Have you checked your speaker connections and any other connection for shorts or multiple ground loops. cause that will definately cause the protection mode.

Autotek XS-900.4 stuck in protect mode


Hi.

The amp does not go on protection only because of wiring or power source problem , but also and mainly when there is an internal fault.

Protection is started whenever an out-of range voltage value is detected from the controller circuit.

Protection can be triggered from a burnt final IC or from a speaker wiring problem.

Since you have ruled out speake, wiring and power source problems, then this Amp is probably defective

If the Amp works fine on a different vehicle, then protection mode may start either because speakers impedance is not within Amp specs, or because the amp has a too big power draw. In this last case the problem is fixed installing a capacitor on the Amp 12V line.

Regards.

Ginko.

My nitro bmw-486 amp is in protect mode how can I


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 De .A thumbs up would be greatly appreciated if this answer is helpful to you. nitro-bmw-486-amp-in-protect-mode-lv2kkrmxrai4iihdvw4m3np2-1-0.jpg

Amp goes green at first then protection.


check the impedance load or try a different ground. when you hook your ground up always make sure you sand the metal down before you connect to ensure a good and clean connection.as for the impedance, make sure your subs are wired to the right ohms. for example, if your subs are wired to 2 ohms or even 1ohm, and your amp is only 4 ohms, then it will do exactly what your saying it does.

Kicker amp goes into protection mode as soon as i turn it on


Have you tried powering on without speakers connected? Have you tried powering on with no input? If either senerio causes the amp to NOT go into protection mode, then there is most likely a short in wiring. Use a multi meter to isolate.

Amp protection


Hi, Off hand, I believe there is nothing wrong with the setup, maybe just not 100% compatible. It's just that the Sony Amp's protection is doing its job (just too good) and the stock radio is likewise doing it's job (but not too good). Just maybe, at poweron, the stock radio sends out a small burst output (maybe capacitor discharge) that we normally hear as a slight thump in the speakers which was when no Sony amp, ok. However, when you have added the amp, you also amplified the thump, which unfortunately the Sony protection reacts to. You can off course let it be since you have figured out a way to make it work or you can try and install a delay on for the power amp or separate it's power on from the stock stereo. The idea is to turn on the stereo with the Sony off and after a second or less, a manual switch or a delay activated switch will turn on the Sony. The idea is to switch on the Sony after the thump has finished. Good luck and hopes this gives you an idea. Pls post back how things turn up. Kind regards.
