what size speaker wire should i use in my car ?

12 GA Transparent
15 GA Transparent Blue?Silver Twisted OFC
16 GA Transparent OFC

hey mate

what are u using it for? how far away from amp/source?

Speaker wire doens't really matter, but for the hell of it i use 12 gauge stinger wire coz it looks nice and good for wank.

Get 12gauge for the hell of it. Doesn't cost that much more. 12 is more than enough for most applications.

amp will be in the boot so it has to run back to the front doors

16 gauge will be fine, but if you really wanted, and doesn't cost too much more, get 12 gauge coz its cool :cool:

16 Gauge is fine, Unless you want to dump about 300W RMS into each door speaker..

only be putting roughly 55wrms to each speaker
