Help with wiring 4 PIAA horns
2011 JKU. She's lifted and mean looking and the pipsqueak stock horn just doesn't suit her. I don't want to go the air horn route, just something a bit more ballsy. After much research, I've decided to go with the PIAA 85115 Superior Bass Horns, 4 of them to be exact. According to the description, the horns draw 2.7 amps each, for a total of 10.8 amps for all 4 that I want to install. I assume installing a relay is the way to go but do not know if the stock wire harness is sufficient for 10.8 amp draw. Anyone know how I can wire this, what parts I would need?

Most of the 12v wire gauge charts say 10 amps can be handled by 16 or even 18 gauge if the distance is under 10 feet. That said, I would install my own relay and use the current harness as the trigger for the relay. Wire the relay as such:
87 - power to your new horns
85 - ground
86 - signal - this should be a POSITIVE from your current horn harness
30 - positive from your battery
