Before you begin:
1) Locate an area in the rear of the vehicle where you would
like to install your tube subwoofer.
2) Orient the subwoofer so that the active driver- front of
the tube- fires into a corner, about 2 to 4 inches away.
3) Inspect the mounting area to ensure that the mounting
screws will not damage the gas tank, electrical wiring, fuel
lines, spare tire, or any other parts of the vehicle.
4) Ensure that the chosen surface is solid enough to
withstand the stress of subwoofer mounting.
In a hatchback: the tube should lay parallel to the rear of
the vehicle, firing into the corners.
In a sedan: the tube should be secured against the sides of
the trunk, firing toward the rear of the vehicle.
In a trunk: the tube should be mounted behind seat, firing
outward.
RULE OF THUMB: Position the tube so the active
driver is facing a hard reflective surface (3-5”away).
This adds a 3dB gain to the total system response.
Mounting instructions:
1) Place the tube subwoofer in the desired mounting
location and mark the correct place on your vehicle to drill
the required mounting holes.
2) Mount the tube subwoofer by screwing or bolting to the
vehicle through both holes in each leg. Be sure that your
tube subwoofer is securely fastened to your vehicle!
Note: Due to the shifting and jarring that will occur in a
vehicle, the mounting legs should be checked periodically
to ensure that they are fastened securely in place.
Wiring instructions:
Locate the terminal cup on the rear of the tube subwoofer.
Insert the positive speaker output lead from your amplifier
into the gold plated red terminal on your subwoofer tube.
Repeat the process with the negative amplifierlead and
black terminal
Wiring multiple tubes:
Care should be taken to wire all speakers in proper
relativephase. However, if your bass response does not
increaseafter wiring an additional tube, you must reverse
its' polarity.To accomplish this, turn off your system, then
reverse the leads on the second tube subwoofer. If the
bass response improves, your phasing is correct.
In a hatchback: the tube should lay parallel to the
rear of the vehicle, firing into the corners.
In a sedan: the tube should be secured against the
sides of the trunk, firing toward the rear of the
vehicle.
