Wired directly to the amplifi er: A single 4Ω speaker will present a 4Ω load. A single 8Ω speaker will present a 8Ω load. With speakers wired in parallel: Two 4Ω speakers will present a 2Ω load. Two 8Ω speakers will present a 4Ω load. With speakers wired in parallel: Three 4Ω speakers will present a 1.3Ω load. Three 8Ω speakers will present a 2.7Ω load. Do NOT use different impedance speakers when using multiple subwoofers! JL Audio recommends using subwoofers as part of a bi-amplifi ed system u
