Depends on how much power. I used the factory 14 gauge in my 16 focus but 3 runs of 12 gauge in my 10 focus since I was running a 3k monoblock on my front doors.
Is it 12-14 the common spec for a driver or tweeter powered by a typical four channel amp. An exception is scenarios like Popwarhomie. 3k on a door sounds outright rad.
Not concerned about the wire itself just wondering if it sounds better to connect directly to the amp or if using the preexisting wire will work just as well as some new ofc
I'd like to go with a bigger amp but im not buying an alternator
