Fuse size vs amplifier output

[power-fanatic07 5,000+ posts]

You fuse the wire for the capacity of the wire anyhow, not the draw of the amp. Having too small a fuse is just as bad as having too big a fuse, it needs to be fused correctly for the wire. Ive seen people who run a small fuse that gets really hot but doesnt blow, and it will actually melt the fuseholder and anything around it.

Yeah this is total BS.

Engineering-wise, fuse for the lowest common denominator.

If, for example, you have 4 gauge wire and you know your amp won't need much more than 60A, fuse the wire for 60A.

Car audio wise, do whatever the hayell you want, because regardless of what's right, that's what people will do anyway.

Case in point:

Fuses add resistance. //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif I run no fuses.
