Hello... i am looking to get a Denali sound bomb as well... just worried that battery is around 9amps and the horn draws 20amp. how does that work ? does the engine needs to be running ? or can battery withstand the current draw?
The figure you're looking at is the capacity of the battery. Batteries can output much more current than the AH rating. The relay is what makes everything work. The stock working cannot handle the current so a working harness with a relay is required.
