Compressor has to be within 17” of horn? So no roof mount?

2015 Silverado Lt. I have 6 individual trumpets in between the grill and the radiator. They are mounted around the edge of the radiator not to block air flow for cooling. 4 compressors are mounted in the front of engine compartment, two of the trumpet lines are 4'FOOT, and then the rest are at 3FOOT. They sound great and are LOUD! 4' would get you from the cowl in engine compartment up the windshiel/door piller to one side or other between roof liner and roof. You can test out the trumpet hose lenght before you do all that work. All together 6ct in my truck are VERY LOUD!!! Trains though still out do me but not by much .LOL signed, Huh?

Whats the warranty on this, my horn has stopped working?

You probably need a new relay. That's what I am replacing on mine right now. They go out over time. Its a JD1912 12V 80A relay. Here is one on amazon: https://www.amazon.com/gp/product/B07W6Y7811/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1

I bought two kits. What’s the best way to hook two of these up? Also has anyone used one compressor with air hose ran to two horns?

Just splice the horn wires into both. Compressor won't run both optimal. I ended up keeping stock horn on truck since when I lock my truck, the horn wasn't honking ( lock feedback) as if the compressor wasn't able to do it.
