In a sedan: the tube should be secured against the sides of
the trunk, firing toward the rear of the vehicle.

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.

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.
