trunk sound dampening
I notice most of my road noise is coming from the trunk, and I have been looking in several directions.
Has anyone had good luck with any particular cargo mat for sound dampening?
I'm also tempted to put some Noico or Dynamat on the underside of the floor there, between it and the battery. Any reason I shouldn't, such as battery heat?
I asked a local place for a quote on sound dampening, and they want $300 for the trunk, $300 for each pair of doors, $800 for the floor, $800 for the ceiling, and $150 for the firewall. All of that seems a bit high, but especially the trunk, though a professional job would likely be much better than what I would do. Am I wrong to think their prices are a bit steep?
