Guys,
I have a quick question. I removed my stock door subs and I'm installing new JL subs. I have a question on the wiring polarity. The connector has a solid black wire and a black wire with green srtipe. Which one is + and which one is negative? The black with green stripe wire has a slightly larger connector so I wanted to assume that's the +.

Any insight is a help.
