Any Car Audio Gurus here? Soundproofing Q's

Hey thar, the one thing I want out of my car other the ability to take my **** to tahoe quickly and safely is to have some decent audio. If im going to spend time sitting in traffic in a cage, it better come with some good as music if you get what i mean.

I just bought a ton of JL stuff - but i gave it some thought and i decided that before i install everything, i should remember that my suburu is terribly loud when it comes to road noise.

It seems to me that if i don't address this issue first, there is no chance in getting any sort of real fidelity from my car audio.

Apparently, a buddy of mine can hook it up with installing hushmat. I looked it up and it seems like hushmat is pretty decent so i'll leaning towards going for it. what is the most effective way to reduce road noise that comes with stis?

What shoudl i be looking for and where should i get matted first ?

what is the best logical but reasonable way to increase soundproofing in a car? start with the doors and the wheel wells first?

Finally, what is a reasonable price range that i should be looking at when i have this done to my car? I dont want to get quoted and get ripped off.

Also, any recommendations on who does this kind of work is appreciated.

Doors and rear trunk are usually the spots to be sound deadened. You can also get some kind of 1/4" closed foam (look up "Ensolite" as an example) if you want extra sound deadening. If you wanna go hardcore and take out your seats and carpet and lay down some layers of sound deadening on the floors, that would also help a lot. Some people even go as far as putting some on the roof of the car. For the most part, just the doors and the trunk (so your car doesn't sound ghetto with the vibrations) makes a huge difference.

Ive been researching this also lately (just for road noise, not for audio). Raamat, DynoMat Xtreme and Ensolite like posted above get good reviews.

The only downside to this is that its expensive (if you pay a shop) and can take a long time to DIY. It also adds weight but this wouldnt be an issue unless you're competing or ultra sensitive.

If you search nasioc for "dynamat" or "sound deading" you'll find some good posts and pics. Some dudes take out seats, panels and mat down everything from the firewall, the floor, trunk, doors, roof - Must be like a BMW inside!

yea I'm wonderingwhat is themost effective way to approach sound deadening.

Altho i rather not soend a fortune, There is no way I have the time to do this myself. I don't mind getting it done in stages. I just want it done right.

If you want to deaden 99.5% of the sound in your Suby you're looking at about $2k worth of DynoMat Xtreme..

1. doors first.
2. trunk second. dont forget the trunk lid itself. then the shelf back there.


then if you have $$$ left over, do the entire passenger cabin.

remember if you wanna save a few $$$$, take a look a roofing material. the smell might last a while, but it was wayyyyy cheaper than dynamat, etc.

Word. I don't have any on my subaru though I probably will at some point. But on my caddy I've already done the roof. I'm half way done with the floor and I'm doing the doors. On the outside and inside of the door. I'm using the crazy peel n' seal stuff because it's all gonna be covered and it's a 50 year old 4400 pound car. But the stuff works good.
