Hella Horns? Who loves what?

So, I got the relay system hooked up all credit to @bagleboy and my crayon
Pictures…

HOWEVER, exact same readings on the DB meter app as when I used the factory wiring with no relay.

40 amp relay, with a 30 amp fuse. All 14g wire.

any thoughts?

 

Db is a logarithmic scale so it’s difficult to measure small gains. I promote wiring upgrades on general principle whenever a mod looks to approach wire capacity regardless of other benefits. From what I could find each horn might draw ~7A so 4 would be 28A. That seems excessive for the stock harness. I think they sustain output better now but that’s a butt dyno measurement and we all know what those are worth.
