What Home Depot insulation have you used under your carpet?
Fat Mat is about the cheapest and it comes on a roll thats 2' wide, so it covers large areas quickly. I used the next step up in their line called Rattle Trap. Ive used it on two cars and it works awesome for noise and some thermal heat reduction. On my A/C car I also used HD thermal barrier over the top of the fat mat. Keeps the heat out and the cool in!
