Question about Coustic Car Audio 481QE Car Audio Amplifier

1 Answer

Car Amplifier Hello: I have a Coustic 480 car amplifier that has a problem. The amp will come on for a second or two then shut off. This happens frequently. Sometimes it will stay on but it has become more off than on recently. The power light goes from red to green while this happens. I have checked all connections and supply voltages. Woofers connected to the amp are good. I feel that the problem is internal. The amp does the same thing cold. Any idea what this problem could be? I have experience in replacing circuit components. Thanks.

Hi - You can download the manual by clicking the link underlined in blue below:

So the startup red led shows an over current condition, if your sure the speakers are OK then you will need to go "under the hood". The best start for this is the following web site:

Can i run my amp at 1ohm and how


You should look your amp up online to see if it can handle 1 ohm stable....most can't. Lower ohmage does make the bass hit harder but can heat your amp up pretty gd....if your amp can handle it you may want to get a capacitor if you don't already have one.

Sound turns on and off. Green light sound, red light no sound. It is like playing name that tune. A few seconds of music then off then on and repeat. It is not the deck as it has meters showing output. The...


Amp is probably going into protection mode, or does not have enough current from the power wire to continue operating. Check that the speaker wires are not shorting out against each other. Also check your power wire and ground wire. Ensure that the amp is solidly grounded. Are you using the proper gauge of power and ground wire? (4awg recommended.)

Amp is wired but power light not comin on


it might be cheaper to just buy a new amp then to fix it cause i would go for MTX or coustic cause its almost the same company. Coustic is made by MTX and the price is good for the quality.

Every time i hook up my coustic car amp the radio will turn on with out the radio on


THE GOAL HEAR IS TO DETERMINE IF THE INSTALLATION IS CAUSING YOUR PROTECTION FAULT OR IS IT THE RADIO OR AMPLIFIER ITSELF HAVING INTERNAL DAMAGE. REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL POWERS UP ON ITS OWN, THEN REMOVE THE REMOTE TERMINAL COMING FROM THE RADIO. IF THE AMPLIFIER SHUTS OFF, THEN YOU MAY HAVE A SHORTED TURN-ON TRANSISTOR WITHIN THE RADIO AND IT IS OUTPUTTING THE DC NEEDED TO TURN THE AMPLIFIER ON. IF YOU REMOVE THE REMOTE TURN-ON FROM THE RADIO TO THE AMPLIFIER AND THE AMPLIFIER STAYS ON, THEN THIS POINTS TO A FAULT WITHIN THE AMPLIFIER AND IT WILL NEED TO BE SERVICED. MAKES SURE THAT THE AMPLIFIER AND RADIO GROUNDS ARE 100%. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

I have a kenwood kac-728s and two coustic 10in. subwoofers hooked to it and every time i start my car and the radio powers on the two 20 watt fuses on the amp blows.any ideas?


That is pretty much saying that the amp's power supply is shorted or at least has a low resistance path to ground which is causing the fuses on the amp to blow. The amp has protection circuitry to prevent damage to the output stage so that is not what is causing this. Is the amp new?

Coustic 601se power on but bad sound


This is generally caused when there are blown output transistors but that generally causes the fuse to blow or causes the amp to go into protect mode.

If you connect a 15 amp fuse in series with the main power wire and it blows when remote voltage is applied, the amp is drawing excessive current. The problem could be either in the power supply or audio circuits.

Do NOT apply power without having the transistors clamped TIGHTLY to the heatsink. They can fail in seconds when there is a problem. The heatsink helps protect them.
