Disconnect all speaker connections and rca cables. Leave power, ground and remote wires intact. Try turning on again. If you still have a protection light your amp is faulty. Hopefully you have warranty D .A thumbs up would be greatly appreciated if this answer is helpful to you. hello, i have a nitro - nitro-lv2kkrmxrai4iihdvw4m3np2-1-0_0.jpg

Its because to be honest. its not that good of an amp. im not bashing your choice bro, but cheaper amps use cheaper components inside, which means the little parts get hot and tell the amp to protect itself from burning up and go into a standby mode.
maybe you have loose wires in the speake rbox, which are bouncing around and making it short, or your trying to jam too hard and the amp is just getting too hot. its probably in your trunk or under your seat and that dont help the amp at all. it needs to be cool when its on,

turn down the gain . i know it makes it bass more, but your over driving the amp, which makes it get hot faster.
if the amp is good quality amp, then maybe your speakers are not strong enough to handle the power and it makes the amp hot because it cannot get rid of the power thru the speakers like its supposed to.
turn the gain down, use bigger wire to the speakers.
the amp will also get hot if you dont have enought power for what it needs. maybe you need a 1 farad cap between your battery and the amp on the red wire. the cap holds extra power so the amp dont struggle to get 14.5 volts from your 12 volt battery.

My nitro bmw-486 amp plays but want put out loud sound


I have the same exact amp. And my friend has the smaller 1600 watt amp, and this happened to his. Basically, just start from scratch. Unhook every single wire, and rewire it. If that doesn't work, look at the side of it, and there are a few knobs that you can adjust using a philips head screwdriver. Try adjusting the bass boost knob.

Nirto bmw-486 Tech Specs


Generally, this type of amp is relatively simple to repair if you're capable of replacing the blown parts. If you can find the web site for Nitro, you may be able to get a schematic. I couldn't find their site.

What troubleshooting have you done?

What parts are blown?

If you need help troubleshooting, I'd need a photo of the inside of the amplifier.
