SOURCE: every time i hook up my coustic car amp the radio

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

Looking for info on how to hook up sub to this amp thunder4160


Hi, you have two choices for hooking up a sub to the 4160 amp. You can either connect your sub to one of the two available channels, or if the amp supports it, you can bridge channels 3 and 4 to get increased power to your sub. You have a 4 channel amp - channel 1 and 2 go to your 3-way speakers up front, which leaves channel 3 and 4 available for your sub.

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.

Coustic Car Audio 12RS Car Speaker Watts


That all depends.

I have a Sony Xplod Sub, also 12" and 4ohm, and it is a 1000w sub.

But my friend has sub that is also 4ohm and yet it is only 500w.

The ohm mean nothing when trying to figure out the wattage.

Try www.coustic.com for more info (site will not load for me)

4 plugs on each speaker i only have two wires from my amp


The reason you have 4 plugs on your sub is because it has a dual voice coil. It is basically like having 2 subs in one. You have 2 wiring options you can wire in 2ohm or 8 ohm loads. most amps are 1,2,or 4 ohm so i suggest going 2 ohm. The amp should be rated for 800-1200Watts @ 2 ohm load for this sub to work properly and make sure that amp is at max 80% by adjusting gain.This website will help with wiring be sure to note that for 2 ohm load the + are hooked up together. and the - are hooked together a parrallel ciruit.

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?
