This article is a very useful article teaching us How to adjust a JL audio car amplifier. The simple way to listen to good sound and great music is to adjust the amplifier. Many people pay very less attention to this and end up complaining the audio system or paying unnecessarily to get the amplifiers adjusted to hear the right sound track. As JL audio is renowned brand is car audio, let’s take them as standard for instructions for completing this job. Amplifiers of other brands can also be adjusted by following a similar procedure.
For getting high performance of amplifiers it is not enough to stop with hookups. In fact they are just the preliminary step. Proper adjustment of the amplifier is very much essential if we want to listen to quality music. In just few steps this article guides you in becoming an expert to do this amplifier adjustment.

The procedure involves fixing the cross over, adjusting the frequency, then setting of GCL and finally fixing the bass boost for the amplifier. Let us look at them in detail.
The first step is to determine the permissible frequency ranges. These are called cross over frequency. They act just like filters filtering low and high frequency sound signals from reaching the car speakers. The low tones or bass are usually removed by high pass filter and trebles or higher tones are eliminated or removed by low pass filter. Next we have to decide whether we have to fix the cross over at high pass filter or low pass filter. This is determined by what the amplifier powers. It can be small speakers or even sub woofers. In the former case we go usually for cross over fixed at HPF. If amplifiers powers a woofer we may fix the cross over to low pass.
The frequency in both cases is kept around hundred hertz. Few amplifiers like that of JL work over a wide range and variable settings for fixing cross over. So we have the advantage of filtering the sound and making only those sounds matching our taste to enter as frequency can be tuned higher or lower according to taste.
After setting the frequency we should fix the GCL or gain control level. This is very simple and similar to tuning. After the car receiver is switched on we should set it at a volume which we normally hear. Now when the music is being played adjust the GCL clockwise so that at that position signal is not received and gets distorted. At this position when it is tuned back to the original position the signal is received properly. Thus GCL of amplifier is now set.
This last step is optional. It is for people who love additional bass in their music. So just like frequency the bass boost is also fixed.
Thus we have learnt How to adjust a JL audio car amplifier by ourselves to tune the amplifier to enjoy our taste of music.
