wrong. bad connections increase resistance and lower current flow AND voltage the opposite happened.. he exceed the amount of amperage the device could pass and it failed. im not trying to be a **** B. i just dont want people catching there vehicle of fire for recommend the wrong fusing or wiring or techniques..Poor connection caused heat which caused it to fail. If it worked fine for months no problem. Put a new fuse in and make sure all connections are tight and your good to go
I think ive posted NEW charts on fuse ratings. and the proper way to test if you wire is capable of properly carrying the current.
ill post it again for evenone to see..
these charts are current tested usually via 5% voltage loss across the conductor under load.
this one is kinda unofficial but the voltage drop calculator is the thing i would look at for conductor sizing

car audio wire is very high strand count and easily handles the 90 degree wire ratings. but remember unless your distro block or battery post is pure copper it doesn't qualify for the 90 degreee rating.
most car audio distro blocks and connectors are aluminum and there ampacity decreases the total circuits ampacity.
