It sounds like it's going into protect. To be sure it's not the wiring, disconnect all speaker wires from it. If the light still goes out, check the DC voltage on the B+ and remote terminals. Place the black meter lead on the ground terminal of the amplifier. If the voltage remains above 11 volts as the amp tries to power up, the output transistors are almost certainly shorted causing the amp to go into protect.

My pyle plmra 220 600 watt 4 channel amp blew out, pyler said it would be 50 dollars to send it in to them so i said to heck with that and oppened her up and found a capacitor blown, but when i replaced...

outputs also blown, go to ebay and buy a better amp form the same price you would have paid for pyle to fix that one, just keep playing with that one and you will get better at repairs, thats how i learned to fix amps.

JVC 600 watt amp overheated

Yes it has a protection mode, let it cool for while then try it again, if it over heats quick make sure you're not running the amp below its stable impedance.

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)

    V12 MRV-1507 or Xplod? Amplifier - XM-ZR1252 good quality sound

    Alpine is just a better brand in general. I have the older MRV-1507, sounds GREAT, i have had friends who has had the Explode line, but it was always a temporary system until they got something better, like the alpine or kenwood.
