Adjusting the Amplifier

1. Disconnect the negative battery post and secure it to something so

accidental re-connection does not occur during the installation process.

2. Run all wires needed for the amplifier to work correctly. Do not attach the

fuse in the fuse holder by the battery until all wires have been plugged into

the amplifier.

3. Turn the amplifiers gain and boost all the way down (counter clockwise).

4. As a good "starting point" set low pass filter to 80Hz (7 clicks), set the

subsonic to the tuning frequency of your enclosure

on pg.13 for exact tuning)

5. Make sure Bass EQ switch is set to OFF and the Strap Mode switch is set

to MAS.

6. If using the supplied Remote Gain Control (Bass knob) turn the dial all the

way up to the max. (full clockwise)

7. Attach the recommended fuse

the main battery.

8. Re-attach the negative battery post from step 1.

9. Turn the head unit on and start at a low volume. Check amplifier to make

sure all wires are correct and no protection lights are on.

10. Set the head unit's tone controls, balance, and fader to the center or flat

position. Be sure to turn off any loudness or other signal processors.

11. Use a very clear original recording not mp3 or burned cd. Turn the volume

of the head unit to its maximum undistorted volume. On most quality head

units this is around 7/8 of the maximum volume.

12. Slowly turn up the gain (clockwise) to match the voltage output of the head

unit or until the speakers reach the maximum undistorted output. Keep an

eye on the clipping LED!

13. Re-adjust the low pass filter and phase if needed.

, and set the phase to 0.
