So I think the next thing I want to do is reduce the rattle of my trunk due to my subwoofer. I put some foam and heavy duty tape between my license plate and the trunk, which stopped the rattle there easy enough.
But I think most of the rattle in the trunk is from the top of the trunk. Seem to be a common issue? It is my understanding that adding sound deadening materials to the top of the trunk should reduce the rattle quite a bit, and potentially help increase the amount of bass I hear in the front?
But also, wondering which sort of sound deadening material is decently priced and would do a good job? Trying to figure out cost of materials and types of things I would need to install it. Only negative to sound deadening I can think of, is that it adds weight to the car? But should help improve bass a bit?
Thanks!
