Disconnecting battery to swap amps...Necessary?

[Nelson9937955 10+ year member]

Is it necessary to disconn the negative to car's battery when I am swapping out an amp for another?

As long as I am careful and don't touch any of the wires together, is it ok to do this?

always take neg batt off, or something to kill the loop. You even accidentally touch pos or neg to amp casing and you blow some mosfets or anything else. Don't risk it when it takes couple seconds to disconnect a battery.

I have swapped amps without disconnecting the battery, most have gone fine, as I didn't touch anything, but the last time I did it...........UM NOT SO MUCH.

I mistakenly touched the screwdriver against the casing on the amp, and SPARK!!!

Do yourself a favor and write down your settings if you need to, but always disconnect the final connection fuse. This only works if you have your "hot" wire connected to a fuse block. Otherwise, you will HAVE TO disconnect the battery's NEG.
