Placement

The basic objectives:

1) Make the subwoofer sound like it’s in the front of the car

(even when the subwoofer is in the back of the car).

2) Raise the perceived soundstage to ear level and solidify the center image (even when your front speakers are closer to your feet).

Both objectives are accomplished by shifting the signal phase, primarily in the lower midrange frequencies, resulting in arrival time corrections to the sound from your front speakers. In a typical autosound system, the signal path is divided into different frequency ranges (subwoofer, midrange, etc.) as well as locations (front and rear). For best results, localizing your subwoofer to the front, you will need an active crossover sending only subwoofer frequencies to the amplifier running your subwoofers.

INSTALLATION / MOUNTING

NOTE:

Before beginning, disconnect the negative (-) terminal of the battery to prevent an electrical short to ground. Reconnect the negative terminal only after all connections have been made.

Mounting

To prevent damage to the Phase Shifter while driving, mount it in a secure place. Choosing the appropriate location will depend upon your vehicle and the complexity of your system design. Typical mounting locations would be in the same location as your amplifiers and or crossovers. Never mount the component in a location that would subject it to immersion or exposure to water.

Once a location has been chosen, securely mount the

using the four screws supplied. Be Careful! Inspect the area underneath to be sure you are not drilling into wires, brake or fuel lines, etc. that could be damaged by the drill bit or screws.
