Problem could be that you need to upgrade your battery, do the "big 3" wiring by a professional. Get a kinetic 1200 or bigger to replace your stock battery, drive your car for 5 or 10 miles, and watch your amp not shut down. People just dont do the big 3, and they think their stock lead acid will hold 13 volts after the power is shut off. LOL. KINETIC.

SOURCE: i bought a 500/1 jl audio amp and also a w7 10 sub

if its cutting off and right back on then check your ground and your power wire makes sure both are connected good and none of your fuse's are blown, either that or you got a wire hooked up backwards in the sub.. but my guess is that the sub is hooked up wrong... that sub should be hooked up in a series or in parallel,

ok if your running just one speaker, it should be hooked up like this and 2 speakers are a different way...

this is parallel :pos to pos , neg to neg, then one wire coming from pos on sub to pos on amp then neg on sub to neg on amp but bridge the amp on your amp should be 2 pos and 2 neg in two different channels take the pos off the sub into the pos on 1 channel and then the neg from sub to the neg on the other channel,

this is series : on the sub it will go pos to neg then the other neg and pos will go to the amp, but make sure the pos and neg r on different sides of the sub, dont hook them both to the same coil

if your need more help give me your email and ill send you a pic of how to do it...

SOURCE: 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.

SOURCE: fuse keeps blowing when sub volume is turned up

the amp draw rating on the amp is 100 you need to put a larger fuse in, such as a 150 amp, it would be a good idea to go to 0 ga but not needed. you might also want to upgrade your altenator.

SOURCE: jl audio 500/1 amp low ohm light at high volume

I would try running the subs in parallel. Pos to Pos Dual Voice, Neg to Neg Dual Voice. Then Run + to + stereo - to - stereo on both channels.
So you have + and - running to one channel and + and - running to the other channel.
Also your LPF filter could be set too high.

B & W speakers cut out at high volume

Check the impedance of the speakers vs the impedance of the amp.


The amp needs to be lower or equal impedance than the speekers
(IE Speakers are 8ohms each so the amp needs to have an impedance of 4ohms or less)

I JUST SWAPT MY SYSTEM FROM MY TRUCK TOO MY CAR EVERYTHING WORKED GREAT BEFORE NOW AT HIGH VOLUME IT CUTS OUT PERIATICLLY BUT CUTS BACK ON BEFORE I CAN CHECK THE LIGHT ON THE AMP COULD IT BE A TUNE PROBLEM...

IF the cutting out is high volume, check the ohms resistance load of the speaker and compare that to the amp. The amp may be cutting itself rather than self destruct....

My amp keeps cutting out the subwoofer... I checked all the fuses and the wires and everything checks out good do I need a capacitor?

Your problem is probably that your amp is starving for power. I have a few questions. 1.What size wire are you using for power and ground on the amp? 2.Whats the impedance of your Sub-woofer? 3. How long are the power wire and ground wires.
For starters... I'm going to guess that you usually lose the subwoofer at lower frequencies. The lower the frequency the more power it requires to drive the sub. You also might want to check if you are running the amp bridged but mainly if your amp is trying to push a 50hz tone at high volume, If your alternator cannot provide the required Amperage. The amp will cut out. A capacitor can improve this. Run a power wire from the battery to the positive terminal of the capacitor then from that same terminal run a positive wire to the amp. Connect the ground on the capacitor directly to the body of the car...make sure to scrape off any paint to make a good ground connection.

Hi Strange problem with Marantz pm7001 When ever I turn the volume upto around 1/3 and 1/2 of the way, the amp cuts out and reset it self down to minimum volume. It seems like the amp ins't enough power...

What's probably happening is that the amplifier is shutting down or cutting back the volume as protection from damage. You may have a partial short in the speaker wiring that is not a problem at lower levels, but at higher ones causes the amp to see too low a load. There may a problem with a speaker or crossover component that is breaking down at higher volumes. Or something in the amp's output stage is unable to handle the load.

Test the system with a known good speaker system and length of wire and see if the trouble continues. If it does, you'll know it's the amplifier that needs to be checked. If the test speakers can reach normal volume, you can start checking the wiring and other speakers for the source of the trouble.

Receiver shuts off at higher volumes

The receiver may be too under powered for your speakers or the speaker ohm's may not be matched for your amp.

The reason it is shutting off is likely because the amp is becoming overloaded. At lower volumes the amp can handle the load of the speakers, but at higher volumes the power supply of the amp can't keep up with the power demand the speakers are pulling.

If you were previously able to turn the reciever high without turning off, then there is likley something wrong with the amp or possibly a blown speaker.

Try measuring the resistance of the speakers if you have access to a multimeter. They should normally read 8 ohms for home speakers, but some common home speaker impedances in order from (I'm assuming) most common to least common are are 8, 4, 2(bose), and sometimes 10 or 12 ohms. The lower the number of ohms, the more power the amp will need to put to the speakers and the more chance you could be overloading your amp.

I have a d5000 amp and its wired up to a 15.2 hcca orion sub when i turn it up high volume,it cuts out anyone know why

make sure you have the frequency cuts right. if ur giving the sub anything lower then 30hz (assuming ur using 15's) the amp will cut out to protect the woofers from overload

Radio cuts off and back on seems to be vol related

This is cause by many things one of which is a faulty speaker that is going short when operated at high volume. Another is the wiring supply the power to the radio is not "thick" enough hence not able to supply the demand for extra current. Had this same problem with Golf II which I replaced the main supply wire and after that it went to full volume with no cutting off.

My pioneer 600w amplifier cuts at high volume...

Are you sure it's not a problem with your head unit? When you mean cut off do you mean the whole amp loses power or power lights stay on but sound just cuts out? If you don't know have a friend turn up your radio if you don't have a remote and whatch the light, power light on the amp. If it goes out then it sounds like a bad ground or the main power wire is'nt large enough to supply proper power to amp. I would check those that I have described first because thats what it sounds like, bad ground or power wire not sending proper voltage. When you turn up the volume your amp needs more power well when you get to a point when you turn it up and amp cuts out or off then it's starving for power or bad ground. Let me know what you find. Also if this helps please rate my help so I can get out of this apprentice status. I have 15 years exp. and 2 degrees in electronics and my business is buying nonworking amps and repairing them then resale them. Thanks

Btw, I’m available to help over the phone in case u need at https://www.6ya.com/expert/mark_b53a7494531bf96d

SOUND CUTS OFF AT HIGH VOLUME AND POWER LIGHT FLASHED RED

You need to check the DC voltage across the power and ground terminals of the amp. If the voltage drops below ~11v when the amp shuts off, you need to check the power/ground wiring and fuses.

If the voltage remains above 11 volts, you may have a problem with the load on the amp (incorrect ohm load, shorted speaker, shorted speaker wires...).

Sony xm-1652z 1000 watt amp

a loose or corroded connection can cause this problem...do not overlook possible loose fuse holder...also look into remote control line...also check speaker line for a loose or shorted connection...a loose connection in any of these locations can cause a spike in the current drawn from the power supply... a bad speaker can play at low volume but short at high volume; if the flex wires from frame to cone on the speaker start to fail, it happens at high volume first, and sounds like a crackle, and gradually becomes present at lower levels; a voice coil can warp at high signal levels, causing it to short intermittently, in addition, you might check the cooling capability of the amp...i don't recall whether you have a fan on this amp...
