Wire gauge for gto 5ez

[kirbybirby]

I have a JBL GTO-5EZ amp and JBL GTO 638 speakers that I'm trying to replace all my factory speakers with. I have 18 gauge wire will that work? Do I need to re-run all the speaker wire (replacing the original wire). My car is not drivable until these are done so any help is appreciated

Stock wiring is fine, im pushing over 100w through some of mine. should be good quality OFC from the factory so i wouldn't worry about it.

most 9 wire that people use to make installs easier is 18 gauge

the subw channel needs 14 gauge or bigger

So 18 gauge is fine for the wires being run from the amp to the speakers?

Yes. Even if the amp is way under-rated and you're running it at 2 ohms -- 18 awg is adequate for 100w rms at 15'.
