Question:

How do you run the amp power cable through the firewall in a 1994 Mitsu Eclipse?

I've got a 1994 Mitsubishi Eclipse GS 1.8 and I can't find any place to put the amp cable through the firewall! Any tips would be greatly appreciated. Thanks ;).

Answer:

Just adding to the grommet guys answer above: Just as important as the grommet; a fuse. You must have a fuse as close to the positive battery terminal as possible. Why?, you say? If, for whatever reason your power wire shorts out to the frame somewhere between your battery and your amp, what's going to prevent that wire from turning into a giant heating coil running the length of your car, and torching it. I've seen it first hand many times. And, no, the fuse at the amplifier, the fuse in the distribution block (if you're using one) or any other fuse other than a fuse at the battery won't do a thing for you power wire unless it's before the potential short. Like at the batttery... In short, the grommet prevents the short at the firewall. The fuse protects it in case it does it anyway.
very nicely so what you desire to do it pull your carpet back a sprint. you need to locate a rubber groment. (additionally in case you persist with wires you will locate the place one is. my motor vehicle the groments have been to tightly packed to in advantageous condition 4 gauge twine by so i drilled a hollow with a drill observed piece kit) and fastened a groment that i picked up at my interior reach oReily autoparts keep into place and ran the twine by. labored great! only confirm you do no longer DRILL INTO something!
If your car is an automatic, you can go through the plug that seals the hole where the clutch would be. If you have a clutch, you will need to drill a hole in the firewall if there are no other available plugs.
It's simple really. If you have a drill will a power cord attached to it, simply drill a hole big enough for the power wire to fit thru. Try to do it about midway down the firwall as to not hit anything in your dash. Thats where I have done it before and have had no problems whatsoever out of it.
One very important thing people forgot to mention. Be sure you put a grommet in the hole you drill so the power wire doesn't get cut by the sharp edge and cause a short. You'll have to take into account the size of the fiitng of the grommet to ensure a good fit.
