If it's an automatic make your own grommet through the clutch pedal cut out. Otherwise there are perfectly suitable grommets on both the driver and passenger side.
I ran my 0awg through the grommet behind the fuse box (passenger side) on my i4 lx coupe, let me know if you have any more questions if you decide to go that route.
I had mine on the alternator but started noticing weird idle issues while playing music but I didn't have any issues before installing my 1500w rms amp. just something to be aware of I guess.im also running straight from the alternator. let me know if i should keep it there or run from the battery?
From the alternator.........
Omg
