    What do you mean when you state that one fuse isn't getting power?



    It sounds like the power supply in the amp is blown (or otherwise isn't producing any output). In many amps like this, the protection LED is driven by the 12v side of the power supply. It goes off after a short delay. When the power supply produces voltage for the audio section, the power led is lit.

When i turn up the volume my amp shuts down i turn it down and it comes back on. I have a crossfire vr1000d what am i doing wrong?


Hi,
Is the protect light in your amplifier turns on when it shuts down? If yes, then your amplifier lacks voltage. The reason why it goes on protect mode is, the amplifier is needing an amount of voltage from your car, since your car cannot provide that amount of voltage your amplifier is not getting anything, instead of getting voltage to produce watts its getting minimum voltage & producing heat, to save itself it goes on protect mode so the incoming power shuts off & cools the amplifier.
Example:
Your on vol 40, amplifier is working fine, when you turn it up to vol 50 your amplifier shuts of, then you put it back to vol 40 & your amplifier turns back on.
At vol 40 your voltage is 12v or above. but in vol 50 your voltage drops to 11 & below.

Check your battery or alternator if they are giving enough voltage


Hope this helps your inquiry. Have a blessed weekend.

Why is the red light that says protect on? my amp turns on but it dosent work, i have a sup hooked up & it dosent work. the red light that says protect is on.


first thing check all ground and power wires and make sure ur rca wire make sure it isnt cut in anyway. after that unplug ur sub and unplug the negative wire from ur amp, while its out check the fuses on the amp if all is well put all fuses back if not get new. then plug the negative wire back in if protect goes off check for heat and if no heat inspect the wires from speaker out put all the way to the sub, look for any wire touching another this is were most problems are even the smallest wire can trip a protect. if u still cant find the problem. an amplifier specialist is in order.if its trashed go on ebay and buy a powerbass there goin cheap right now. hope i could help

The protect light came on what do i do


Usually that light comes on by over powering the amp and sending it into protect. Usually by just shutting off the amp and turning it back on solves the issue. Some amps even come back on on there own after about 30 secs. If you have turned it off and back on and the problem still persist, try disconnecting the main power, check all the fuses on the amp and then reconnect the main power. If the problem still persist, then it is time to start looking for a repair shop, return for warranty( if applicable) or buy another amp.

My amplifier turned off while playing and wont turn on at all now


Hello, it sounds like you shorted the outputs of your amp or the power supply mosfets shorted. Very common when people have the music at a loud volume. Does the protect light come on? If not then the power supply is probably shorted not letting the protect circuit get any voltage. Some amps do this and other amps if the power supply shorts have the protect cicuit built in such a way that if the power supply shorts out the protect circuit still works. Cause you checked all wiring and redid it and no fuses blew then this is your problem. I repair amps everyday for a living. ?Most of my out of state customers are from fixya.com. I'm the cheapest amp repair business you'll find. If interested send me a private message letting me know what kind of amp it is, name and model number, and i'll get you back up and running with warranty.

Hello pimprascalz,

Many amps will go into protect mode if one of the speaker wires is shorted or grounded, or if the voice coil(s) are defective. Try disconnecting the speaker wires one at a time and see if the amp still goes into protect upon power up. Likewise, some amps will go into protect if one of the inputs is grounding out. Again, to troubleshoot, disconnect them one at a time and try the amp. Next, make sure that the amp itself is not grounding. Most amps need to be mounted to a nonconductive surface. If the case contacts the frame of the vehicle, it can cause a problem. If the problem is not in the speaker wires or the input cables, the amp case is not contacting the vehicle frame, and you have checked your power, ground and turn-on leads, then the amp itself is probably faulty.

Hope this helps.

Memphis PR300.2 Amp protect light on


If it is not turning on your problem is it is not getting power. Check your fuses. The reason an amp goes into protect mode is usually because the subs are not wired up right. Make sure your fuses are good, you have a good ground, and make sure your amp turn on wire didn't come loose when you were putting the deck back in. As for the amp going into protect you probably wired the subs down to too few ohms and the amp you have can't handle it. Try hooking the subs up straight w/o bridgeing them and turn it up to see if it works. If you don't have problems with it then you wired your subs wrong.

Mac-505 amp



Disconnect all speaker wires and signal cables from the amp. If it powers up normally (no protect light), the wiring needs to be checked. If it still goes into protect, the amp likely has blown output transistors.
