What would be the best way to send a wire from the engine compartment to the passenger bay? 2002 mustang v6. i'm just wiring 2 12"s in the back and i got it all workin i just need to run the power wire through to the battery.

couldn't find a post for this on the thread. maybe i'm dumb.

 

Just use some adequate sized cable, through a grommet in the bulkhead is the normal way, not forgetting to fuse it nearest the battery with correct rating fuse.
To work out current draw if needed use the V/I x R formula, otherwise most likley in the handbook for the amps ?
Welcome to pf btw.

the V/I x R formula = Ohm's law
Heres a link to a calculator if your not to familier with it
