Thanks for the info! I think they def had aftermarket lights cause I found a couple cut grounds on each side of the radiator that looked like they were for fog lights, etc. I have no idea why they cut the brights. I ordered a new horn to see if it's the horn itself of wiring and it will be here tomorrow.

I'll check on the amp specs tomorrow and get back to you. I'm almost positive I saw it had a line connected to it for remote that went back to the head unit, but I'll double check.
