I never put a meter on it to check. Could look into it next week when I get back to my multimeter.
I'm running both a kicker ZR360 and ZR1000 on a 60A fuse. Haven't blown it yet with the horn, went thru 2 with the direct radiators.
My convertible has 1/0 and a 150a fuse to an XS100, ZR240 and ZR360. It fried the factory alternator, so i had it rebuilt and it benched 158a. I run a pair of JL10w3v3s and there is not enough bass, especially with the top down. Not big enough for a horn. I was going to use my pair of solo-baric 15s but they need some fiber work to do it right. I'd consider a TC Sounds 18 in the spare tire well, but they are ^^$$.
To me the THT sounds the best of the many combos of subs I have had in the Explorer. Of 6 12"s, 4 13"s, 4 15"s in the truck, I'd take the single 15 THT over them any day.
With the THT the 35hz fundamental in Decibel is so clean, none of the Direct radiators had such a pure tonal quality at high SPL. I can park outside of bars and rattle things on the shelves inside with this thing. lol
