    Is the damaged board nearer to the RCA end or is it the one nearer to the power supply teminals?

I am Maxxsonics distrubutor, they will not release the diagrams to anyone but they may sell you a new board. i have had 1 out of over 500 of the 2006 / 2008d amps do the same thing and they replaced the amp completely because they have so few extra repair parts for them (cuz they rarely fail)
here is their direct number just ask for Kellie and she will tell you what they can do for you.

My hifonics bxi1210d amp goes to protect mode 2 seconds after turn on


Overdriving the output can cause it to go into protect mode. You will not be able to restore normal operation until failed components are replaced.

800a4 stays in protect mode


Generally thats a sign of a shorted output device, either a bipolar transistor or mosfet. Also ground faults can trigger a protect light.

WHAT DO IT MEAN FOR MY AMP TO READ DIAGNOSTIC


The diagnostic light, for this particular model, means that there is either a short circuit on the loudspeaker leads or there is an internal amplifier fault that is causing a DC offset. In order to determine which, disconnect all RCA and speaker leads while keeping the +12 volt, power ground and remote leads connected. Now turn the amplifier back on, and if the diagnostic LED lights up, the amp has an internal fault. If not, plug the RCA cables back in and reset the amp. If it goes into diagnostic now, the problem is with the input (either bad cables or a faulty head unit). If the amp is fine with the RCA cables plugged in, repeat the process with the speaker cables (one at a time). When you plug in the faulty speaker wire it will put the amp into diagnostic mode.

I bought a hifonics bxi2006d new and doesnt turn on


you should not have any spark from your ground...you may want check and make sure your ground is properly installed. Try wiring the amp without the cap and see if that works.

Amp not working


sounds like the amp is going into protection mode. maybe a sub is shorted (blown). Or, the only other possibility is the mosfet transistors on the inside of the amp are blown.

!!!red protect light is on!!!


Hello beaugarcia26,

Unless the amp itself is defective, there's a short or ground somewhere.

First disconnect the speaker wires and RCA (or high level) inputs, leaving just ground, remote turn-on and power leads connected. Then see if the amp powers up normally. If it doesn't check the ground with a multimeter and make sure it is good. If the amp powers up normally, check the speaker, speaker wires and inputs for shorts or grounds.

Hope this helps.

Not a problem just a question


  • 100 watts RMS x 2 at 4 ohms
  • 200 watts RMS x 2 at 2 ohms
  • 400 watts RMS x 1 at 4 ohms in bridged mode
  • stereo or bridged mono output
  • 4-ohm stable in bridged mode
  • Tri-Way capable
  • requires 8-gauge power and ground leads — wiring and hardware not included with amplifier
  • 50-250 Hz high-pass/low-pass (12 dB/octave) crossovers
  • wired remote included for fingertip control of Punch Bass (0-18 dB boost at 45 Hz)
  • MOSFET power supply and output devices
  • MEHSA mounting technology increases the heat transfer from the MOSFET output devices to the heat sink, for higher power output, lower operating temperatures, and greater reliability
  • TOPAZ — noise-killing differential inputs that eliminate 80% of ground loop noise
  • Trans•ana circuitry keeps preamp voltages low and signal paths simple for outstanding audio quality
  • NOMAD — advanced protection circuitry for "intelligent" shutdown protection
  • speaker- and preamp-level inputs
  • 11-1/8"W x 2-3/8"H x 9-7/8"D


  • Wire your sub in bridged mode (4 ohm mono)
    + to + on amplifier
    - to - on amplifier
    (using bridging terminals)

    Power problem amp


    Sounds like its going into protect mode-try disconnecting the speakers from the amp entirely and turn the system on if it stays lit up- then ya know its the speakers (one of them at least) thats making your amp shut itself down. If thats the case look into replacing the speaker thats causing the problem.Also make sure that you have sufficient wiring to your amp - at least 8 gauge if you can. check all terminals /power/ground make sure everythings connected tight and not grounding out anywhere
