    What's your guys' PSU voltage stay at?

    My voltage is at 11-11.4 volts with no music playing and then when the bass hits the voltage jumps to 11.5-11.8 but it never reaches 12. Why does it do this? Is the voltage to low? Gain is set at halfway (my receiver has insanely low preamp voltages), with the lpf on and the amp in mono. The amp is an older kenwood 4ch. Roughly 50wrmsx4@4ohms, have two channels bridged to a kicker comp 8.
    Whats your guys' PSU voltages drop to?

    Re: What's your guys' PSU voltage stay at?

    i have never monitored, nor cared what my power supply was doing

    as long as it works, im happy.

    as to why it jumps up like that, the input voltage drops, the power supply works harder to compensate and produces more voltage to create the same amount of output voltage with lower input voltage. im no electrologist, but im going to guess that the rise you are seeing is minimal and nothing to worry about

    I dont want my sub or amp to blow. I dont monitor it either, but i checked it when i first installed it.

    if you dont want to blow them, set your gains properly, and learn the warning signs.

    a > .5v increase in power supply voltage is pretty minimal. electronics can take more than a .5v variance for short times.

    I set the gains by ear. Listened till distortion and backed off a little.

    i already knew you set them by ear

    like i said, set them properly and you should be just fine . there is a tutorial about it on the forum. it is possible to do it by ear (technically), but you have to know alot more information that just when the distortion starts. you need to be able to know where the distortion is coming from (wether its the speakers, the source, the processing, the amplication, etc, etc...).

    much easier and more reliable to do it with a dmm
