Same fuse keeps blowing

[rexcramer]

As thstone has pointed out, you are developing a short somewhere. The point of the fuse is to prevent an electrical fire. If you continue upping the size of the fuse, you get to a point that is referred to as a 'smoke test'. It will be obvious where the short is. It will be where the smoke and or fire is coming from. I suggest that there is a wire that has been chaffing against something that is getting progressively worse over time. Wires are usually bundled together and you risk melting adjacent wires with a larger fuse. Thus creating additional electrical problems. Start looking at wires coming through the firewall/bulkhead.

Like putting a penny in an old 60amp 1920's home fuse box. Ahh most of you have never seen a home fuse box. I'm old.

I remember that box in our garage. Screw in fuses. Even as a young kid I remember thinking the setup looked frightening.

Oh... we're not that old.

START by calculating and installing the appropriate fuse size for the stereo, as I suggested (if the 15 amp fuse wasn't already adequate). If that blows, then you have a problem.

There is no sense in searching for a short until you're sure you have one.
