The cheapest option is a standalone installation of insulation.
For good materials vseravno have to pay.

I got b-quiet for much cheaper than dynamat on eBay, its by most measurements the exact same material. It takes about 100 sq ft. to do the whole car. You don't have to do solid portions under the rear seat (no vibrations there). Suppose you don't have Home Depot, but dirt cheap rubberized roof insulation material will do the same job.

For heat problems, look into the A/C low pressure return line insulation mod.

I also am planning to do what you did on your Yaris! Just wanna know if you only put the b-quiet on the outer skin of the door or did you put it on the inside skin and outer skin of the door here the speaker is??

I only put it on the outside skin, because I didn't have anything to create a wall to cover the open gaps on the inside. I should probably go fix that.

Just covering the outside makes the door have a "luxury clunk" when it closes.

I thick coat of rubberized undercoating in the wheel wells makes a BIG difference. Very cheap project too!

I just looked on ebay. I wish that b-quiet stuff wasn't so pricey, I don't even put $2.50/sqft flooring in my house, much less something that goes unseen in my car. heh

wheel wells: rubberized undercoating / truck bed rubber spray. Someone also sells a anti-corrosive dense paint that you'd need multiple layers of. As cali_yaris said, it absolutely helps; I've applied more and more to finish off my sound deadening project - it isn't good enough to be the only solution, but fixing the wheel wells make a big difference in tire and rolling noise.

home depot: peel & seal. Anything that looks like it is made of rubber/a tar base dense flexible "asphalt" on one side, with fixed aluminum backing. Should also be pre-glued so it is less mess. Make sure it actually isn't asphalt...

Thanx allot!! This helped me allot! So the rubberizing, I just spray it on and that alone will make a huge difference?

I will head to the home depot and get that stuff. will you be able to hear the difference between dynamat and something like this?

THanx for your help! I appreciate it!!

The rubber stuff: yes, spray it on the inside of the wheel wells, on the metal thin surfaces that cover the tires (I spray the plastic parts and suspension too, but I'm not doing it right). Be careful not to spray on the exterior paint, but hold the can far enough away to get a nice spread. Shake the can very hard for the specified time - otherwise you just get paint and glue and no rubber. Use rubber gloves or hold the can with a trash bag; it gets messy.

The difference between dynamat and b-quiet or peel and seal is not appreciable. The material is essentially the same, short of a few m.m. difference in thickness. As your stuff will be way cheaper, you can just do double layer in the middle sections of the surfaces you cover. It has nothing to do with the material really - dynamat for $600 isn't magic or superior - it is all about adding mass to prevent the sheet metal from vibrating, while getting a good glue that will permanently stick even in rain, sun, winter and extremes of either. Use a roller to press the stuff into edges and get a good stick. I think good results are more about patient and thoughtful install than thickness of the material. If you want it even more quiet, get foam, like a foam mattress, and stuff it into the door frames.
