Here are some pictures of my first sub box for my car. It was made for my DA6, but also fit my EF8, along with my EF9 quite well!

The above picture shows it inside my EF9.
The picture below shows how little room i have left in my boot as a result!

Heres a picture of the sub box out of my car showing the nicks i made in the side of it to allow it to sit in between the shock towers of my DA6, utilising the plastic triangle peices that come out to secure the box in this location.

The above picture is a my civic when it had 14's.The picture below shows it with 16 inch RP-01's, which ive just put on.

Future plans for my civic include a new sub install, the battery being relocated to the boot and a re-spray in a black colour.
The plan for the new sub install is to have an enclosure utilising the spare tyre well with the amps covered by perspex, at the same height as the subwoofer. If anyone has a simliar setup in their pages please leave me a link, cheers.
