Trying to power a amp with 16 volts. possible?


Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??

MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.

The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.

  • RMS Power @ 14.4V
    • 1800W x 1 @ 4 Ohm
    • 3600W x 1 @ 2 Ohm
  • RMS Power @ 17.0V
    • 2000W @ 4 Ohm
    • 4000W @ 2 Ohm
    More input voltage means the amplifier will have to work less hard to make power.
    Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
    With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

    you have definately blown a output channel, or power supply. Send it in for warranty.

    My ma audio hk 4000 amp is powered on no sound coming thru subs amps brand new


    If there is no protection light on, be sure the input is on. Some head units need to be turned on manually (factory set to OFF).
    Verify the subwoofers are wired properly.
    A list of your components would help to solve your problem.
    If it is new, it should still be under warranty - worst case scenario output transistor(s) blown, or power supply bad.

    Turn the system off and disconnect the speakers. Turn the system on. If the amp still goes into protection mode with no speakers connected, then most likely the output transistors are bad. If the protection light is off, hook up one sub at a time until you find the one that is causing the problem
