I have a (1001 bd rf mono amp 1000 watt going to) rockford fosgate p2d2-12 dual 2 ohm wired at 4 ohms in a box. From there connected to a box with an old school 12 in Earthquake Tremor (single 8 ohm) and from that box to a Rockford Punch HX2 (1000 watt) dual 4 ohm sub wired at 8 ohms and somehow my amp is pushing at 2 ohm, 1000+ watts... Can someone explain to me how this is possible? Thank you very much.
