Alpine PDX-V9 no sound

I have a blue power light and the front light flickers on then off and I don't have sound. I have checked all the fuses and checked the connections, but can't get any sound.

According to the manual, the issue could be:

  • Internal issue with the amp circuitry.
  • A short on the speaker output(s).
  • Power source voltage is too high (aka above 14.5V).
  • Overheating.
The easiest thing to do is to try removing the connections to the speakers at the amp and see if the issue disappears after each set has been disconnected. Keep removing wires until both LEDs stay blue.

SOURCE: I have an Alpine CDA9884

the manual says that you should power off the internal amp if using external amps. Maybe you need to do this to get power going through the remote turn on?

in the menu its "POWER IC ON" you need to change it to "POWER IC OFF"

hope this helps?

SOURCE: red light on PDX 1.600 alpine amp... no sound

Hello zim69zim69zi,

Solid red indicates 4 possible conditions: 1) Short circuit, 2) Current too high, 3) Voltage too high, or 4) Overheated. The most common faults are the short and overheated.

If the fault is intermittent, the amp is probably overheating. If it is a constant fault, anytime the amp is powered up, then I'd recommend that you first check all of the wiring. If the wiring is OK, then you have a voltage or current problem. If it's voltage, the vehicle electrical system is probably causing it. You can check that with a meter. It should be from about 12VDC with the engine off, to about 15VDC with the engine running (alternator putting out). The amp should be able to operate OK up to about 16VDC but as components age, their values change. I'd look for a minimum of 10.8VDC and a maximum of 14.8VDC.

If the problem is overcurrent, the amp itself probably has a defective component causing it to draw too much current. It needs professional repair.

Hope this helps.

straight up. Since it has the power saving technology where it gives out the same power at 2 ohm and 4 ohm loads then u dont have to bridge it and since its a single speaker you dont have to bridge it and since it is a mono block oyu dont have to bridge it. just wire + to + and - to -.

Alpine pdx-m12 blue light fiashing


If the blue light is flashing it means the output mosfets are taking more than what the power supply can deliver. Probably just one of the MOSFETs is bad. Take off the heavy aluminum bar that is the heatsink for the 8 MOSFETs. Turn it on for about 10 seconds. (And see that the blue light is flashing.) Find the (hopefully) one MOSFET that is hot. Replace it. And you're good.

Make sure your speaker wiring does not come close to the 12v power cable running for your amplifier. If your amplifier's 12v power cable runs on the drivers side of the vehicle, run your speaker cables on the passengers side and make sure your tweeters have a high pass filter to stop any pickup of engine sound (When you are driving you *WILL* notice it at high RPM. a HPF (High Pass Filter) will also stop those nasty hissing sounds on S's.

Blown fuses


This is a sign the you have poor voltage regulation. Which may mean that you are taxing the electrical system of your vehicle. I would suggest you adding a secondary electrical supply for you audio system. This can be done by adding an extra alternator and voltage regulator and battery supply. This will allow you to drive your audio system without having it (power supply) split between the vehicle and the audio system. The fact is your system is drawing to much current for the unit and your vehicle. You are blowing the 20-amp fuses which means the the amp is creating a currnet draw which is past the rated value of the fuses, which if done too many times could damage the power amp components in the unit. I would also check the ohmage reating on the speakers connect to the unit since you may have the wrong impedance which may also cause excessive current draw and actuate some sort of overcurrent protection.

Amplifier Not powering on.


Amplifier power problems are generally pretty easy to troubleshoot as long as you have access to a digital multimeter. You need to check the DC volts on the power terminal and on the remote terminal. For the amplifier to turn on, each terminal needs to show around 12 volts. From the sound of it, I suspect a problem with your main power wire, but the multimeter will make certain. If you show voltage on both terminals (with the black probe on the ground terminal) and the amp still doesn't turn on, then there's a defect in the amplifier.
