Mounting Location: The enclosure mounts under the rear bench seat without taking up interior space.

Inside the enclosure there are 0.205" male quick-slides (will accept 0.205" female quick slides) for both the positive and negative terminals. The wire can also be attached using the nuts holding the quick-slides in place.
Note: Speaker wire is needed to connect the terminals to the subwoofers.
