTE will make it heavier, and I'm trying to stay under 2,800 lb. with spare, all liquids and fuel topped off and sound system...and me on it. Just for mental peace purposes. tongue.gif

i got alot of dynomat from sonixelectroix.com for really cheap more then i needed.
Yes, carpet padding helps and is a cheap alternative to sound deadening material. In fact, I've got a crapload of it if anyone wants it, just pay the shipping and you can have it.

OMG a ghost! Nice to see ya, how are you?!
Has anyone done the license plate bezel (center piece) yet, that seems to be the biggest rattle for sounds.

I have! Haha I stuck a piece of pink insulation (like actual house insulation) behind the bezel and tightened it so the insulation wouldn't fall. Can't even be seen from the outside and no more rattles.

I coverd my doors in dynomat when I changed out my speakers. The differance in sound is unbeliveable, the bass is deeper and loader and no rattles. Eventually I will do pretty much the whole interior, I am going for the best sound not so much the fastest car.

I'll have to do that then. My door speakers (Infinity Kappa 60.7cs) sound awful in my Celica. They have no bass at all. I have installed them in other cars and they sound amazing.

Yeah, I highly recommend investing in some decent sound deadening. And for that matter, I cannot recommend raammat highly enough. Rick (the owner) is just an awesome guy, super friendly and REALLY knows his stuff, and his prices are VERY decent. In fact right now he's got a special (I think it's still up) on material you use for your floorboards, and if you buy the discounted floorboard material along with the other stuff you need to do your doors and trunk, wheel wells, etc, you can do your entire car for about $200. He's also very responsive to emails with questions, etc. http://www.raamaudio.com

I haven't done mine yet, I don't seem to notice my rattling, but that could be because I haven't finished the rest of my car yet, and once IT'S quiet, I'll actually hear the license plate bezel lol If I have enough material left over after the doors and hatch, I'll probably do the midsection of the license plate panel and maybe some double stick foam around the edges.

I love my kappas. Its all in the deck, amp, and tuning.
is there any sound insulation inside the dashboard where the firewall is?

Just a thought: I also put the little extra bits I had (yes, b/c I cut everything like the OCD freak I am) here behind the rear speakers. I had stock speakers all around and it sounded great inside.
