If you've hooked an amplifier up in your car, you may now be asking yourself: "How do I adjust my car amplifier?" It's a good question. If your amp isn't adjusted and set properly, the sound quality that results won't be nearly as good as it could be.
Instructions
1. Turn on your stereo and put in your test CD. The test CD should be a well-recorded disc of music of the type you like to listen to most often in your car.
2. Set your car stereo at a moderate listening level. Then, adjust the "Gain" control on your amp up (it will be a small knob with "Gain" printed by it) until the sound of the music you're listening to becomes slightly distorted. At this point, turn the "Gain" control down slightly until the music is undistorted.
3. Set the high-pass filter for your full-range speakers. If the amp is going to full-range speakers, like door speakers, turn on the high-pass filter for the channels powering those speakers. If the high-pass filter has a variable setting, put it at 100 Hz.
4. Set the low-pass filter for your subwoofer. If the amp is powering a subwoofer, turn on the low-pass filter for the channels powering those speakers. If the low-pass filter has a variable setting, put it at 100 Hz.
5. Adjust the bass boost. Many amps have a bass boost circuit. If you're powering a subwoofer, turn it on and listen to the music. If you're satisfied with the level of bass, leave it on. If it's too much for your taste, turn it off.
