ShadeTreeMechanic Posted March 18, 2017 Report Share Posted March 18, 2017 Sub leads are short compared to a front to back power run so it might not make that much difference. Normally the CCA would have to be larger than OFC to carry the same current. I use all OFC for everything. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...

Broke_Audio_Addict Posted March 18, 2017 Report Share Posted March 18, 2017 Ofc always. Tinned ofc is even better. That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

audiofanaticz Posted March 19, 2017 Report Share Posted March 19, 2017 Something about subwoofer connections that I always must used OFC, even though I got 20 runs of CCA power wire that is issue free and not corroded like other brands do.

fecupe2001 Posted March 24, 2017 Report Share Posted March 24, 2017 you won't even hear any difference unless you care about a score on the termlab, but some decent cca wires should be enough as long as the runs aren't crazy long I´m the SPL Gains topic creator!! wanna get louder?? check this: SPL Gains.
