4 SVC 8Ω subs, wired series-parallel.

How to wire it.

1. 01Split the 4 subs into 2 groups of 2.
2. 02Within each group, wire the 2 subs in series (− of one to + of the next).
3. 03Connect the starting + of each group to a common + point, then to the amplifier's + terminal.
4. 04Connect the ending − of each group to a common − point, then to the amplifier's − terminal.
