THERE ARE TWO THINGS THAT COME TO MIND WHEN DEALING WITH THESE SYMPTOMS. FIRST MAKE SURE ALL POWER CONNECTIONS, ESPECIALLY THE GROUND ARE VERY SECURE. NEXT YOU WILL WANT TO MEASURE THAT VOLTAGE AT THE AMPLIFIER AS YOU INCREASE THE VOLUME TO SEE IF YOUR POWER IS SAGGING INTO A LOW VOLTAGE BELOW 11.5 VOLTS. IF SO, THEN YOU NEED TO UPGRADE THE WIRE SIZE RUN TO THE AMPLIFIER. THE SECOND THING TO CHECK IS TO MAKE SURE THAT THE VOICECOILS OF THE SPEAKER ARE NOT DAMAGED AND PRESENTING A LOWER IMPEDANCE HIGH CURRENT LOAD TO THE AMPLIFIER, WHICH WILL CAUSE IT TO SOMETIMES TO GO INTO PROTECTION. THIS CAN ALSO AGGRAVATE SCENARIO NUMBER ONE, AS IT WILL DEFINITELY DRAW MORE CURRENT, PUTTING YOU CLOSER TO AN UNDER-VOLTAGE PROBLEM. LET ME KNOW IF I CAN BE OF FURTHER ASSISTANCE....V

Well i was driving one day and my subs just whent out so i bought brand new wires and hooked everything up but the power protector light turns red whenever uu turn it up past volume 10 i really do not know...


It sounds like your amp is going into protection. I know it's frustrating, but this is actually a good thing. If you subs you have are drawing too much power and the amp can't keep up, it will shut off instead of melting the board. Usually, the protection mode only last a few seconds. The user normally turns the music down that the protection shuts off and the music plays again. I recommend looking at a larger amp for your subs, if you are going to play them that hard.

THUNDER 5601 WHEN VEHICLE TURNED ON, SUBS BOOM, THEN WORKS OK. ALSO WHEN RADIO TURNED OFF


If the amp produces no boom with no signal input cables connected, I'd suggest using an LOC.

Let me know if you have any other questions.

Speakers All Cut out Including Sub When Music is Played Loud


UNPLUG THE GREEN WIRE FROM THE COMPUTER AND PLUG IT INTO A CD PLAYER IF IT WORKS BETTER ON A CD PLAYER THAN THE COMPUTER IT SELF THERE MAYBE A PROBLEM WITH THE SOUND CARD AND ALSO TRY THESE STEPS I AM GOING TO GIVE YOU I AM SURE ONE OF THEM WILL WORK.

1. Please ensure that the all the connections between the satellite speakers and the subwoofer are firmly connected.
2. Next, please connect the green colored 3.5mm audio jack to another audio device such as an iPod or an MP3 player.
3. Ensure that the SoundTouch remote control is firmly connected to the back of the subwoofer.
4. Connect the power cord from the subwoofer and connect it to another single power outlet in your house. If you have an automated voltage regulator (AVR), please connect the power cord through the AVR instead of connecting it directly to a power outlet in your house.
5. Power up the speaker system and check whether the power button on the SoundTouch remote control will light up.
6. Turn on the Matrix Mode ON. This option is on the SoundTouch remote control. This is to ensure all speakers from the speaker system will produce audio that will be played from the audio device.
7. Play audio from the audio device. Check and see whether the all the speakers will produce audio being played from the audio device.

IF NONE WORK TRY THESE STEPS:

Sound shuts off, sub still works


That is a common problem with this radio, for it can not go to loud without going down in volume or shutting down.
