A:AnswerI would cut the gain down a bit for the woofer. I don't know how many channels your amp has, but concerning the woofer...cut the gain down a teensy bit to play it safe. I don't know how loud you want your system to be, but i would hook the 6.5" speakers to the head unit. I'm assuming you have an aftermarket unit. Cut the bass down on the head unit also. Most head inits supply enough full range watts to keep up with a 400 watt amp or less. Just my humble opinion.
A:AnswerI used a line out converter in my 2015 terrain i have 2 of these subs on a 1000 watt memphis amp i suggest going with an amp around 5-600 rms it will sound really nice and i also recomend a ported box
A:AnswerThe sub will work without an amp, but the sound quality will be terrible at best. Just get a small amp for the sub. Make sure it has a built in crossover or add an active crossover.
