I'm in a debate to sell my (2) 12.4 Orion hcca's for a new set of subs. I'm looking at IA death penalty 12's right now. I've never heard them In person but I've never heard a bad thing about IA. My goal is to get loud on daily music. Are the DP's musical at all? Will a pair be able to handle 4k daily? My vehicle is a 2001 caddy eldorado. Amp is MTX te4001D just a lil over 4k @ 1 ohm.
