    Icon32 input sensitivity setting mistakes on JL XD600/1

    Hi, this is question/post about some mistakes that I've made setting gain on my JL monoamp. This is my first aftermarket car audio system, which means I'm a complete newb, so please bare with my ignorance while I catch up to speed. I'm using a Pioneer headunit, JL XD600/1 monoamp, JL 10w3v3-4ohm subwoofer, everything was self-installed.

    I followed JL's input sensitivity procedure to set the desired output of 40v at 4ohm. I turned OFF all processing/eq/bassboost/loudness, set HU volume to 30 (range 0-40), set HU subwoofer level to 4 (range -15-6), played the 50hz tone, while adjusting the gain screw until my DMM read 40v AC. I was happy with the results and put the cover back on my amp.

    Then I turned on EQ, set Loudness to MID, but did not realize that I will need to readjust (downward) the gain. I listened to my system this way for about 2 days, and then decided to check the voltage while playing a 50hz tone at my highest listening volume of 22, (range 0-40). The output voltage was 51v, the recommended is 40v. What is the likelihood that this caused damage to my amp/sub?

    Since then I've decided to disable loudness, and repeated JL's procedure with EQ on, so now my gain is set correctly.

    Thank you

    If it had damaged anything things would have stopped running properly. You are probably fine.There has to be a kind of perfect storm to blow things. Overly aggressive settings won't necessarily do it by themselves if you don't actually blast it for extended periods of time.

    and nobody cares what your sub is.
