I finally ordered the kit. It cost me $75.99 total, with shippping. I will be installing it either on Tuesday or Thursday, depending on the weather. Hopefully no more trunk rattle for me! I will post pics once I finish the install.

 

Let us know how it turns out!

 

that kit should be able to reduce that trunk vibration that you get when you have like 2 10" woofers in the back ,, I remeber I used to get that vibration , when I get a chance next month I am installing some sound dampening that mazdaspeedwest recomended in my ride
