Good evening. So I have the Cerwin Vega b54 amp with the BT Line Leveler for the front two Infinity Kappa speakers. I want to add speakers to the new lids in the back. I assume i need another line leveler. Do i also need a breakout connector. Not sure other than speaker wire, speakers, and obviously connectors what more I need? Infinity Kappas are 2 ohm. Should i stay with a 2 ohm rears or does it matter? Any advice would be great. Ty.
