Where to ground amp and run power wires?
Hi all,
I have done wiring for my old 98 corolla and 05 Matrix but I'm stumped as to where to ground my amp in the trunk. I don't see any readily available bolts on the body. Suggestions?
Where did you put your ground wire in the trunk? I always use a wire brush attachment on a drill to remove the paint for proper ground so it has to be easily accessible for a drill.
Also I was thinking about running my 4ga. power wire through the grommet but that is soo high and hard to reach. I was thinking about drilling through the firewall and putting a grommet. You think there is enough room in that factory grommet on the driver's side for a 4ga. wire?
Drilling the firewall easier? I'll post my setup once it's done.
I look forward to your responses and thanks in advance.

All the locations you've tried use "rated hardware" ( usually grade 8 ), and while they're stronger than normal screws, they contain a high concentration of zinc, which isn't a very good conductor. Car manufacturers often use Loctite in these locations that would further reduce conductivity.
Again - find the frame. Sand it down. Stainless steel screws FTW.

Thanks tC peeps. I'm also looking at Mandos's "How to gut a tC. https://www.scionlife.com/forums/viewtopic.php?t=60981
Hard to force the 4ga. wire though the gromet on the driver's side? I'm planning on forcing it out to the engine cabin from the inside cabin.
