So my truck got broken into last night, stole my dual 12" type-rs zx750 zx350.4 and my diamond audio D6 components. Real nice thing to wake up to (n) so the type-rs were nice but i think im gon for a single 12", i already got an Alpine MRP450 (4oo WRMS @ 2ohm) and i was wondering which will have the greater SPL. A 12" alpine type-R or a 12" kicker comp vr, this is only off 400W rms so the type-r wont have enough power to truly shine
