Just tapping into my first few posts and wanted to knock out the new guy post. I have started to do some improvements to the vehicle. Currently just a sub, K&N intake and sound deadend/proofed all four doors. I am currently trying to tackle the front floor pan and firewall. Now that the doors are proofed the only noise I hear is through the firewall/ floor pan. Any ideas or links to other threads about this same subject would be great. So far I am in love with my cobalt.
Peace,
