Since it's an intermittant problem and a relatively expensive amplifier, you should have it checked by a qualified tech. If you keep trying to power it up, it will eventually blow out the power supply transistors which will add as much as $100 to the repair bill.

1.verify connections...Make sure your ground wire is grounded to a location on the body where you will sand the paint away to make good metal to metal contact. 2.with a volt meter check for battery voltage on the red wire of the amp as close to the amp as possible.verify that your remote or trigger wire from the radio (blue wire) id connected to the remote terminal of the amp.. turn on key switch, turn on radio and see if amp powers up. if no then verify 12 vdc at the remote terminal of amp, very 12vdc at red power wire. verify ground. If all this is good i would suspect you have a faulty amp.

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.

make sure the remote wire from the deck is in the amp but move your ground wire to a new solid metal location you may have to scrape the paint surface where the ground is going to go but it will stop protect mode and run properly (make sure to bolt it down by its self no other wires just the ground from amp) also make sure the ground wire is bigger than the power wire
hope this helped

Blowing of fuses

The reason your blowing fuses is the amp needs at the least a 150 amp fuse on the wire that runs to your bat. There are fuse blocks that you can put 4 40amp fuse and theres the high dollor ones that you can put all the way to 200amp. When you trun up your amp its drawing to much current for the little 40 amp fuse that you have and will blow it everytime. I recomend Running a 4 gage wire to bat and ground with same. Get you a 150 or above amp fuse from a car audio shop somewhere. anyway sounds like from what you decribed, theres nothing wrong with your amp just the wires and fuse are not big enouf to handle the current that your amp pulls.

If you connect the fuses in parallel yes. You can use 12v circuit breakers as long as they are the same fast/medium/slow blow speed as the fuses the manufacturer recommends.

Thing is that most standard fuses are not made to exact standards and one of the two might blow earlier than the other which then in turn wil blow. I would go for either a 40 amp single fuse made for something other than a car situation and place that in the power line or get a 12v circuit breaker

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).

Problem in ppi pcx-2400

Check the amplifiers fuses. Some amps have speaker fuses that leave the LED on if blown. Check for continuity on the voice coils of both subs. Check for 12 volts on the remote turn on line from your receiver. If all of the above are good, the amp is probably toast.

Blowing fuses under hood but nothing looks smoked in the amp

Sounds like the amp is fried, most likley in one or both of the output sections. Good luck.
