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

Deh-x6500bt cuts out at high volumn

I have the same problem, it's only when the bass comes in, and it starts to cut at half volume.

My wiring is correct and every possible problem to do with the car and its wiring have been eliminated.

-Apart from plugging the unit into another vehicles loom.

Pioneer a-602r amplifier cuts out at high volumes

It is more than likely the final output transistors in one or more of your channels are beginning to short out or fail.

Bass cut off when volume is too high

When an amplifier shuts the Bass off that means its going into protection mode otherwise it will burn out the outputs. One way is to turn your gains down, Pioneer amps are not the best amps for bass out there, they are more for car speakers, I personally wont use a pioneer amp to run my subwoofers especially if they are hard driven subs like JL , Kicker Solo's and MTX subs. But for now just turn the gains down to 3/4 and that should help u, you can also install a fan to keep your amp cooler, if this never happened before in 5 yrs and now it does then that means your amp is just tired and the inside components are overheating easily, thats common with Pioneer and Sony amps.

Good luck buddy.

Volume cuts out, volume knob overloads when touched

If this is the old style potentiometer unplug amp and remove cover to get to volume control. spray contact cleaner made for that purpose at the radio shack stores or similar. Spray it into the control and turn the control back and forth to work it in. Let stand for a few minutes and try it again. Always make sure it is dry on all components first.

Subwoofers don't work all the time.

I've had similar problems in the past with speakers. The most likely culprits are 1) over excursion of the subwoofer. If you have the bass boost or gains set too high, the speaker recieves a distorted signal,the amplifier would likley read this as an open vioce coil and engage protection circuitry. 2) a voice coil on the verge of collapse(same result as above) 3) your amplifier is running at too low an impedence(some can only bridge into a 4 ohm load) and is over heating. You may be pushing the amp beyond its ability, and it is over heating. or. 5) the amplifier has faulty internal circuitry(least likely but I had a brand new amp with a dozen cold solder joints on the printed circuit board) and is cutting out as a result of inadequate electrical transfer.

Why does my KAC-8404 cut off at high volume bass?

amp 101

1/0 wire to the amp or the amps will loose power

check the connections mainly the negative

wiggle the wires see if you get a cut out or not

a cap will help you give constant power to the amp and not allow them to drain on long bass notes

hope this helps

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...).
