Your remote turn on not working,you can run accesory power off fuse panel that works only when when key is on or accesory ,then amps will work when car is running or on accesory. Then when you turn car off amps will turn off.

I have a pioneer GM-X524 amp connected to a TS-W253C subwoofer and it isn't working. It has 12v power to it and a solid ground, but the power light wont come on and the sub isnt working


there should be 3 power related cables connected to the amplifier:

1-From battery to amp via fuse (positive)
2-From chassis of car to amplifier (negative)
3-From head units (power continuous) (blue or blue/white cable) to the amplifiers remote connection.
this connection enables the amplifier to switch on when the head unit is switched on and off when the headunit is switched off.
I hope this helps and let me know if I can further assist you.

Connected a Dual XPA2100 300 watt amp to the battery and connected ground to chassis of vehicle. Vehicle is 2004 Saturn Ion with battery located in trunk area. Amp does not power on, all connections are...


The remote wire DOES need to be connected to the head unit. You can see if thats the problem simply by touching the remote wire to the power wire. The unit should come on. The head unit should either have a remote lead, or a power antenna lead, and thats what you need to turn the amp on and off. BE SURE your ground is solid, and its usually best to take that to the battery as well to prevent unwanted engine noise. Hope this helps!

I have good power and ground connections but the amp will not turn on.


Make sure the fuses aren't blown. There should be fuses on the amp itself and an in-line fuse in the live power wire near the car battery. If the fuses aren't blown, make sure the remote wire is connected from the head unit. Then re-check your power and ground connections. The ground should be solidly connected to the vehicle chassis in a paint-free location.

APX200.2 Marine Power amplifier. Problem: No audio, No power light on amp. 12V to amp is good, fuse not blown. Head unit works.


is the remote power good? also, make sure you have good ground(grind the connection clean if connected to chasis). If that don't work and the fuses on the amp are good, then the amp is blown.

Subs and amp dont work


His amp probably blew your fuse. Check that you have 12V at the power connections. If you don't, then find the fuse in your positive wiring to the amp. If you do have 12V to the amp, check your remote power up also has 12V between that and the negative line when your head unit is on. If it doesn't, then it's probably an internal fuse in your remote switch on line inside your head unit caused by a fault in your friends amp. This is normally accessible at the back of the head unit.

Power off issue


Hello octoberburni,

No it is not normal for the amp to stay on when you turn the ignition off. And yes, it will definitely drain your battery if this condition is not corrected.

Use a multimeter set to volts and check between the ground connection (right connector) and remote turn-on connection (center connector) on the amp itself. You should have approximately 12V when the ignition and your head unit is on. And 0V when they are off. If you measure voltage when the ignition and head unit are off, either the incorrect wire is connected to the remote terminal, or the defect is in your head unit. If you measure OK, that is voltage present when ignition and head unit are on, and no voltage when they are off, then the problem is most likely in the amp itself. If you find voltage on the remote wire all the time, check to see that it is coming from the correct output from the head unit. Most aftermarket head units use a blue or a blue/white wire for the remote amp turn-on lead. Many (most) stock OEM receivers do not have a remote amp turn-on lead. But they may have a power antenna lead which will serve the same purpose. In any case, just insure that the correct wire is connected to the amp. It should have voltage when the head unit is on and no voltage when the head unit is off.

In either case, if everything else is still working with the amp, you can simply wire in a manual toggle switch to turn the amp off or on whenever you desire. A SPST (single pole-single throw) toggle switch is what you need. If the problem is in the head unit wire, put the toggle switch inline with the remote wire and mount it somewhere handy on or near the dash. If the problem is not in the remote wire, you'll need to put the toggle inline with the main power wire, the one marked "12V" (left connector) on the amp. In this case, you need to make sure that you have a heavy duty toggle switch, one that will handle more amps than your primary fuse. You may need to look under the hood for the fuse to check it's value.

Hope this helps.

AVIC-Z1 options just quit


It actually sounds like you don't have your parking break wire (light green wire on wireing harness) grounded. I have an 06 F150 and the same thing happened to me when I instaled it. I had no address search and some other functions didn't work as well. Try to locate the light green wire and ground that to anything metal. Hope this helps, the install manual isn't very good at describing this.

No power


Hi,

Other than the +12V, the ground (-) and the 2 RCA inputs, normally external amps have also a remote trigger which switches it to active on. The remote trigger is activated by a wire from the head unit. Colors would either be yellow or blue but depends on manufacturer of head unit. Alternately, you can connect a simple toggle on/off switch to activate the external amp.

Additionally, pls verify that the 2 RCAs from your head unit are audio out and not audio in for aux source.

Good luck and kind regards.

It not turn on


Not sure what kind of connections you have, but be sure your unit is recieving good clean power. Try using another 12v constant and possibly a good 12v switched power source. Double check your ground wire as well. The unit may also be broken and might need service.
