Crutchfield Customer Review (What's this?)
This ported box really gives you the hard hitting bass you want from a sub woofer. It made a huge difference compared to my old, sealed box. It comes with thick wire in the box to connect your sub woofers. Definitely worth the money spent.
Pros: So simple to install subwoofers
Cons: Very large, didn't fit in my trunk so I had to leave it hooked up in the back seat.
