necessary to protect your investment
Crutchfield Customer Review (What's this?)
Installation was a bit of a PITA on my 12TW-3 but I eventually got it on. Once it was on its very secure. Thin gauge metal should hold up to most normal bumps from loose items in the trunk. After spending $300 on a sub whats a little bit more money?
Pros: protects sub
Cons: was a little finicky to install
