Amplifier Tuning - Remember, watch this video - http://vimeo.com/72214312
Testing the Actual Installation Prior to Tuning
First things first, after physically completing the installation, make sure your amplifier is
powered up properly. It needs to turn off and on with the key. The power light should
turn off when you take the key out of the ignition. Test this out a couple of times to
make sure. If it does not, and you are having trouble figuring out why, give us a call or
drop us a line. Trust us, it won’t be anything major. Go back over the above
connections, and you’ll undoubtedly find a small, silly mistake.
Now, go to the front of the car, and turn on the stereo. Put in your favorite CD (not a
burned CD, but one that was professionally mastered and recorded), and tune in to
your favorite track. We recommend using a very dynamic type of music, with many
types of musical variations within the CD. Make sure that your bass settings on your
radio are set in the middle or slightly lower. This will decrease distortion and increase
the overall sound quality in the vehicle.
General Tuning Tips - Baseline Settings
Use very light pressure when adjusting the dials on the amplifier. Use a small, jeweler’s
type flat-head screwdriver to make your adjustments.
Make sure all bass and treble settings on your radio or EQ are flat, or in the middle.
1. Preliminarily set the gains, crossovers, and crossover frequencies as follows:
Gains: Both gains, ¼ of a turn clockwise, or roughly 9 o’clock.
Crossovers: Set the crossover to LOW.
Crossover Frequency: Start with ~80hz.
Boost approximately 1/4 turn clockwise
2. LOC gains - Set these approximately 1/4 turn, or roughly 10 o’clock
Gain Adjustments:
-Begin turning up the volume until you hear the music at a reasonable level and
increase the volume slightly up to the point that you begin to hear distortion coming
from your interior speakers. Now, back down the volume until the distortion disappears
and stop there. Head back to the trunk and slowly begin adjusting the gain(s) of the
amplifier until you are content with the amount of bass being produced by the
subwoofer without any audible distortion of the woofer. Make sure that this blends in
with the rest of the music, and you’re on your way to a rich, full sound.
