SOURCE: my alpine pdx 1.1000 amp cuts out

Power is rated at 1000x1 @ 4ohm.
How many voice-coils does your speaker have? If more then one, are the coils wired in series or parallel? How many ohms are the coils? If you actuate the cone with your hand, do you hear any "scraping" sounds?
Assuming everything above is within range and or tests good, the amplifier more then likely has at least one failed output transistor. a DMM would be needed to check for shorts.

Sounds like it's overloading you may have a sub to small for your amp cut all the settings on your amp back to minimum wind them up until sub cuts out then drop them back a bit .

My amp stays on but the sound cuts in and out. Some times it takes a good 20 minutes for the sound to start coming out after I turn my amp on. Also my sub sinks in right when I turn my amp on.


Check all connections and fuses. Also make sure your speaker can handle the wattage being put toward the speakers and the OHM load. Try a different amp to see if the same problem happens. Sub sinking in when power put to it means you may have crossed the connections Positive and negative to the speaker. Triple check that your connections are correct and your using the correct wire for the job.

I have a power acoustik ibm12000d amp had it installed to weeks ago wired at one ohm to a 15inch acoustik p3 sub worked good for to weeks hit good and everything but now its cutting off when turned up I...


Sounds like an over current condition. Your sub may be the problem. Does it go into protect mode when it cuts out? remove the sub and turn up the volume and see if it cuts out when you keep increasing the volume. If not, then it may be that the sub shorts out when turned up too much, kicking the amp into protect mode. If it still cuts out, then it may be the amp. Try another sub if you have one or borrow one from a friend.

Only when it is cold outside, 50 or below, it sticks between 2nd and 3rd gear. never happens in the warm months. I have sprayed carb cleaner in the choke area since the choke stays open when this happens


try using "Lucas Transmission Fix" it works great for that kind of problem. It's about $12 at Auto Zone and you put all of it in your tranny fluid while the vehicle is running. then drive it around for a lil bit and you should notice a difference.

Alpine PDX1.600 amp cuts off


Make sure there's no missmatched impedance. If your sub running 2 ohms then your amp has to be 2 ohms stable. Does the amp blow fuses or get really hot? If it does it can be a fire hazard and I would recommend taking it out of your car. It could be that you don't have sufficient grounding. The grounding needs to be very close to the amp and the paint needs to be thoroughly scratched off. Otherwise could be a blown transistor within the amplifier, you can check this by opening up the amp, running a multimeter and testing the transistors for resistance.

Sub cuts out


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, the sub may be damaged. You'll need to measure the resistanace of the voice coil. It shouldn't read less than ~85% of the rated impedance.

Clipping amp


hi first disconnect all spks, then turn on the amp. if amp power lite stays on bright then proceed to connect one speaker or sub to the amp. if the amp lite dims during any spk connections then it may be that the spk is faulty or there is a DC voltage (dc offset) emitting thru that particular channel. also check all spk impedance before reconnecting them to the amp. cheers.

Protect Light On Subwoofer Cuts Out


some type of over-current protect device in sub amp section gone bad..perhaps a board-mounted resettable circuit breaker or fuse has gone bad? these are hard to locate on the board for a novice.
