This most probably going to be down to your earthing point on your amp, the problem is that your sending a voltage to get amplified and the amplifier can't get rid of that much power that quickly, hence you bad earth point. Try finding a better earth point and youll be fine.

Earth point = where you ground the amp???
In America, We usually go with that terminology.

or mayb the real reason is that you most likely need to get a bigger fuse for it because 40 amps is not cutting it

before you get bigger fuses, make sure your ground and power wire isn't touching any where cuz a 20 amp fuze is plenty, you have a short some where to be sending that much watts to blow fuses like that, let me know how it works for you.

I wouldn't get a bigger fuse than what the amp came with. Fuses are a safety device as to not fry the actual amp if anything goes wrong.

if fuses are blowing that means there's too much amperage flowing somewhere. if you put a bigger fuse, that means your letting more power in your amp than what it was designed for. you risk blowing more than a fuse if you keep inserting bigger ones in.
