I have a europwer 1500 amp that we use for church services... it's the kind that fits into a rack system. It powers up, fan runs, but nothing can run off of it. I opened it up and no loose wires, nothing looks burned out. Can it be the fuses? I see two but they are all white and I can't tell if they are good or not.
COULD BE FUSES ...CHECK THEM WITH AN OHMS METER.ALSO IT MAY BE THE POWER SWITCH IT MAY HAVE GOT BUMPED AND BROKE INSIDE THE SWITCH JUMP THE SWITCH WITH A JUMPER WIRE BE VERY CAREFULL NOT TO GET SHOCKED IT COULD HAVE A 120 VOLTS AC AT THE SWITCH GOOD LUCK

It is Mossfets Transistor failure.Need s a technician to change it.
At the power Output of the amp have some power mossfet transistors.Some one or someones are Shortcircuit or a failure.It is the reason that the fan its running without working.That is why is showing you "Service"
Yes it can be done. This doesnt mean that it should be done. First thing is finding a power supply to supply power to the unit. you would need to find the size of the fuses on the amp and finf a power supply to feed that power. All home theater systems have built in amps on them. It would be much simpler to find a home theater system to fit your need. However if you insist on this setup remember to find proper power supplies and wire the system with the proper gauge wire for the amp draw. No sense in burning down the house over it.
your subs are the problem, not your amp, your wiring your subs paralelle, means dropping input ohmage, allowing your amp to over heat with minimal load, check the amp specs for running at low ohms, most hifonics amps are rated 2 ohms and higher, some however will run at 1 ohm, only on class b-a amps though.(competition) dropping ohmage will allow the amp to push more power to the voice coils, however the voice coils may not be rated for 1 ohm power, what ohmage are your coils rated at? do you have a min. of 100 amp inline fuse on your 1-0 awg wire? do you have internal fans? you can add mosfets to the amp but if you do so, you'll have to re-program your amps mother board.
How many channels does the amp have? 1,2,3,4? im going to assume its only a 2 channel amp when I say, there should be a 2 positive and negative channels, do your speaker wires off of 1 positive and 1 negative of the channels to the speaker.
The difficulty is in finding an "exact replacement" and you may just be out of luck there. But fortunately, almost any switch that can be adapted to fit will function properly. The radio shack part number 275-691 is a DPDT switch which mounts in an approximate 3/4" hole. The leads can be directly soldered into a printed circuit board or if the board has a different hole pattern, you can simply use short jumpers to the switch location.
Here's a link to All Electronics which has 35 different sizes and configurations of rocker switches. Surely one of these will work in the Mackie.
On a generic level, without knowing the specifics of your equipment, I.E. amp & mixer make/model, you start at the mixers input stage. If an amplifiers output transistors die, they usually cause the amp to trip or blow a fuse, the weakest point in the system. If the amp is not doing this then the chances are, it's an line level problem, mixer related. Again, you have to list the equipment you have in order for me to be more specific.
