My phoenix gold x200.4 amp turns on but the protect light keep on flashing

Check the voltage at the turn on lead into amp..use another switched power source .they sell relays for 5$...or another switched source...

DID YOU CHECK YOUR FUSES? Is there anything lighting up on it to see if it is in fact turning on? If it's lighting up and there is no protection lights lit up then check your speakers to make sure you didn't burn them up. If there is a protect LED lit then unhook your speakers and see if it stays lit or not. If it stays lit then check to make sure you're getting enough voltage at the amp connection, minimum of 11.0 volts is required just to get it to turn on. If it has under voltage and over voltage protection LEDs see if they're lit. If you do all of these things and are getting enogh voltage, your speakers are not burnt, your protection LEDs are lit no matter what then you need warranty repair that amp. If your speaker wires are shorted it will make your amp shut down also, but since you were using it for a day or so my bet is that you burnt up one of your speaker voice coils and it's internally shorted and that will cause your amp to shut down in protect mode. Otherwise you probably internally fried your amp by too low of voltage or not enough current (amperage) due to not large enough conductor (too small gauge wire) should be minimum of 8 Ga. for each amp, 2 amps will require 4 Ga, 3 or more will need 2 Ga, or 0 Ga. wiring to keep the voltage and current flow high enough to keep from damaging the amps. Good Luck!

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 . Please check speakers impedance .A thumbs up would be greatly appreciated if this answer is helpful to you

wat i would do was just check all ur connections and fusses first

More than likely a blown output transistor. Phoenix can send you a schematic for that if you email their tech support. Be careful if you decide to work on it yourself.

Hello www_wallyeva,

The most likely causes for an amp to go into protection, is a short or ground on the output terminals.

Remove the speaker wires and see if the amp powers up normally. Check the speaker wires and voice coils with a multimeter to locate a short or ground.

Hope this helps.

It's normal for some amps to go into protect for a few seconds when initially powered up. If it remains in protect mode, it may have shorted output transistors. To eliminate other possible causes, read through the following troubleshooting page:

Let me know if you have any other questions.

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 . Remember to disconnect all power including ground for about to 1/2 hour to discharge capacitors. You might get lucky and get a reset. .A thumbs up would be greatly appreciated if this answer is helpful to you.

Check to see if the fuse is blown. If it's not, the amp is unfortunately fried. It would not be worth repairing the resistor in it
