First of all, you MUST HOOK UP YOUR GROUND WIRE FIRST. You may have damaged it if you hooked your power and trigger wire first and then the ground wire. Unhook EVERYTHING except the hot wire, ground wire and trigger wire. If you still can't get the unit to come on then it is time for a trip to the repair shop. Good luck.

Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.

1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.

2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.

3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
system.

You are replacing single pole light switch?
Single pole switch has 3 wires: black and red and bare copper

New device has 4 different colored screws: green, dark, brass, silver
Bare copper goes to green screw.
Black wire goes to dark screw
Red wire to brass screw
Nothing on silver screw for a moment. Test circuit and make sure light turns on-off.
If lights works, then good so far.

Now let look at silver screw. Neutral wire has to connect to silver screw.
In back of your electrical box are white wires twisted together and covered with wire nut.
These are neutral wires.
You must connect another short piece of insulated wire to these neutral wires and run that wire to silver screw.
The neutral wire will complete circuit to receptacle.
If you do not have neutral wire, then receptacle will not work in that box without additional wiring.

Hook up neutral wire to silver screw.
Now turn on power and click switch again.
If circuit breaker trips, then reverse your red and black wires.
Otherwise this should be correct wiring.

Well, I have no idea why you would have two capacitors on a 500 watt amp but, did you charge the capacitors? Have you tried the amp without the capacitors? What size power wire are you using?

The saftey red light keeps coming on


It means that the subwoofer is blown. The red light is called the Protect light. Disconnect the speaker wire from the amp and then turn the amp on and see if the red light goes away. But if as soon as you hook the speaker wires back to the amp and the red light turns on that DEFINATELY means the sub is blown.

Yes, keep in mind that the amps have a constant power (the large red wire) and need a remote signal to tell them when to turn on/off. This wire connect to a switched 12v from the ignition or radio blue wire (if aftermarket)

I'm replacing a single pole light switch with a timer switch and the timer switch comes with a hot (Black) and a Load (Red) as well as the netural (White). My question is how to wire it up. Does the white...


It all depends on how the light on the pole is wired. The switch you have is meant to interrupt the power between the circuit breaker and the light, just like the switch does now. The new switch uses power to run itself, so you need an additional wire. Usually the lights on a pole have the power coming in on top, and a wire coming down for the switch - black and white. Lets say there was no switch - on top of the pole there would be a black wire going to the hot, or center contact on the pole light, and the white wire would go to the ground, or outside of the bulb. If (BIG IF) things are wired like they are supposed to be, there will be a black wire (hot) coming in from the breaker, down the pole, instead of going to the light. The switch you have in place now interrupts the power so you can turn it off/on. Then when you turn the switch on, power goes up the white wire to the hot, or bottom of the bulb. Theoretically, there should be another black wire going back up to power the light once it leaves the switch. People normally use regular wire, which has a black and a white inside a plastic casing. So, bottom line - you need to run a red wire from the light to the new switch, hook the white wire up to the ground. So: power coming in on top goes down pole to new switch to black. Red wire hooks up to pole light where it is now white, goes down pole to red on switch. Old white wire gets unhooked from light on top, and hooked to common (ground) on top.

It jus turns off an i can't figure out y?


Disconnect the speaker wires and signal cables from the amp and measure the voltage across the power and ground terminals with a multimeter.

With the black meter lead on the ground terminal of the amp and the red meter lead on the B+ terminal of the amp, the voltage should remain at or above 11 volts.

With the black lead again on the ground terminal of the amplifier and the red lead on the remote terminal of the amp, the voltage should again remain at or above 11 volts.
