hi guys, does anybody know why a class D amplifier keeps blowing fuses? I read a post about this topic but i think this is a little bit different because thi is class D. The only reason i think it is not workning is because i had a subwoofer with double coil in parallel. The thing is that i guess the speaker was not working properly . The connection was right because the minimum resistance is 2 ohms, so i had this speaker with two coils in parallel giving a total of 2.
Well, any comment. By the way the amplifier is MTX so if anybody has a schematic or something please let me know.
 

If you have problem only with fuses, maybe they are rated for to low current or they act to fast ..
Try to use "slow blow" fuses or increase their current rating by one step, for example, from 5A to 6.3A ..

Regards,
