Long story short, I bought a Honda Civic awhile back and the level of interior noise has been bugging me for some time now. It is to the point where I have to turn up the volume on my stereo to louder than I'd like while driving down the highway just to listen to talk radio.
I'm a student so I don't have a ton of cash to spare. I've heard good things about Dynamat, but I really don't have the resources for that. I also came across this
, but I don't know about the quality.
Oh, as a side question, there's also a small hole in the firewall that has been letting in cold air. I'm not entirely sure how I should go about patching that up. I would imagine that getting that repaired might also reduce some of the noise.
So, auto-savvy MeFites, what's the best *cheap* way to insulate my vehicle's interior from outside noise?
