What is the best way to soundproof a classic vw beetle?

I have a 1971 vw beetle. It has been restored by the last owner and there seems to be little soundproofing in the engine bay and there is not much on the inside. Can anyone recommend sites/give advice?|||Hit up your local body shop supply joint for "Q-Pads". They're expensive, but they work great. Another cheaper suggestion is rubberized undercoating.


In my last Bug, I hosed down the firewall with undercoat, put on a layer of pads, then covered them with aluminum heat matting for a nice finished look. I also put pads on the inside, under the rug lining the storage bay behind the rear seat. Get under the seat as well. Undercoat inside the doors and rear side panels behind the interior panels. Hose down under the car too. Not just the floorboards, but under the trunk, fuel tank %26amp; all 4 fenders. Upgrade the carpets with some sort of thin pad (woven or foam) beneath. A new muffler couldn't hurt. Make sure your tailpipes are correctly adjusted (No, I'm not kidding. Adjusting them to the correct length reduces noise %26amp; sets the correct amount of back pressure).


Spray glue foam pad to the roof panel between it %26amp; the headliner. Shoot spray foam (Great Stuff) into the hollow rocker panels %26amp; roof ribs. If you do all this, you'll add probably 30 pounds to the car, but it'll be a lot quieter.


Remember: these cars (for all the amazing engineering that went into them) are basically just tin cans. They were designed %26amp; built to be inexpensive, not quiet %26amp; luxurious. Lots of hollow spaces. The slightest chirp or rattle gets amplified inside them.|||just stick some nice speakers in and turn the ******* up.

|||Dynamat is good, and expensive. I had a 73 Pinto, noisy as could be. I went to walmart in the autobody repair section and bought a bunch of cans of under seal. They are aerosol and cost about $6 each. Made a lot of difference.|||Either MidAmerica Motorworks or JC Whitney ...
