Wiring problem, rear speaker, 98 t/a
Your Alpines are single voice coil which means you will only be able to use 1 coil or 1 pair of the 2 wires resulting in a -2db loss in output...not a huge loss. The only problem is that the Alpines are not capable of sub bass frequencies.
I am assuming also that these are not coaxials and are some kind of a component set. Coaxials (tweeter mounted in the center) will really not work in that location as the sail panels are strictly bass only from that location dictated by the Monsoon amp that powers everything.
