Recently got my coupe and want to re-install my sub out of my hatch. With the hatch i was lucky as it had a car kit in it so it had a hole drilled into engine bay for the power feed. I managed to use this hole for my sub. However the coupe's car kit got its power feed of the stereo's power, so i need to drill a hole for my sub. Which side behind glove box is best to drill from left or right? Can i just leave the hole after it has been drilled or does it need spraying, or a gromit etc?
Secondly i want to amp the front speakers in the near future, so will need a 2nd amp. Is it best to just install a thicker power cable (what awg?) now rather than 2 smaller cables, and then just run it to a block to split? current cable is only small, probably 8awg as it came in a wiring kit.
Sorry for long post, cheers for any help.
