Audio/Firewall questions.

XtreeX · 10-08-2006, 06:20 PM

Guys I have been looking for the past 24 hours on every supra forum and search possible but i cant find an answer. I need to get through the firewall of an 87' Turbo 5-speed mk3. I've checked and its very cluttered on the drivers side with different components and its very hard to get underneath because of the clutch. I did it perfectly fine on my 90' n/a auto mk3 but I am stuck here. Please help!

And if i need to drill where do i drill? Pics welcomed!

Anyone else have any other ideas or more detail on doing this?

I need to drill a hole or find a hole for my amplifier's power cable, and I cant find ANY breathing room. And its always a bad idea to start drilling blindly

do it close to the clutch's master cylinder
there's enuff space there to put wires thru for ur amp

what gauge wires are u planning to use

i put my power wire through a hole already in the firewall near near the master cylinder. inside it comes in back above the pedals. idk if everyone has that hole or if it was made by a previous owner of my car.

you can also feed it through with the speedometer cable just have to poke a hole through the boot

The speedo cable hole/boot/gromet was what I was going to suggest. The whole itself is plenty big for more cable. You may be able to squeeze your power cable along side the speedo cable current hole in the boot/gromet. If you can avoid taking that boot/gromet out do it...real pain in the butt to get back in properly. I would also feed your power wire (tape about a 3 inch stiff something to poke through)...feed from the outside (engine bay) in...then contort your body like some yoga dude under the dash and pedals, find it and pull. Good luck.

I had to run an 8 Gauge and a 4 Gauge so I ended up just picking up a metal drill bit and lettin it ride! I can't remember now cus this thread is actually kinda old, but I believe it was right under brake booster (or right around there)

Thanks for the help guys, Im just having the problem of not knowing where exactly to run the cable through from the engine bay? the thing is the cable is already run from the back of my car, so it would be going OUT through TO the engine bay, Anyone have any pictures or a REALLY detailed description? GREATLY appreciated!!!

This is where i drilled. You can see where it came out in the engine bay. It's 4 gauge wire going from my battery to my trunk.
