Question about Kicker KX120.2 Car Audio Amplifier

Blowing the amp fuses

I ran wires in my 99 dodge ram for this amp. One directly from the battery for a 12 volt supply, one from the cigar lighter power for the remote. And one ground directly to the body via self drilling screw under the carpet. With a good fuse in the amp, as soon as I go to hook up the last of any one of those wires the fuse pops immediately. Where did I go wrong? Or have I caused damage to the amp.

Re: Blowing the amp fuses

Do you have speakers connected as well? do you have a volt meter
make sure you are getting + from both are you sure the remote is not a 5 volt line?

After tapping into the ignition wire to connect the remote wire for a amplifier the 15 amp fuse keeps blowing when I try to start the car. What should I do?

a car amplifier should use an outdoor 2or so gague (very thick_) wire, ran, not to the fusebox, but to the battery, with a 20-30 amp under the hood, within a foot of the battery. the amperage your fuse will rewquire is based on the formula amps= wattsdivided by volts. a 240 watt amp on a 12 volt line would need a 20 amp fuse, just for the amp alone.

It keeps blowing my fuse for my stock radio. Pushing a 10" sub.. Fuse on my amp is good. In-line fuse is good. But it keeps blowing the radio fuse in my panel.. ? Please help.. Thanks Ryan

Check the amp turn-on wire. It's a blue/white wire running from the radio to the amp. It's probably label REM at the amp. This wire sends a switched 12 volts from the radio to the amp. It is probably shorting out somewhere between the radio and the amp.

Wont turn on. everything should be connected properly, got new fuses to make sure. It worked fine until i dismounted and disconnected it from the battery. When i reconnected it, no luck it is a Autotek...

Make sure this high powered amp is not mounted directly to the chassis of the car. Mount it to a wooden board and you can screw board into the car. Because some very high powered amps can arc and damage itself.

Next make sure the tubular fuse in the hood is not bad it may look good but internally it got real hot and caused a bad solder connect in the fuse. You can test it with a meter. Measure one side then the other side if the 12 volt is going thru the fuse.

Next step is now you know your amp is getting 12 volts from the car battery but do you know if your amp turn on signal is turning on the amp itself. This is a easy test get a little wire and jump the 12 volt to the amp turn on wire if the amp comes on then you have found your problem. The amp turn on voltage is too weak were ever youve connected the signal. Normally you hook it up to the blue/white wire on the back of the radio first. If it doesnt have one hook up to the blue. Now on some very rare occassions the voltage drops when you put a load to it and is not enough to turn on your amp you can easily see this if the voltage across the blue wire goes below 12volts so hook it up to the red ignition wire so at least when you turn on your radio the red will send 12 volts to the amp to turn it on and will not drop in voltage. You see that wire has to be 12volts when it drops the amp will not turn on. Same with the battery Voltage you have to maintain 12 Volts or higher for the amp to operate.

Kenwood KAC-729S keeps blowing fuses. Checked all cables, re-ran power, remote, and ground. All good, still blows them at power-up.

Hello opey_69a,

Here are the troubleshooting steps for fuses blowing.
1) Remove all wiring except ground, power and remote and see if the amp powers up without blowing the fuses. If it does, the problem is in the input cables or speaker wiring.
2) The use of loudspeaker impedances below the recommended minimums will cause the amp to draw excessive current - check.
3) A shorted or grounded RCA cable may cause the fuses to blow - check.
4) If an amplifier fuse blows continually, with only +12 volt, ground and remote leads connected, the amplifier is probably defective, most likely shorted output MOSFET's. In this case the amp needs professional repair or replacement.

Hope this helps.

Amp blowing fuses

Your amp is blowing fuses to protect your circuit. The type of 12V battery does not matter. For whatever reason you are over driving the amp. 2 Ohms sounds like a very low impedance for a car amplifier output. I am assuming you have the two 12" speakers wired in parallel. Most are rated at 4 Ohms which means you are pulling twice the current with the 2 Ohm load. Also, the bigger the speaker, the bigger the magnet, the bigger the coil, the larger the inductance, the heavier the load. Make sure these speakers are matched with your amp. A small amp driving large speakers will shut down at high volumes. Try putting them in different channels. Good Luck.

Trying to power a amp with 16 volts. possible?

Golf carts do not have a charging system. If you are going to use battery power only, why not just add (1) 12V car battery instead of (2) 8V??

MA Audio runs (ran) their bench tests @ 17V. All the power ratings advertized are at 17V.

The power supply for the hk4000D is unregulated. So the more voltage = more power.. 8V-16VDC.

  • RMS Power @ 14.4V
    • 1800W x 1 @ 4 Ohm
    • 3600W x 1 @ 2 Ohm
  • RMS Power @ 17.0V
    • 2000W @ 4 Ohm
    • 4000W @ 2 Ohm
    More input voltage means the amplifier will have to work less hard to make power.
    Don't expect the amplifier to work for very long however. the current drain on a class D amplifier is huge. There are no on-board fuses protecting the power supplies, so be sure to have at lease a 150A power line fuse.
    With 150A current draw - even with the amplifier at 1/2 gain - expect to get 10.6 minutes of listening time from your 16 volts before recharging - also note, the amplifier MUST see 8V to turn on, there is a built-in voltage sensor that will shut down the amplifier if voltage is too low.

    Car amp blows 12 volt wire fuse

    the wire from your battery is blowing fuses? and you are using 20-30 A fuses? mine has a 100A fuse..look into getting new wire plus my wire is 4 gauge.., 1600 watts is too powerful for a 12 g wire and a 30 A fuse

    Amp Light Won't Stay On

    Sounds as if you either have some bad wiring probably on the 12volt side or a major problem with the amp. Seeing as how it's new I'd be taking it back to the retailer. I just hope you didn't reverse the polarity of the 12 volts or maybe put 12 volts up a speaker output. That could mess with the warranty somewhat. Are you sure you have the 12 volts connected to a good solid supply and the earth a good one too. I always ensure any heavy drain equipment is connected directly to the battery with heavy duty wiring and well fused. BMW
