Ok, I had this problem before. If there is a metel part of the car near it, connect the neutral wire to it,. basically you are re-inforcing the ground and it should not "hum" anymore.

The speakers just pulse when you plug in the rca jacks pn a sony xplod xm-zr1852


Depending on the amp, you may have a bad ground on the rca's. The best way to determine if you have a bad rca ground it to run a wire from ground to the outside ground of the rca. If it stops pulsing, you have a bad rca ground in either the amp or the head unit (radio).

I wanna put it into my car myself but dont know how and was hoping for a lil instruction


you will need a amp install kit witch comes with a 15 ft patch cable power line for amp and a blue line for remote. these wires run from the radio to the amp. The blue wire is called remote it turns the amp on or off depending on the radio state. the patch cable is rca jacks on both ends the back of the radio should have the female part of the rca jacks hanging from it. The other end goes into the amp. and last but not least the heavy red wire will go from the battery to the amp usually there is a fuse holder that you need to put between the battery and the amp. As far as grounding just ground the amps negative to the car chasis some where.

Good Luck Hope this helps

Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty . Send to Rockford Fosgate for repair .A thumbs up would be greatly appreciated if this answer is helpful to you. protect-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

Hum sound when plug in. if i touch the input jack the hum sound disapear.


The best way to test your sound problem is to buy another pair of patch cables/RCA cables and try those, most likely you have a ground loop in the RCA cables, basically you are creating a ground when you touch it.

My kicker zr240 powers up but its no sound coming out the amp the guts of the amp looks fine


it could be your input section on your amplifier were you rca jacks go in but you should check and make sure it aint your cd player out put on your rca jacks the easy way to check this is with a meter and a cd playing in your cd player turn your meter on volts usually your out put on rca 2.5v some cd players put out 5v so take your postive tester needle and stick it in the inside part of your rca jack and take negative tester needle and touch the outerside of the rca jacks and see if you get any reading if do that good on that part but on your amp no it could be in the input section of your amp it could be as simple as a burnt trace wire on the bottom circuit board or a op amp chip theirs alot in a amplifier but you can test them with a meter to find out witch one bad but i would take it to some one that work on amplifiers if you dont know how to test them

You have a Direct Short in the System Between the Head Unit and the Amp. Check the Ground on the Amp and then Check all the Wires behind the Stereo and the Common Ground There. You could even have a Spot in the New RCA Cables that is Touching Metal Somewhere. Please Rate My Response! Thanks!

Protect Mode with RCA's


It sounds like you have some DC voltage on the RCA input.

You need to figure out if the problem is coming from the head unit or if it is in the amplifier.

If you have a voltage meter, you can use it to find out very quickly.

Set the meter for DC and for a max level of more than 12 volts. Most meters I use have a 30 volt level. That would be a good setting.

Take the black lead and make sure it is grounded to the chassis of the car or to the ground of the power terminal, be careful and make sure it does not touch anything else.

With the RCA cable disconnected put the red lead on the inner part of the RCA cable and see if there is any DC voltage and then check the ground or outer part of the cable. Do the same for the other channel as well.

It should be very close to zero volts. A couple of millivolts is fine to. Any voltage here will cause the amplifier to go into protect mode, which is what is happening to you. You will then need to have the head unit serviced.

If you have a Pioneer head unit, I have seen many of them with an open ground fuse for the RCA jack. That fuse is a surface mounted fuse and is very small and hard to locate on the main board of the radio. If you do have a Pioneer head unit the voltage may seem OK, but you will have an open ground, but that normally does not put the amp into protect. It makes the audio sound very weak and you would have a loud hum. I can help you with that if it turns out to be the problem.

If the voltage on both the RCA leads is OK, then you need to check the amplifier.

You can put the meter lead on the ground of the RCA jack on the amplifier, if you have anything abnormal there, you have a problem in the amplifier. Be careful checking this because you can easily touch the lead to the chassis of the amplifier at the same time as the RCA ground. Most of the time, if yu have a problem in the amplifier like the one you are having, this check of the RCA ground will result in some DC voltage on it. If it still checks OK, then put the lead into the RCA ground and check the positive part of it. You may need to move the lead around a little to get it to touch the metal inside, it is on the bottom part of the hole inside the jack.

I think you will find that you have some voltage on the RCA inputs of the amplifier. To fix this properly you will need to take it in to be serviced.

Sometimes you can ground the RCA jack ground somehow with a jumper wire and then turn the system on with the RCA cable plugged in and it will seem normal. But you do not want to do that as a repair, only to see if the amp will play. If it does play, you know that the problem is in the pre-amp of the amplifier. That would be the only reason to connect an external ground to the RCA jack. You still have a problem in the amplifier. If it does not play normal, you still have a problem in the amplifier if there was some DC on the RCA jack.

Sorry this answer is so long, but the problem you are having will require service of one of your units, you just need to know which one it is. If your inputs get grounded, you will not have the amp go into protect, you just won't hear anything.

Let me know if you need more help and if this was helpful to you a good rating is always appreciated.

Cant figure out my car audio problems!!!!!


There are a couple of tests you can perform. I'd first recommend checking the shield ground. You'll need an ohm meter. The details can be found on the following page.

RCA shield ground test

You can also test the output with the multimeter. Set the multimeter to AC volts. If it's not an auto-ranging meter, set it to a voltage range of ~2v AC. Disconnect the RCA cables from the head unit. Touch one meter probe to the outer ring of the head unit's RCA jack. Touch the other probe to the metal contact in the center of the RCA jack. With the head unit near full volume and a clean signal source, you should read at least one volt on musical peaks. If you have a bass disc or a test tone disc (~60hz sine wave), use those.

Can't get my amp to turn on


You need to confirm that you have sufficient B+ and remote turn-on voltage.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp and the head unit on (so the amp will have remote voltage applied), touch the red lead alternately to the B+ and remote terminals of the amp. If the voltage is below ~11 volts, you need to check the wiring feeding whichever line is too low.
