you need to start typing in English before anyone can help you.

By short i mean that one of your power wire may be stripped and is grounding out on the chassis of the car.

alright cool its a really short amount of wire so i should be able to find it, if thats it

also if thats not it should i just put in 25 amp fuses instead on just replacing my 20s all day?

Do not upgrade your stock amp fuses! They are already designed/sized to be 20% over the amps max power so you should not be blowing them.

Check the power/ground connections to make sure they aren't arcing.

If you are replacing the fuses constantly it won't be long before you fry the amp.

alright cool

ill just strip my power and ground wire out tomorrow and redo it and hopefully itll solve the problem.

well i checked all the wire there are no shorts >

not sure what it is, im going to set my gains again and maybe that will fix my problem if not im dropping fault on my amplifier but i opened it once it first started blowing fuses and there was no visible damage anywhere.

any other suggestions on what my problem might be?
