Dimensions
Sub cut out: 11.125”, sub mounting depth: 6.25”
Installation Note: Installs behind the seats. Tools on the hump must be removed to install. What's nice is that you will not have to take out your jack or cut off the bolt that holds your tool kit in place. The main limitation is depth. This truck seems to have less space behind the seats than the previous model, so speaker depth is somewhat limited. Check out the speaker depth guide before buying your subs. You will likely have to sacrifice the last 2-3 clicks on your seat travel to give the box and subs enough space. In most cases, this will still leave you with plenty of legroom to drive comfortably while enjoying your new boom.
