Check your ground and make sure it is properly grounded ....it needs to be a very clean paint/gum free area tightly bolted.  Next Check and make sure you are recieving your 12 volts (not running)  13 (running)    by placing your test leads from positive to ground...... then make sure your power remote from your head unit is putting out voltage.

Do i have the right fuse


This speaker at full power draws average 1.3A at 230V and 2.5A at 120V. Mackie's recommended fuses are in line with this so your fuse is actually too high a rating. It is possible you are using cheap fast blow fuses or are over-driving the speaker (which should cause the fuse to blow) These speakers are only capable of 118db sustained (@1M) so cannot be expected to cope with anything but small venues or gentle music.

2001 buick lasabre fuses keep blowing now the car has no power


Obviously a blown fuse is caused by a short to ground. You may need a book to get the wiring diagrams to trace the circuit.
Does the car start then blow the fuse after you put a new fuse in ?

What causes fuse #5c in my 1996 buick park ave. to keep blowing?


A fuse that keeps blowing is probably the result of a wire that is grounded unintentionally. This would be the result of an exposed power wire touching the engine or body and grounding out. This would cause an excessive power draw and blow the fuse. The other option is that the fuse was lower amps than the original one. check the fuse diagram to see if the amps match up.

My 2002 f350 diesel keeps blowing the fuel pump fuse every couple of miles. What is causing this? I changed the filter and it made it worse.


the problem could be the fuel pump fuses only blow when they are overloaded ie. if you have a 15 amp fuse & the fuel pump or whatever is drawing 20 amps the fuse will blow,if you are using the right amp fuse the fuel pump is drawing too much power & may be faulty or there is a problem with the wiring, a loose connection or the like.....hope this helps....cheers

Roland KC-550 blows 500ma fuses in power supply for no appearent reason. Why does this happen and are fuses correct value?


Fuses blow when there is an overload. This is caused by a faulty part in either the power supply (such as transformer or any semi-conductor -diodes, rectifier, IC, transistors etc) or in the main amp stage - anything on the heat sink. The most common cause is a semi-conductor acting like it was just a piece of wire. A cause of an overload alsot is a speaker wire shorting, which blows out the transistors on the heat sink or whatever is on there, they in turn blow the fuse!
Whatever value fuses is put in will blow! The higher the rating however could cause something to get hot thus causing a fire, before they do go!
If the 500ma fuses where the originals marked on the end cap, then stick with them. Often it is writtten on the PC board too.

Replace fuses No power on no standbyby power LED Just nothing


Are you trying to say it's blowing fuses? Stop wasting fuses and risking a fire.

Disconnect the speakers, see what happens. If it keeps blowing fuses it needs a real pro to look at it. Internet doesn't help.

I keep blowing fuses on my 1989 acura ledgend


What circuit? Check the owners manual and see what all is powered by the circuit that blows. For example - the dome light and cigarette lighter could be powered by the same fuse. A dirty element on the lighter could cause cause shorting that would blow the fuse and put the dome light out. The symptom that you notice might not be the cause. You could also have a wire that has damaged insulation that is shorting to ground and blowing fuses. Faulty or worn parts could cause blown fuses.
