Blows a fuse after about 5-10 seconds of being powered on. I took out the amp from my truck(that works just fine) and hooked it up there, and have the same problem. I think its in protect or somthing is shorted, just wan't to know where to start.

The point of the fuse is that it blows before a surge can damage anything past it. If there's a component that could be damaged with a 3 amp surge for example, the 2.5 amp fuse would blow before the surge gets there but the 3.15 would let it through, and damage would be done.

Awz8812 blows fuse


what 13 amp external fuse are you speaking about? if this is a power line fuse feeding the dryer then its way too small normally you use 2 30 amp fuses or a 30 amp tandem pole breaker to power the receptacle where the dryer plug plugs in

Amp blows fuses


Are you using the correct fuse? if so,
more then likely, you don't have a good ground. Try grounding to something else that has more direct connection to your frame. If that doesnt work, try getting larger power cables.
I had the same problem with my 2500w xplodes all I had to do was get a thicker cable for the ground and battery connection. What was happening, was it was needing more power then the wire and fuse could handle, so it would blow the fuse, since the higher you have it, the more power it needs to feed the watts.
I would try grounding it directly to the frame on a good part of the frame before spending another $70 on new power cables though.

I Hooked up a Performance Teknique 1200 watt 2 channel amp to my 2 12" comp kickers. and before doing all this i took out the fuse. from my car battery. after everything was hooked up i put the fuse back...


disconnect the amp and then put the fuse in.if it blows,there is a pinched wire causing a short.
Also,big amplifiers like that have to be wired battery direct.
the surge current at boot up can pull 100 amps for 10 millisec.

Pyle PLA885 amplifier blows 25amp fuse. Ideas?


signs of a short, did any wires touch while you where hooking or un hooking the amp? if not then the internal power supply probably has a short in it and needs to be repaired. you can swap the fuse for a good one and hook it back up and make sure you don't touch any wires and if it blows it again then your issues is internal and will need repair if it doesn't and everything seems fine then wires could have touched or the amp was ran past it's limit and blew the fuse to protect it self. good luck and ask any more question you have

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!!!!

Sounds like an overload, amp switches on, can't get enough juice and switches off. Get a friend with a volt meter to measure the voltage at the amp power terminal as you turn it on, if it drops below 10.5v the amp hasn't got enough juice. Some amps can cut out before the fuse blows, so you never know it's an overload. I'm not sure what you mean by a 'power slide door'

Beer Spilled on my Power Acoustik PS2-820 Amp


Hi , now that you have the amp apart , just check the underside of the printed circuit board and check for any corrosion ,rub it with a soft brush . then try connecting without speakers . see if it still blows fuse, if it does then there is a likelihood that your mosfets / outputs may have shorted the first time you reconnected it . Good luck
