I am putting a subwoofer in the trunk of my 850. The sub manual suggests 12 gauge wire with 25 amp fuse. I was thinking of finding an unused fuse in my fuse box and wiring through there when I noticed the power antenna is on a 30 amp fuse. Wow! I'm thinking, maybe I can use existing wiring and just tap into the power antenna wire in the trunk to power the sub.

This seems too easy. Am I missing something? I get that the sub running at high power at the same time the antenna is going up/down could blow the fuse but that seems unlikely.

FWIW the sub is an Infinity Basslink. It is not a big high-powered amp that needs a battery cable-type power source.

The fuse box explanation for the fuse I am talking about says that in addition to the antenna it serves "power to caravan/trailer". This sounds like the circuit has capacity beyond what the antenna needs, for connecting to a trailer. Maybe there is even a trailer connector in the trunk, just waiting for me to use it (where?).

Thanks for your ideas,

Terry
