With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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.


If the voltage remains near or above 12v, disconnect all speaker wires from the speaker terminals of the amp and disconnect signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.

What size is the amp and how many watts is the speaker(s) you have it ran too? If your speakers are trying to pull too much power from the amp it will turn itself into protect mode to keep from blowing a fuse as well as if you are pushing to many watts into small small speakers it will do the same to protect from blowing the speakers I would recommend turning the settings on the amp down slightly and then trying it out also make sure your wires arnt crossed adjusting the setting as it plays is the easiest way to fix the problem also make sure the bass isn't all the way up on your head unit

I have a Legacy Predator 2000 watt amp with 2 12'' Kicker speakers. It has been in my car for about a year now, and it recently just stopped working. I have the green light to the amp, im not sure about...


If you have checked your ground, live, remote and RCA's, The problem may lie with your kicker speakers.
There may be a loose wire connection on the speaker terminals (hense no sound).
Check the terminals at the speaker (+) and (-) then check the speaker wires to your amp inputs.
Usually if there is a fault with any wires linked to your amp, the amp goes into protect mode.
If your amp is not going into protect mode, try linking a different speaker to each terminal on your amp (left) then (right). If you get sound through a different speaker, more than likey your speaker wire to your kickers has came loose (due to vibrations) or there is a break in your speaker wire.

Hope this helps. If any more info is needed I'd be happy to help more. Please rate if helpful

My amp keeps goin into protection


Normal 0 false false false MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman"; mso-ansi-language:#0400; mso-fareast-language:#0400; mso-bidi-language:#0400;} Your amp is probably OK. The volume is either set to high or the speaker load is to low of an impedance. Remember 2, 8 ohm speakers connected is the same as 1, 4 ohm speaker. Another possibility is that you do not have enough battery power coming to the amp itself. A simple rule I use is take the watts and divide by ten, that will give you an approximation of the amps needed on a 12 volt system. This takes into account some of the losses in the amp, but it is only an approximation. For example 300 watts RMS is 30 amps, which will require a number 8 wire to keep the losses at a minimum. You can check wire drops on the web.

Good Luck,

Well is their any ways to fix a car stereo amp??


One of the more confusing things with a car stereo can be when the amplifier goes into protection mode. One minute it's working and the next minute it's not. Here's a brief troubleshooting method that will hopefully help you if your amplifiers ever go into protection.

1. Try to determine the cause. Amp's can go into protection mode for several reasons. Knowing what happened before it cut out can help determine how to fix it. Did the amp not work as soon as it was turned on? Did it happen after blasting for hours (may be thermal overload and it needs to cool)? Did it cut out after you hit a bump (a wire connection may have come loose)?

2. Tear it down. Get the amp down to it's most basic state. Remove all of the speaker wiring and RCA wiring and leave only the power, ground and remote leads connected. If you still have a problem in this state then either your amp is defective or you may have an installation problem such as the amp touching metal.

Remember that an amplifier should only be connected to the vehicle through the power and ground terminals. Mounting the amplifier to the metal of the vehicle, including putting the mounting screws into metal, can cause problems for your amplifier. Always mount the amplifier to a non-conductive surface. An easy way to accomplish this is to mount the amplifier to a wood board and then mount the board to the vehicle.

3. If the amp is OK in this torn down state keep adding the other wires back on until you find what causes the problem. Add the RCA cables first. Then add the speaker wires one at a time. If the speaker wires cause the problem then they are probably touching metal. Check to make sure that a speaker wire isn't being pinched somewhere between the amp and the speaker. Also check that the speaker wire or speaker terminals aren't touching the vehicle metal near the speaker opening. Rear decks and door panels can easily touch unprotected speaker terminals if not properly installed.

If the problem starts occuring when you connect the subwoofer wires to the amplifier you may have your subwoofers wired at too low an impedence. First check the specs on your amplifier to make sure what kind of loads it is stable under. Then go here and check the wiring configuration to make sure that your load is not too low:

If you believe your amplifier is defective contact the manufacturer first. Many have flat repair rates that are very affordable and cover parts and labor. However local repair shops may be cheaper if it is just a small repair. Compare the manufacturer's repair rate to that of a local shop. If you don't know the reputation of the local shop it may be better to send it to the manufacturer who will have working knowledge of the amp and parts readily available.

Kicker amo in my old vette


If the amp is in protect mode, it probably has shorted output transistors. To eliminate other possible problems, do the following.

With your multimeter set to DC volts, the black meter lead on the ground terminal of the amp (not on the point where the ground wire connected to the vehicle) 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 drops below ~11 volts, you need to check the wiring feeding whichever line is dropping too low when the amp goes into protect.

If the voltage is OK, you need to check the speaker wiring and the speaker(s). Try it with a known good speaker if possible to see if the amp works normally.

2006 12" Kicker L7 4 ohm


first whats the range in terms of WATTS that your 12" sub can handle in 4 OHMS ? second , lets check the AMP , POWER ACOUSTIK 1800 WATTS , Now thats a lot of power to drive a single 12" sub speaker . your amp is 1800 watts , per channel is around 500 watts , if BRIDGE thats around 1600 watts rms for ONE channel , if your sub can handle that kind of wattage fine , but it will not blow the amp , what it does is shuts down , some kind of protection mode , it will come back on after a minute or so. I suggest to use one channel in stereo mode , or purchase another sub to use the other channel. i hope this helps AJ

Lanzer vibe 416 1000watt Amp stay in protection mode completey


I'm no pro but I've fixed a few amps in my time.When you had the 12's hooked up it was working fine you say,but when you upgraded to 15's is when the problems started. You probably bridged it too low of ohms and it maxed the amp out,it got too hot and started to burn up the channels. all that matters when you buy speakers and amps. The 12's was probaly 4 ohm coil speakes and the kickers are 2 ohm. The kickers bridged together positive to positive, negative to negative would bring it down to 1 ohm load witch I dought the lanzar can handle. If your a fix it yourself kind of person like me. I can point you in the right direction on where to looke for parts to fix your amp....

Rockford Fosgate 501bd question


that amp should work fine with those speakers,just make sure that they(speakers)are wired for 2 ohms.at 500-600watts coming from amp, you should be getting 250-300 watts per speaker,just dont crank your gain too high on the amp.
