If the fuse only blows after the remote voltage is applied, the output transistors are likely shorted. To eliminate the speakers as a possible fault, disconnect the speaker wires from the amp. Also disconnect the signal cables.


If the fuse blows without remote voltage applied, either the power supply transistors are blown or the B+ and ground are reversed (or they may have previously been reversed).

There could be so many things that cause this to happen. The final transistors in the unit handle a lot of current. When they fail from heat or other causes, the fuse burns out. There is nothing that you can do unless you know how to perform electronic repairs and troubleshooting. Unless you want to send it in to a shop for repairs.

I just got my PPI dcx 300.2 amp back and i hooked it all up, and connected the fuse back in and started the truck, the amp turns on but the red light starts blinking and says clip out. The amp doesnt smell...

Are you sure everything is correctly connected. If you are running the amplifier in bridge mode then take note that the load to the amplifier can be no lower than 4OHM. dreamsystems

I just replaced an amp and now the inline fuse by the battery keeps blowing

Most likely you have your power and ground connections reversed on the amp. That will cause the fuse to blow immediately upon contacting the two sides of the fuse. If the fuse stays intact for a short while but pops after turning the amp/car on and your connections are correct then there's a problem with the amplifier and it either needs to be serviced or replaced.

I got a ppi d1000/1 amp cant get any sound out of it?

Make sure your remote wire is hooked up in the right spot, also check your rca plugs and consider replacing them, check all fuses to make sure their not blown, a loose or not good ground wire or power supply wire will also cause this problem. If a power wire has a cut in it, that will also cause fuses to blow, as well as with a ground wire cut, ur amp will not be properly grounded.

3 amp fuse blows

Mark all your wires using tape or by writing it down to ensure you will be able to hook them back up exactly the way you found them. Remove all the wires from your board again. Tape off the ends so you don't "short" anything together. Identify the wires going to your outdoor unit and the wires going to your thermostat. Hook the wires up one at a time starting the with C wires and the R wires. Then hook up G. Then W. Then O. Then Y.....and any other wires you might have. Check the fuse everytime you hook up one of the wires. Remember to do the tstat and outdoor unit wires one-at-a-time will have 2 "Y" wires. Hook up only one, then check the fuse, then hook up the other, check the fuse...........Eventually, that fuse will blow again when you hook up the right wire. Then you will be able to determine the color wire and whether it is the one for the tstat or the outdoor unit. Once that is determined, disconnect that wire at the other end and re-install the fuse and restore power. If the fuse blows, the problem is in your wire. If it does not blow, it is most likely a bad control coil. More often than not, it's the wire. Look for damaged insulation and "crimps". Usually the repair can be made with simple electrical tape and/or cutting the bad spot out, using a wire nut and electrical tape, and testing it again. Let us know how you made out. If you run into another stumbling block, we'll dig deeper and walk you through it. :-)

your inline fuse wouldn't blow if there was just something wrong with the amp. the amp fuse would blow if that was the case. something is faulty with your wiring. you probably have the wires touching somewhere or are in the wrong terminals at the amp or on the wrong battery terminal. or your power wire is grounding out somewhere. its not the amp. its your wiring

Do you have a fuse on your battery to your amp wire?? If you don't that could easily happen. And make sure you have a big enough ground.

My jvc in my probe turns on but no sound i had an alpine in it before and it worked fine can someone please help me...?

you will need to find the power lead for the amp and see if there is an in-line fuse for the amp if not then see where someone hooked the amp up to the cars power source if you replace a fuse and it blows again as soon as you turn on the radio indash unit. look for shorted speaker wires or first try disconnecting all the spweaker wires and if the unit still blows the fuse you will need to have the amp checked out by a pro, unless you can use amd own a multimeter
Larry Dillon Good Luck!!!!
