Power Wire for subs

[Wolfblitz]

Trying to find the best way to run a 4 guage power wire for 99 firebird. Need it to go through the firewall, but cant find a hole for it. Any ideas?

Drill?

[deadtrend1]

yea, there arent any holes really. Aside from using the hole behind the PCM on the passenger side, but a 4 gauge isn't going to fit without a new hole and grommet.

Got mad, took a drill to it. Fuel pump decided to take a crap on me tonight though

i always run my stereo wire behind the pcm through the large grommet there, its 4 gauge too. granted it was never on an ls1 but i would think you could get it through there.

His car is 3.8 liters of fury. But the hole behind the pcm on ls1 cars is big enough to run the wire. I have my 0 ga. wire running through it along with everything else.

Nothing wrong with 3.8 fury, especially when u spray it lol. Subs are in btw, thanks for the hole ideas
