MAKE SURE THAT YOUR POLARITY IS OK FOR THE SPEAKERS.TRY TO TEST THE VOLTAGE BEFORE STARTING THE ENG THEN AFTER AND SEE IF ITS THE SAME OR MUCH MORE.

I have an Alpine M500 mono amp that works great, until you turn up the volume. I can adjust the bass down at the head unit, but at higher bass the amp shuts off. And then comes back on after a couple...


I don't think either, I believe your running theamp load too low with too low an ohm speakers and this cases the amp to produce more power but not stable and it overheats and the thermal protection cuts the amp off when the temp gets too hot to prevent damage.. Make sure your speakers depending on how they are wired do not exceed the amps load rating

Sub cutting out


Check the 12v wire running from the battery to the amplifier. Also the sony explode is a garbage subwoofer compared to the Alpine.. sony (they say 1200w max but its more like 100w to power the thing) Amp could be going. Is the amplifier hot when running. If there is a burnt smell comming from the amp, its the amplifier

Amp gets power but no sound


Hello, First of all with these new Alpine amps everithing adjustable just about is digital, as well as the internal workings of the amp to a point. If you bought this amp new then check your warranty or take it back where you purchased it if you can. Check that your amp is getting an input signal from your head unit. Check your head unit sub output settings, something could have gotten turned off or down. On this paticular amp if there is a problem internaly it would let you know or go into protection mode. You say your sub has ben tested and is good, check again. Hook another speaker up to the amp. Unhook that speaker and try, you never know. Like I said, if the amp is'nt going into protect mode and the digital display is'nt telling you any types of faults then it has to be the input signal. Make sure you are getting a signal. That has to be your problem otherwise amp would be in protect mode. Let me know what you find.

Amp powers on, no sound from subs


the output is blown. It is in need of service.
There are many different ways that an amp can fail but the two most common failures are shorted output transistors and blown power supply transistors (< those are not blown). There are several types of protection circuits in amplifiers. The most common are over-current and thermal. The over-current protection is supposed to protect the output transistors. Sometimes it doesn't work well enough to prevent the failure of the output transistors but it will work well enough to shut the supply down before the power supply FETs are destroyed. If the amp remains in protect mode, goes into protect mode or blows the fuse as soon as the remote voltage is applied, shorted output transistors are almost certainly the cause.

Amp went into protect, but front speakers sound distorted too


If the amp still goes into protect mode, the easiest thing to do is disconnect the RCA cables from the amp and see if still goes into protect mode (after turning off/on). If it does, the issue lies in the amp or the wiring to/from the amp (most likely case). Check to make sure no speaker wires came loose and touched +12V or ground (car body). From the sound of it, my guess is something internal to the amp died and will need repair.

Amp goes to protect mode only on cd play


Do you get adequate bass on the radio, or is it a bit quiet on the low-end?

Amp staying in protection mode


No, this amp is not a heavy power consumer- matter of fact it takes very little power to run.Maybe you should check the fuses on the amp to see if they are what is recommended.Also check your fuse kit to your amp- your fuse might not be big enough.If neither works take it back where u got it.
