Can't get my pioneer amp to power on

I have tested the battery and all the wires running to the amp with a volt meter, and it shows that there's power, how ever, when i turn my car on, the amp simply doesn't power on, can some one help me?

This happened to me make shure that you check fuse underhood/ and the fuse inside of the amp.

I just bought two ten inch JL Audios and i hooked them up and they work great.... i installed them two days ago, and since then my battery has died on me twice.... i dont know what the problem is... i...


Hi there, check when you have switched off the power in the car to see if the amp power lights are still on, if so there could be a problem with your remote wire. Check the cables to he rear of your stereo and with a test meter, determine which one loses power when the ignition key is removed. When you have found this cable, splice your remote lead to this one, and your amp should switch off when you switch the car off, thus saving your battery. You could wire it to a permanent live feed and install a switch to allow you to run the amp without the key in the ignition but dont forget your battery will run down fast because Amps use a LOT of power.

Wont turn on i bought it though craigslist


well this is what you do to check it to see if you bought a blown amp.
wire it into your car and then take a digital volt meter check to see if you have power and ground and remote turn on .


take the red lead and put it on the battery wire at amp and the black lead to the ground then see if you get 12volt to 14.4 use the amps ground for the black test lead if nothing you may have blown fuse or bad ground.

check the remote wire same way as about if you get 12 to 14.4 volt it works if not could be blown from radio or bad ground

checking the ground put the black meter lead on ground wire and the red lead on 12 volt power source if nothing a bad ground.

if your get voltage on the remote wire and battery wire and have good ground then you need to call the seller and get your money back ..

I have a pioneer gm-d8400m the amp isnt working


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.

Kicker protection light won't shut off


Hello newwithtech,

There are 4 possible causes for the amp to go into protection mode. Kicker calls it SORT for Short, Overvoltage, Reverse polarity, and Thermal. If the amp has been in and working properly, it's probably not reverse polarity. And if it goes immediately into protection when power is connected, I'd rule out thermal. So it's probably either a short or overvoltage.

1) Start by removing the speaker wires and see if the amp powers up properly. If it does, one or more of the speakers is shorted or grounded.

2) Test each pair of wires with a multimeter set to the lowest resistance (ohms) scale. Measure across each pair and from each individual wire to ground. Across each pair, the meter should read about 3-4 ohms. From each individual wire to ground, it should read infinity. If the meter reads "0" ohms (shorted) in any test, you have located the problem.

3) If the speaker wires test OK, set the meter to read DC volts and measure the voltage at the amp positive terminal. If the voltage is higher than 16V or lower than 9V, you've located the problem.

4) If the voltage is OK, remove the RCA inputs and test for proper power up. If it powers up without going into protection, you have a shorted/grounded input. Replace them one at a time to determine which one(s) is/are defective and replace the cable.

If these tests show all the wiring is good and the voltage is OK, the amp is probably shorted internally (most likely an output MOSFET), and requires service at the component level. You need to take it to your local audio shop or send it to Kicker for repair.

Hope this helps.

Power light to amp flickers on and off with a voltage of only 8


Hello goup1819,

There are some basic things that you can check without a volt-ohm-milliamp meter (VOM or multimeter), but having a meter really enhances the troubleshooting process.

I'd begin by checking the power and ground. Make sure that you have the appropriate gauge wire and that all of the terminals and connections are tight and solid. Particularly check the ground wire. It should be as short as possible and be connected to BARE METAL on the vehicle chassis or frame. Make sure that there is no primer, paint, undercoating or corrosion impeding the connection. Likewise, the power wire needs a firm connection, preferably using a ring terminal, and be a direct run from the positive battery terminal, through an appropriate fuse, to the amp power terminal, and be as short as possible to minimize voltage drop.

You can also check some of the vehicle wiring. Rusted and corroded connections can reduce the voltage going to your amp. You can loosen the connections and clean them off with a wire brush or sandpaper and then retighten them. Check and clean the connections on both battery cables at both ends, and also the cable coming from the alternator. Do this cleaning with the negative cable disconnected from the battery post.

You can test the amp directly by using a "spare" 12V battery or use the installed vehicle battery by bringing power to the amp using a good set of jumper cables and a couple of short pieces of 8gauge wire. Just be sure to keep exposed portions of the jumper cables away from any metallic surfaces and temporarily covered with plastic or other insulation. If the amp powers up properly with this direct power test, the problem is definitely in the vehicle electrical system or there's too much voltage drop in your amp wiring. If the amp still shows low voltage, then I'd suspect that the amp is defective.

Hope this helps.

Have power good ground and remote wire has juice, no sound


no you can buy a 5 dollar volt meter at walmart or autozone to test to see if your rca wires are outputing any signal/ (volts) that will tell you if its the rca wires or head unit!


thanks

No sound from the amp


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. 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 and the light stays on, the wiring needs to be checked. If it still shuts down, the amp likely has at least 1 blown output IC.

Amp just abruptly stopped working (Pioneer GM-5300T)


Apart from the external DC power fuse (I hope you have one in-line), the majority of in-car amps have 2 mini fuses inside the unit to protect the output MOSFETs from overloading due to incorrect speaker connections, ie, if the output impedence is rated at 4ohms, anything less than that is considered to be a short circuit, and will overload the MOSFETs. After performing the tests suggested by KaeZoo, open the unit and look for printed markings on the circuit board, something like F1, F2, the fuses may not look like conventional fuses.

LED power protection light not turning on


Check the fuse on the amplifier; if it's good, then you need a multimeter or voltmeter for further testing. With the meter's black probe on your amp's ground terminal and the radio turned on, both the power and the remote terminals should test at about 12 volts. If neither terminal shows voltage, you may have a problem with your ground connection; if both do, there's a problem with the amp.
