Sound System Upgrade
Crutchfield Customer Review (What's this?)
I started a sound system upgrade to my Ford F350 Superduty. The first stage was to replace the speaker system. As a part of that process, I removed the interior door panels (front & rear) and installed Dynamat & Dynaliner to the doors (covering the entire doors behind the interior trim) before installing the speakers. This created a completely new environment. Not only does this remove any potential vibration created by the sound, but is also adds some great acoustics to the trucks interior. A diesel truck creates considerably more noise than a gas truck, and this solved a large portion of that problem, combined with reducing road noise. I was completely surprised at the vast improvement by just adding these products.
Pros: Fantastic sound, no vibration, reduced road noise.
Cons: The products are a little pricey.
