I currently have two new rockford fosgate punch 2's and a rocford fosgate power 451s amp to push it. What is the best way to wire the subs? I was told my amp isnt two ohm stable in bridged mode. So I could bridge th amp at 4 ohm or 8 ohms. WHat do you think. I also don't really know what an ohm is and what 4 or 8 or 2 and how it makes a difference. Could someone shed some light on this topic?
