[QUOTE="NSTALN, post: 8272454, member: 588169"] Series/parallel the coils: (1st pair of coils) 1.5ohm & 1.5ohm parallel = .75ohms (2nd pair of coils) 1.5ohm & 1.5ohm parallel = .75ohms Run the two .75ohm pairs in series: .75ohm + .75ohm = 1.5ohms. Also the coil readings when static will be lower than the readings when the coil is passing current, the heat will cause the impedance to rise by roughly 30%...so 1.5ohm(static dcr) x 1.30% = 1.95ohms nominal impedance(roughly). Any quality 2ohm stable amp should be fine with it. I used to own a TC3k quad 1.2 ohm coil and wired it the same way. [/QUOTE]
