Uhhhhhh....... So my amp stopped working. Everything checks out alright.... the blue LEDs are on but the power light doesnt come on. The Red (protection light) LED comes on when i first start the car but only for about 5 seconds.Help Please, Thank You,

Re: Protection Mode? amp wont start
With your multimeter set to DC volts and the black meter lead on the ground terminal of the amp, touch the red lead alternately to the B+ and remote terminals as the amp shuts down. If the voltage drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low.
If the voltage remains near or above 12v, disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

Dhd amplifierDisconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Double check all connections .A thumbs up would be greatly appreciated if this answer is helpful to you. Worth fixing.
DID YOU CHECK YOUR FUSES? Is there anything lighting up on it to see if it is in fact turning on? If it's lighting up and there is no protection lights lit up then check your speakers to make sure you didn't burn them up. If there is a protect LED lit then unhook your speakers and see if it stays lit or not. If it stays lit then check to make sure you're getting enough voltage at the amp connection, minimum of 11.0 volts is required just to get it to turn on. If it has under voltage and over voltage protection LEDs see if they're lit. If you do all of these things and are getting enogh voltage, your speakers are not burnt, your protection LEDs are lit no matter what then you need warranty repair that amp. If your speaker wires are shorted it will make your amp shut down also, but since you were using it for a day or so my bet is that you burnt up one of your speaker voice coils and it's internally shorted and that will cause your amp to shut down in protect mode. Otherwise you probably internally fried your amp by too low of voltage or not enough current (amperage) due to not large enough conductor (too small gauge wire) should be minimum of 8 Ga. for each amp, 2 amps will require 4 Ga, 3 or more will need 2 Ga, or 0 Ga. wiring to keep the voltage and current flow high enough to keep from damaging the amps. Good Luck!
Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty. Using an ohm meter to the sub will confirm whether its bad or not. Invest in a cheap test set of 6.5" speakers.

When you press the Power button to start the boot process, the LED lights glow while the computer verifies that there is sufficient electrical power to activate the hardware.
& Solution: When you press the power button, the LED lights on the
computer do not glow or the LEDs blink briefly and then stop. There is
no sound of the fan or hard drive spinning, and the screen remains
blank. The computer will not start if there is insufficient battery or AC adapter power.
The BIOS queries various hardware components used for the startup boot process.
& Solution: When you press the power button, the LEDs glow but
there is no fan or hard drive sound. The LEDs may glow briefly and then
The LED lights blink, stop, and then blink a
second or third time, but there is no sound from the computer and the
screen remains blank. The sequence of the blinking lights indicates a
specific error code.
A series of beeping tones is heard. The sequence of beeping tones indicate a specific error code.
a hardware component has recently been replaced, or if the PC has been
jarred or shaken, there may be a loose connection to the memory chips
or hard drive which prevents the computer from starting.
The BIOS loads the basic input (keyboard) and output (advanced LEDs / display screen / boot drives) devices into memory.
& Solution: When you press the power button, the LEDs glow, the fan
or hard drive sounds, are heard, but then the boot process stops and a
black screen - with an error message - displays.
The boot check has detected a communication error or conflict with a hardware component that must be corrected.
The BIOS loads the Windows operating system and starts the services
that allow low-level control of all of the background operations.
& Solution: When you press the power button, the LEDs glow, the fan
or hard drive sounds, are heard, the HP or Compaq Logo displays on a
black screen, but then the boot process stops and a blue screen - with
an error message - displays.
The boot check has detected a hardware driver error or a software conflict that must be corrected.
Control is transferred to the Windows loader to initiate the display of the advanced settings in the Windows environment.
The Windows logo displays during this step.
& Solution: When you press the power button, the computer performs
all the steps in the boot process, but after the Windows Logo displays,
the moving Windows progress bar or the rotating cursor stops moving and

An error message may display on a screen with the Windows logo. In some instances, there is no specific error message.
A black screen appears and the computer attempts to restart.

flashing light could mean a few different things. 1- constant power may not be there. check with a test light or multimeter. should read around 12 volts. it would be a good idea to check all the power and ground leads. make sure u have a good ground. 2- bad sub. im assuming sub since its a monoblock amp. you can meter the subs. make sure the total ohm load is no less than 2 ohms. any lower the amp will go into protect mode. 3- bad amp. power supply may be bad. the newer pioneer amps are full of protection circuits. ive been a professional installer for a shop about 8 years and we sell pioneer. hope it helps.
disconnect all of the speaker wires at the amp and turn your system on -if the amp stays on then you likely have a roasted coil in one of your speakers somewhere and causing a short which is shutting your amp down into protection mode-if the amp wont stay on with nothing connected to it then you have probably roasted something inside the amp and uhhh good luck bro
Hi, what you need to do is unplug all the connections to the amp. The amp goes into protection when the circuitry over heats.\
First decrease all your gains to minimal volume.
Connect your 12+V, remote, and ground.
See if the protection light comes on then.
Next plug in your RCA cables.
Check protection light.
Then plug in your subwoofer cables.
See if you are still in protect mode.
Hopefully everything works alright again.
Just slowly increase the gain to see what the cut-off is. Make sure you aren't dropping the ohmage too low on the amplifier. Check manual for correct wiring and such.
