View Full Version : what gauge for amp to door speakers

02-22-2009, 10:44 PM
is some cheap brand 18 gauge okay for a ~15 foot run from the amp to the crossovers? And then for the crossovers to the tweeters and woofers?

I have a ton of 18 gauge speaker wire(2 runs connected to each other) and I have 50 feet of 14 gauge power wire (just one run of wire).

Is it a good idea to run the 18 gauge from my amp to the x-overs and the 14 gauge from the x-overs to the tweeters/woofers?

depends on how much power. I have 16 gauge ran to my quarts with 85 watts.

why not run the 14 ga from the amp to the crossover

and then the 18 to the mid and tweet?

realisitcally you wont notice a diffrance in sound

mostly because I would need two runs of the 14 gauge per side, it is like power wire.

I think I will just run the crap off-brand 18 gauge to the x-overs, then use the 14 gauge from there to the woofs/tweets.
I just wanted to make sure that 18 gauge over the length of the car wont be a problem.

i don't run anything less than 16ga. personally, but i doubt you'll notice the diff between 16g and 18ga.
