Make sure you have a correct ground. Grounds will have problems doing this. Connect to a bolt, but make sure it isnt a colored one. Also make sure your rca cables arnt neg and connected to a positive :) haha

Should the amplifier go into protect mode, simply disconnect all RCA and speaker leads, while keeping +12 volt, power ground and remote leads connected.

1. Now turn the amplifier back on, and if the diagnostic LED lights, the amplifier has an internal fault.

2. If not, plug the RCA cables back, and reset the amplifier. If it goes into diagnostic now, the fault lies in the input, either with bad cables or source unit.

3. If the amplifier seems fine with RCA cables plugged in, connect the speakers, one at a time, and if one of the speakers or its wiring is faulty, it will activate the diagnostic
system.

Its on protect mode how do i take it off?


Generally if your amplifier goes into protect, you have a bad ground.
Unhook your power wire from the battery and trace your ground wire to the chassis of the vehicle. Strip the paint from the ground location, Put the ground wire back on the grounding location. Tighten the ground wire down securely with no play and hook back up your power wire.

Other cases revolve around the RCA cables.

Unplug the RCA's and see if the protect light goes off.
Plug one in and see if the protect light comes on and then the other.
If the protect light comes on, you have bad patch cables. Replace them and see if your issue is resolved.

If the amplifier was shorted, the system board made have been damaged.

The saftey red light keeps coming on


It means that the subwoofer is blown. The red light is called the Protect light. Disconnect the speaker wire from the amp and then turn the amp on and see if the red light goes away. But if as soon as you hook the speaker wires back to the amp and the red light turns on that DEFINATELY means the sub is blown.

Protect


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 . Send to Rockford Fosgate for repair .A thumbs up would be greatly appreciated if this answer is helpful to you. protect-zb4bomd1rt4qms0dqd12kkt2-3-0.jpg

I have a brand new soundstream xxx 6500d amplifier and when i installed it for the first time protect mode light come on even without rca jacks and speaker wires hooked up. any1 can help?


You need to plug in the RCA and speakers you could blow the amp. The amp is sensing no Input and No output. I would unplug the amp wait around 30 seconds then install the rca and speakers THEN install amp to battery + cable. You should be ok.

Protection Light Is Coming On


You say the protection mode only occurs when you plug the RCA's in. Does it have to be both RCAs or just one?

The other end of the RCA cable is plugged into the HU?

It possible the RCAs have too much DC voltage on them, causing the amp to go into protection.

Is there a short in the RCA cable?

I would definitely check out the RCA connection at the back of the HU, as it sounds like there could be other issues there. Make sure the RCA connectors aren't touching any other metal (especially +12V).
