Amp blows fuses "immediately"... HELP

I have had this amp installed for about 8 months working without a problem. Now all of a sudden it is blowing fuses as soon as I hook the power, Ground, and switch wire up Conneting no speakers.. it blows the inline 30a fuse. I have no clue what the problem could be, as I have never experienced this... I am taking it to a audio store today to have them test the amp. HELP..

Re: amp blows fuses "immediately"... HELP

For this to cause a problem with amplifiers there is something internally wrong with it. Most of the time the mosfets take a shit from the atmosphere its put in by all of us audio people. If it still has warrenty that would be the easiest route to go. Send it in to them and have them fix it for FREE lol!! well sorta. Hope this helps you understand why you are blowing fuses.

So i hooked up the amp useing the pre-existing 8 gauge wire with a 30 amp fuse it worked for about and hour and started blowing the 30 amp line fuse. i replaced the line from 8 to 4 gauge and installed an...

this sound like a case of arcing power wire it happens very very easy if u use cheap wire especially from walmart. whatever u do keep using fuses and get a batt test asap. if u take out the fuses ull burn the amp like no other and plobably burn out the power rails which will be cheaper to buy a new amp after that

Fuse blows right away when powered on... either my power line fuse or my amp fuse. I have a kenwood amp atm and it doesn't blow the power line fuse so it has something to do with the phoenix gold amp....

Verify that there are no obvious shorts in the supply power to the amp. It is likely that a major short is in the amp itself therefore the fuse blows immediately. Check the internal areas of the amp for obvious signs of a short. If you are not familiar with this consult more qualified help. This may also be of help to you:

Blows the 30 amp fuses

yes you have a internal fault of the amp. the circuit that puts it into safe mode is bad and that is a very small chip on the board know as a op amp. needs to be repaired.

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.

Amp blows the fuse every time.

it aint the wire, the bigger the better.
try checking your ground, if there any rust clean with sandpaper. if your gain and freq is cranked it will blow fuses and cut out, cuz the protect mode kicks in

Ground zero amplifier overheating and going into protect.

Since you changed the amperage of the fuses and the cable, you allowed the internal problems of the
amplifier to get worse than they were before the original fuses started blowing.

A fuse is a safety instrument that blows instead of your amplifier.

The problem is NOT the fuses frequently blowing, as such events warn you of internal problems with
the amplifier which you should have had serviced at the time to prevent them getting worse.

It is very much like the persons who replace the fuses in their household wiring with pennies, to prevent
frequent fuse replacement only to have their house burn down from overloaded circuitry.

Service your amplifier immediately.

Revert to the original amperage on all fuses in your vehicle to prevent a car fire.

Blowing fuses

Are you sure you don't have the positive and negative power wires reversed?

Does the fuse blow without remote voltage applied?

40amp fuse blows

Measure the DC voltage across the B+ and ground terminals as well as across remote and ground. If you have less than 11 volts when the amp tries to power up, the amp could be shutting down due to low voltage.

If the voltage remains near or above 12v, 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 or blows the fuse when you apply remote voltage (turn the head unit on), the amp likely has blown output transistors.

What eq settings do i need

Hello ed4037, If you are blowing fuses this means that you are drawing too much current check your impedance value on your amplifier it should be 8 ohms to match the subwoofer's 8 ohms of impedance. In addition make sure that you have the proper value fuses. In other words you should not be tuning the amp not to blow fuses, because you should be able to go to full amplitude on your amp without blowing anything. As I alluded to this sounds like an impedance mismatch problem. I hope this helps, Thank you, Shuttle83
