Is the power wire going to the battery? Is the ground wire short (3-4 ft) and connected securely to a GOOD metal groun source? Are you using an AGU fuse holder at the battery? Reason I ask these questions is you migh have a weak connection somewhere or a bad fuse that looks like a good fuse. When the amp is turned on, it requires more amperage that at a standby mode. Hit me back.

    OK, That's a much bette fuse link. Now,did you read the voltage at THE AMP? If you DON'T get 12V AT THE AMP, I want you to take another reading from the AMP's power to a DIFFERENT ground. If you get 12V then, you have a bad ground. Hope you find something.

12 volts to amp, when connected no volts, it turns on in my friends car.


The ampliflier require an amount to power volts to perfrom. You friends car may have a power stabilier installed to produce appropiaet supply to stereo systesm. usually, a direct wire from the engine to the amplifer may least function as manufacturers default specifcation. If the amplifer performs at all, a fuse is blown to protect the devices in wiring cuircuits. if the device functioned in another car, it is not damaged. Consult with an auto electrician to attain appropiate wirign or acqurire the component parts to wire the vehicle. Important notes. Each device usually will have an instruction on installing. However, the power source from engine depending on type of vehicle may require regulators to share the current to stereos amplifiers and speakers.

Can kicker 1000x1 amp detect if my speaker is bad and turn itself off?


The Kicker 1000x1 Amplifier does not turn off if their is an Open Line (blown sub) on the Speaker Terminals.

  1. Remove all Speaker Wiring from the Amplifier, leaving the Power, Ground, Remote, and RCA wires plugged in.
  2. If the Amplifier fails to turn on, check your Remote wire for power.
  3. If the Remote wire is powering up with the Head Unit (should be anywhere from 5-12 Volts), check your Power wire for +12 Volts, and check your Ground wire.
  4. If you are getting +12 Volts Power and your Remote wire is putting out 5-12 Volts but your Amplifier still won't turn on, it will need to be serviced.

I have my amp hooked up but it isnt getting any power can you tell me if i have a bad amp or if i need the speakers and sound for it to come on?


With all amplifiers for a car, you must have the main power connections B+ and ground connected, and then you must also have the remote turn on connected as well. This is the way the amp turns on. It comes from the radio and is usually the blue wire from the harness off the back of the radio. When the radio is turned on, the blue wire gets 12 volts sent to it so it can turn on an external device like an amplifier or the power antenna. Make sure you have this connected to the amp and that the radio is turned on. Then check the voltages at the power terminal of the amplifer. You will have the ground, the main B+ of 12 volts, and then the turn on voltage of 12 volts. If you have all of these, then you need to troubleshoot it more. It will turn on without the speakers connected, but I am not sure why you would want to connect it without the speakers. It will also turn on without the RCA cables connected for the audio input as well. But just to turn on the amplifier, all you need is those three things i mentioned. Let me know if you require any further help.

When i hook up the remote wire it makes my power wire go to 4 volts


If the battery is strong enough to start the engine, you probably have a bad connection or a defective fuse in the power wiring. If you solve the voltage problem and the amp blows fuses, it likely has shorted output transistors.

Location of remote amplifer wire


Get a DMM (Digital Multi Meter) and test the wires behind the factory radio one by one looking for 12+ volts when u power the radio on and 0 volts when u power it off. This will be your remote wire.

Your speakers probably are made for 6 or 8 ohms. to check, take out any of the speakers and read the back for the ohm rating, if it is more ohms, you need a more powerful amp.

Your battery is probably not able to supply the current needed to power the amp and your alternator is not supplying enough charging current when idling. Check these two and the wiring to the amp.
Should be some sort of decent stranded copper wiring able to handle the power consumption of the amp. When you have access to a multimeter do check the voltage at the amps 12 volt power leads and when this is below 12 volt when idling I would suspect wiring and/or alternator/battery.
