I'm about to buy a kicker 11dx250.1. 2 ohm rms = 250w, 4 ohm rms = 140w and was wondering if the kicker comp 10 2 ohm sub would be louder than the 4 ohm version. Just want to add a little more kick pedal from rock music. I'm basically a noob when it comes to car audio so any answers are good answers! Thanks in advance!
