Need help getting through firewall please!

[Multimaster]

I for the last two weeks I have been installing an AM sound system, the last thing I have left to do is run my power wire for my amps through the firewall but am having trouble.

Are there any existing holes I can look for in a 1994 Grand Prix or do I have to drill?

Usually there's a big grommet for the antenna...if you have the dash apart you should be able to trace it. I think it's over above the pasenger kick panel

passanger side by the heater box (sorry brain fart for technical term at this time)

for the 1997-2003 series there will be 2 places ones a little closer to the battery but ALOT harder to work with.

for the close one. on the passenger side floor board up close to the dash pull the carpeting back. right next to or close to the center counsel there will be a gromet. that ones packed full of wires and hard to fit anything bigger then a 8ga through. i tried running a 2ga wire through this one and fried out my HUD system on my last GTP

the other one will be located right below the master cylinder. you go inside under the dash up behind the brake pedal take a flash light and look up there and you will see it. if you take a hanger you could fish it through this is where i ran my 2ga wire. its easier if you have someone helping you. and easier to go from inside the car fishing it out toward the engine bay.

as far as the 94...im not quite sure sorry.
