2012 Mazda 6
Crutchfield Customer Review (What's this?)
It's a metal grill for your sub. I mean, what do you expect? It's made from some pretty durable looking metal. It's protecting my dual subs from all the stuff in my trunk. It's worth it. You always by a case for your phone, right? Same thing. Don't ruin the subs you spent so much money on get messed up.
Pros: Good, strong metal.
Cons: A little pricey compared to how much the speakers cost individually.
