Head and amp all hooked up

I hooked the head and amp up no problem. It sounds great except there is
a beating noise coming through the speakers even after i turn the key off. it wont stop until i turn the amp off?? I turn the radio up and it drowns out the beating noise? this is on an old motorcycle. What is causing this?

    I installed it exactly the way the the instructions said. Is this a manufactors malfuntion or an installation issue

  • ottome Feb 07, 2008

    my amp is making a beating sound through the speakers even with the key off. There shouldn't be any juice. I hooked everything up according to the manaul.

Hi the problem you are having is inteferance from the servo on the bike this is causing a voltage spike and this is giving you the clicking noise you hear you can try buying an inline filter this should filter out the noise for you give it a try but you should find this solves you problem let me know if you need further assistance

    if the sound happens when the key is off then it is wired up to the wrong positive wire it needs to be an auxillary wire not a wire that is live when the key is off this will cause problems as the voltage might differ slightly if the wire you are using is for something that uses alot of power but even so an inline filter should filter out any interferance your having.
    Also check the earth on the earth wire is good conection where it goes to earth out on the bike as this can also cause you problems make sure speakers are wired correct also as this will affect sound quality let me know if you need further assistance

    You could even wire the positive feed onto something like a light that comes on like a warning light any other light thats on your igntion when you switch the key on doing this will stop the unit working when the key is turned off because the last thing you want is flat battery

    i think there is some bad connection in power board of the amp.

    this is giving the bad output signal.

    this is the beating noise u r hearing.

Amp light is green getting a base like heart beat nothing else fuses are good


The only thing I'm wondering is if you shorted out the RCAs somehow. Try switching the RCA's to another output on the back of the deck, if you have more than one set.

If that's not it...you will have to add pieces of the system one by one, starting at the deck, to see if you can troubleshoot the problem. Very Odd.

Good Luck

The amp from time to time gives a tone to the speakers even when the rca audio cords are not hooked to the amp the protect light isnt on and all the wires work properly i hooked different amp to the...


You are on the right track. It's not the amp, but it is the rca wires. When you have them plugged into the stereo, you can touch them together and it will make the same sounds you described also, though I don't recommend doing that! Rca wires can be weird sometimes but usually I replace them with new ones. Even a brand new set of cheap ones will do the same thing sometimes. The noise you here is causes by either a small short in the wiring, running the rca's to close to the power wire for the amp (or any other power wire for that matter), and sometimes you can buy a grounding kit for them that is fairly cheap that will help. Most of the time for me, it was just the connections, but replacing them basically took me through all these steps at once. Just remember, you still have a chance that your head unit is the cause by the connections getting old and wore out on the inside. Hope this helps!

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.

Subs have almost no sound coming from them


Hello meow_mix_666,

If you have tried different amps and different subs with the same result, I'd definitely suspect that you are not getting enough of an output signal from the head unit. Checking the RCA's and perhaps using a different set of preamp outs would be a good idea.

One other possibility that you may not have considered is to check the phasing. I've run into speakers that had the markings reversed and running the subs out-of-phase on a 4-channel bridged would make a huge difference in the bass.

Hope this helps.

your amp may have burned out or try checking the fuse in the amp and the car also your channels may be burned or you may jus have water damage to the amp

My JL subs just dont beat like the ONES IVE HAD before as well as the ones my friends have had


sounds like they have your sub amp in mono but they put the speakers in series which totally cancels the benefit of running your amp in mono. you will probably be happier if you just hook the left speaker to left plus and minus and the right to right plus and minus. Cuz even though subs aren't directional they do pass some higher frequencies that are and that dilutes the stereo effect.

No sound coming out


I often troubleshoot these issues via a stereo head set, modify the leads so you can "Touch" them onto the Speakers Output Terminals, connect the "Shields" together, thats "Earth" and the other Two, are Left & Right... with the Amp's volume turned to about 25% volume, connect up the Earth wires to the Chassis with a clip, under a srew etc, just make good contact... then touch the Left & right wires onto the output, ya should hear sound... if not most probably the Output device(s) may have gone faulty.

Car amp's stopped working. Putting out a heart beat sound through subs but no bass.


could be low current ,disconnect all power including ground for 20min N.B most amps will seem to be shorted at output but this is normal due to damping ratio.
