Check for shorts to ground in the speaker wiring, the speakers themselves, total Impedance, especially woofers. Proper size power and ground wire and all connections. Use a Ohmmeter or find a friend with one that knows how to use it, If all else fails RMA .
Good luck, sumthin

What do you do when your amp keeps blowing fuses


First off which fuse is it? The inline fuse from the battery or the amplifiers power supply fuse? Blowing the main fuse from the battery is caused by either the load (your amp) drawing too much current or you have a short to ground somewhere. Maybe there is a tear in the 12Vdc line and it is shorting to the chassis of your car. If the amps power supply fuse is blowing as soon as it turns on your amp has a shorted power supply. This will require internal component changes by a technician. If it is blowing after operation at high volumes I would say change the impedance that the amp is driving. If you are at 2 ohm try to rewire your speakers for four ohm. (go from parallel to series wiring then bridge mono or operate the amp in stereo mode)

I have an spl gorilla series 1250watt amp that blows fuses


REMOVE THE RCA INPUTS AND DISCONNECT THE SPEAKERS, THEN POWER THE AMPLIFIER UP WITH THIS NO INPUT, NO SPEAKER LOAD CONDITION. IF IT STILL BLOWS THE FUSE, THEN IT WILL NEED TO BE SERVICED. IF IT BLOWS THE FUSE BEFORE TURNING IT ON, THEN YOUR PROBLEM IS IN THE POWER SUPPLY SECTION. IF IT BLOWS THE FUSE AFTER ATTEMPTING TO TURN IT ON, THEN YOUR PROBLEM IS PROBABLY IN THE OUTPUT SECTION. ALSO KEEP IN MIND THAT THE P1'S ARE REALLY NOT RATED FOR THAT MUCH POWER AND YOU MAY HAVE DAMAGED THE VOICECOILS. BEFORE REINSTALLING THE AMPLIFIER, MAKE SURE TO CHECK THE SPEAKERS FOR SHORTED VOICECOILS OR YOU WILL POSSIBLY DAMAGE THE AMPLIFIER AGAIN. LET ME KNOW IF YOU NEED FURTHER ASSISTANCE.....V

Fuses keep blowing


if the inline fuse is blowing, you are putting out more power than what is getting to it, thus overloading the fuse and blowing it. Try a bigger fuse first and if that doesn't work, you will need to get a larger guage power cable with the bigger fuse. Also check your ground is properly grounded.

I have a 25 wat fuse in my power wire connected to my amp and i keep blowing it. should i put a bigger fuse in it?


Hello grabert205,

You do not say if the fuse blows immediately upon powering up or while the amplifier is operating. If it blows immediately, I'd check the power and ground.

If it is blowing the fuse while operating, I'd try a 30A and see if it holds. At maximum output of 100 watts times 4, the amplifier needs about 31 amps of current at 12.8V. So driving it hard could certainly blow a 25A fuse.

Hope this helps.

Pioneer Car Stereo blows fuses


You have a short on the right side of the vehicle, you mention a fuse to the right channel speaker keeps blowing which tells me that either the speaker is blown or the wire running to it from the deck is touching metal somewhere. Check the wiring, or install a different speaker and see if it takes care of the problem. When you turn right the system goes off then back on tells me that there's a short. Check all of your stereo related wiring.

Keep Blowing Fuses


Sounds like the amp is shorting somehow. You are obviously shorting out somewhere between the battery and the amp. Are you sure you grounding location is a good one? is the fuse blowing only when you turn the stereo on? Something is not hooked up correctly.

If the fuse at the battery is blowing then it's a short.

If the fuse on the amp is blowing then its probably a bad amp.

Blowing fuses


Here are some answers:

1. Make sure your amp does not have a higher amp rating then the fuse, For example, an 18 amp amplifier will blow an 15 amp fuse, so connect it to a 20 amp fuse

2. you have a connection issue, where something is shorting out

3. you are pushing the amp or car to it's limit with how loud you put it, and thus blowing it, fixed by getting a more powerful amp and a better fuse.

4. or there is something very wrong and cannot help you and you would have to bring it into a shop.
