It's time to upgrade. I have sold my Orion HCCA 12's. Now, I need a sub or several subs that will work with my modded MMATS D300HC amp. So, I need the final load to be 2-ohms. I want to increase my SPL while still maintaining SQ. Tell me what ya'll think - 2 Kicker SoloBaric 15L7's sealed, 4 Kicker SoloBaric 10L7's sealed, 1 JL Audio 13W7 slot ported, 2 JL Audio 12W7's sealed, 2 Orion H2 12's slot ported (whenever available), or does anyone have suggestions? I have considered Resonant Engineering RC or XXX subs and Beyond Audio Inhuman subs but am unsure if I will be able to get a 2-ohm load or close to it. Please let me know what ya'll suggest.
