Bonnie and others
the sub is in the back corner, not under the dash as someone said. It has a 15 amp fuse.
the power to the woofer is fused at 10 amps through the 15 amp auxiliary port
speaker wires connect in either kick panel.
stereo was off at time of smoke, it still works fine, and no fuses blew
a 2nd mod is a wire connected to each side yellow flasher, the rear brake bar and the left tail light - for trailer lights. These four wires are protected by a commercial isolation circuit that pulls its own power for trailer lights. This 12 v power is the same as the woofer and can only be used when not "woofing". This was not powered when supercharge smoke occurred.
anyone who has done car stereo knows that all this wiring is on the 12 v side, and I double fused in series. i know better than to go anywhere near the high powered side. I have rebuilt 3 EVs.
To be complete, other mods are a decal on the rear bumper that says "all electric", I attached my license plate with suction cups and J hooks, I have a cell repeater plugged into the auxiliary with an antenna on the roof, I plug my iPhone into 5v auxiliary. I have an eco hitch attached. I was not pulling a trailer at the time of smoke.
I specifically did NOT run a power wire to the fuse box as Crutchfield recommended and others have done. I did not want to exceed 10 amps to the woofer.
I measured 3 amps draw by the woofer to be sure I was not close to limit. The repeater is rated at 1 amp. My iPhone is less than 1
amp.
No. This was not outside smoke.
No. This was not steam. It was electrical burn smell.
And Tesla did imply that my wiring could somehow be involved. They suggested no more changes.
Any other questions?
