i recently bought a kx2500.1 and it came with this big 300A fuse thing what the hell do i do with it the amp is 2500w rms @ 2 ohms i dont know what the fuse thing does
im a newbe here, but my guessing on an amp of that sort of power, that its a fuse for the main power from the battery. It usually comes with the wireing kit but its probably better if it came with the amp.
Put it about 10" down your power line from the battery. (this is a guess though as u haven't really described it)
The question is, what are you doing with a 2500w rms amp? There is no way you will be able to supply the needed power. With inadequate power, 2500w amp will sound as loud as 600w amp.
