Figure 4: PIR installed on steel furring channel prior to drywall being placed.

3)(Fig. 4) shows the PIR installed against a steel stud furring channel. Attach the PIR with screws directly through the furring and into 24” strips of blocking installed on the upper side of the channel so that the screws will go into both. Ensure that overhead work is carried out safely, and according to local building codes.

4)After the PIR installation is complete, run your signal wires. At this time, have an electrician install electrical circuits for your sub, if required.

5)Also at this time, we recommend that you install a safety line, typically a light gauge wire rope, from a secure point on the support structure above the subwoofer. Attach this to the strapping on either side of the sub and suspend it in case the installation is compromised. Follow the instructions for wire rope installation from your wire rope supplier, and check with your local building code for specifics.
