I have a pro-sound 1000 which keeps blowing plug fuses Can you let me know what fuse should be in the plug as this maybe the problem

Might be helpful to know which fuse. This may help: https://fuse-box.info/

If is a good idea to list brand, model and year of a vehicle in a post. That said, maybe these links will help although some are more technical DIY than your query is asking for:

First make sure you have the right size fuse in it look at your owners manual it should tell you what size to put in there sometimes people blow a fuse and replace it with a weaker fuse it will work for a while till they plug something in that overloads the fuse then blows and if they sell the car the new owners don't know this they just keep replacing it with same type fuse that's in it. Second make sure whatever it is you are plugging in doesn't have a short itself try plugging in something different and see if it blows then if it doesn't then you know where your problem lies.

Sounds like the amp is shoot.
Never power on the amp without speaker connected.

Might want to list it in another area. If its blowing fuses you know you have something wrong--if it (I presume it does) has an external unit for power the problem is there. Also be aware not all fuses are the same--a generic fuse like radio shack etc may even if correct amperage pop for no reason.

Either a incorrect fuse (not talking about wrong amperage) or a short in the unit--one or the other.

Hi Trevor,
A 1000W can barely supply 5A at 220V, less than 10A at 110V. So if a 40A fuse blows, there is a serious problem and you should not attempt to use this unit after it has been checked by a qualified person. Please be careful!

Good luck!

The new cost of your motor is nearly 1000 dollars, presumably there are comprehensive instructions on installation to minimise the risk of damage which could be very expensive. In particular damage to the motor control circuits due to incorrect fusing.
Do yourself a favour and contact the manufacturers directly

Fit a 3 or 2.5 anything lower, if you can get away with it, but nothing higher.
However the chances are that it blew due to an overload, often caused by a shorted semi-conductor acting like it was a piece of wire. So even fitting a smaller one and it blowing again doesn't mean it's due to the rating.

It is the fuel heater, All you have to do is unplug it.

sounds like the audio stage riving the channel has a short circuit on it.need to go through the amp stage

A ceramic fuse stands up to heat better than a non-ceramic fuse. I'm no pro, but it sounds like your power inverter board maybe bad. There are replacements out there. Good luck
