Amp wiring help

I what is the easiest way to get the power cable from the battery and through the firewall? I have an 88 jetta and ive heard there arent readily available holes. Any suggestions would help. thank you.

thanks but a few days ago , i figured out i could use the hole where the hood release cable runs. I just had to widen out the grommet. It worked perfectly.
thanks for the help

A T-splitter would have been smarter so you didnt have to do any structural damage. T split the wires already coming through the fire wall which run 12 V. :licker: D:\Orange Jetta With Body Kit.jpg
