Gos in to protection mode as soon as you aplly power

Check for a short circuit in the wiring of the output speakers or a shorted speaker voice coil, also check for correct voltage to the POWER AMP while in use... when an AMP goes in protective mode this means two things A SHORTED OUTPUT or A INCORRECT VOLTAGE TO THE POWER AMP. if all the above is OK than the AMP is defective. are you using correct speakers OHMAGE 4, 6 8ohms??? according to your AMP.

Good luck!

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

Amp went to protect mode and will not reset to green.

Be sure the rca's are not getting severly pinched or worse you drilled a screw into them.

Second make sure your connecting the RCA's to the
1. OUTPUT of the radio
2. INPUT of the amp

if you connect any other way its wrong and could damage both radio and amp especially you screw into the RCA's your sending 12 AC Volts to ground.

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.

FUC% the protection light

i had a similar problem with my amp (although a different brand). Check you ground connection and make sure it's not grounded to metal with paint covering it. This is NOT a solid ground connection. You must remove the paint then reconnect it. Without a solid connection to ground, it cant run for very long without going into protection mode. Hope this helps

Can u help me

The amp probably has shorted outputs. Do you want to try to troubleshoot it and repair it yourself?

Aux input on Soundstorm amp

If the amplifiers have RCA jacks, you can use an adapter cable to go from the headphone jack to the RCA inputs on the amp. If you're in the U.S., Radio Shack will likely have what you need.

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.

Soundstorm 1600 Watt Car Amp

Disconnect all speaker wires and signal cables from the amp. If it powers up, the wiring needs to be checked. If it still shuts down, the amp likely has blown output transistors.
