1. Prerequisites and Preparation
Prerequisites for install:
•A working stereo head unit feeding a signal to an amplifier
•An appropriate amplifier for the subwoofer used
•Appropriate wiring run to the carpet opening under the passenger seat
Tools required for install:
•13mm Socket Wrench (bolt removal)
oBoth deep socket or ratchet-hole will work
•Torque Wrench (bolt reinstallation)
2. Quick Install Overview
This section provides a very brief overview of the steps. It is not recommended that you use
this section as your sole installation instructions. Each section provides detailed information
on each step and failure to execute the details could result in a damaged product.
1. Slide the passenger seat forward
2. Remove rear rail trim
3. Remove rear bolts
4. Slide the seat back
5. Remove front bolts
6. Position seat so bottom is accessible
7. Bend in metal clips
8. Fasten wires against the seat bottom with zip ties
9. Attach wires to subwoofer
10. Place box in, widest rail on passenger door side
11. Bring the seat back down
12. Reinstall bolts and rail covers
3. Removing Rail Trim
The first step is to remove the rail covers that cover the bolts to remove the seat.
First, slide the passenger seat all the way forward (Figure 1).

3.1. Left Trim
Next, remove the left rail bezel trim. To do this, slide you hand behind the trim, locate the
clip, and squeeze both sides together (Figure 2). Push the clip outward and pop out the edge.
Once you have the front of the bezel popped out, slide the bezel towards the rear of the car,
it some come off at this point.
Figure 2
3.2. Right Trim
Now, remove the remaining bezel on the right side. To do this, reach to the back of the
bezel and pry the trim at the rear away from the bezel by putting you hand around the edge
(Figure 3). Then, being careful not to break the bezel, pull it towards the rear of the car.

4. Removing the Bolts
4.1. Rear Bolts
To remove the rear bolts, grab the wrench mentioned at the beginning of the guide and begin
removing the bolts (Figure 4). These bolts are on very tight and require a great deal of work
to remove. If you’re not strong enough, you can try a longer wrench (breaker bar).
Figure 4
4.2. Front Bolts
Next you will want to remove the front bolts. Start by moving up to the front seat and
putting the seat all the way back. Then, simply remove the front bolts like the rear bolts.
These should also be on firm and will require some work to break free.

5. Adjusting the Wiring
5.1. Positioning the Seat
Start out by moving the seat so you can work with the bottom easily. This can be
accomplished two ways: (A) removing the seat from the car, (B) lifting the front of the seat
up and leaning it against the back seats. Option A must be done with caution because you
could easily scratch your car but, once out, is safe to move around and easy to work with.
Option A all requires the removal of all the wires that are attached to the bottom of the seat.
Option B is the easiest and, while it did not hurt anything during our installs you may be
concerned with the rails digging into your carpet. Option B does not require the removal of
any wires. However, one mid-wire clip holding a wire to a metal bracket must be unclipped.
This clip can be reinstalled later or left off.
5.2. Adjusting the Clips
Once you have the bottom of the seat in an accessible location, it is time to start bending the
metal clips (Figure 5). Push the metal clips on right side in (side nearest the driver’s seat).
Don’t push excessively. You simply want to bend the clips gently out of the way. The
further you can get them out of the way, the better the seat will fit without any interference.
However, at the same time, you do not want to break the clips. Use caution and common
sense.
Figure 5
Now bend the remaining clip located toward the rear of the seat (Figure 6). You will want to
bend this all the way to the bottom of the seat.

6. Installing the Subwoofer
Now that the seat is prepared for the subwoofer, it is time to put it in. First, connect the
wires from your amplifier to the appropriate terminal (our box uses the standard red is
positive, black is negative terminals). Now, lay the box in between the seat posts with the
widest rail groove closest to the passenger door and the speaker closest to the center console
(Figure 7). Once the box is laid in, push it firmly toward the front of the car, this will help
ensure clearance for the rear rail covers when reinstalling the seat.
Please note: the subwoofer box in this image is an old prototype, not the current
subwoofer. This box fires upward, the box you received fires downward and you
will not see th e subwoofer as in th e image below. However, the long and short
sides remain th e same.

At this point, it is advisable to test the subwoofer and its wired connections (provided you
have the rest of the system installed). Make sure you have your amplifier setup properly
before performing the test.
7. Reinstalling the Seat
Now that your subwoofer is in place, it is time to get the seat back on. Extra caution is
needed during this step for two reasons. The first is that dropping the seat or placing it on
top of the box incorrectly could damage the speaker. The second reason is that the seats
weight and pressure from mounting are what hold the subwoofer down (not that it could come
out) and prevent it from sliding around.
7.1. If Seat Was Removed
If you removed the seat from the car earlier (see section 5.1Positioning the Seat) put it back
in exercising extreme caution. As you’re putting it back in, rest the rear rails first, reattach
all the wires, bring the seat down some, reattach the wire clip, and then slowly bring the front
rails down into position.
7.2. If Seat Was Tilted Back
If the seat was simply tilted back earlier, slowly bring the seat down, reattaching the wire clip
about half way. Make sure to pull the seat forward as you bring it down if the mounting holes
do not clear the floor bump.
7.3. Reinstalling the Bolts
Before bolting the seat on, make sure the thick black cable ends up in the wire gutter while
reattaching the seat (Figure 8).
Figure 8
We recommend reinstalling the bolts in the opposite order they were removed. It is easier to
get everything situated properly if the front bolts are installed half-way then the rear bolts

are installed. This gives you some room to move the seat around a little when we move to
the back and are trying to line up the rear bolt holes.
With the front bolts installed partially, move to the back seat. At this point, you may notice
that the seat rail is resting on the box, this intended as this mounts the box. You may want
to lift the seat very slightly and give the box a good push forward at this point to make sure
it did not slide back while dropping the seat. Install the left bolt first and then the right bolt.
Once you are sure the seat is mounted properly, torque these bolts down to Subaru torque
specifications for your vehicle (shop manual says 39 ft-lbs).
7.4. Reinstall Rail Covers
Simply reinstall the rail covers and you are finished.
The left rail cover can be a bit tricky. Push it flush against the center console wall while
holding the part with the clip outward (closest to the box). Slide it forward and once you are
sure the clip is in place, snap the clip in. The right rail can be pushed almost straight in,
snapping the two prongs around the seat mount.
