JL amp 300/4 gain help
Hey all.
Quick question.....
On JL amps....there isn't a "gain" setting labeled.....
The only thing I could find was a dial labeled "Input Sensitivity."
Is this the same thing?
How do I set the "gain" or "imput sensitivity"?
The manual is lacking in this area.....

What you want to do is maximize the electrical voltage going to the amplifier in the rca cables to try and minimize the inherent noise of rca's in vehicles.
Basically, turn the gain or sensitivity WAY down on your amp and crank the volume on your head unit. Turn the volume up until just before the point of distortion (not max. amp output but max. head unit output).
Leave the volume on the head unit up just to before it distorts but remains clear sounding, now turn up the gain on your amp until your sub or speakers start to distort, then back it off a tiny bit.
Some people like to show off how loud their system is at 1/2 volume, when in reality it distorts at 3/4. They have the gain on their amp(s) too high. This means you will have more alternator/ignition noise (possibly) because for the same output on the speakers the signal voltage in the rca's is less.
Hope that makes sense to you.
You guessed right... gain = sensitivity
