SPEAKER IMPEDANCE MATCHING & HOOK-UP GUIDE: (Continued)PARALLEL: When wiring in parallel, the resistance of the speakers decreases. Two 8 ohm speakers wired in (hooked-up) Parallelresults in a 4 ohm load. It’s easy to calculate the effect of a resistive load when all the speakers are all the same resistance. It is reallynot suggested to wire different resistive load values in Parallel (8 and 4, 16 and 8 etc.) The formula for figuring the total impedance inParallel is the multiplication of the two loads divided by the sum of the two loads - i.e. putting two 8 ohm speakers in Parallel resultsin a 4 ohm load. Connect the Positive side of Speaker A to the Positive side of Speaker B - Connect the Negative side of SpeakerA to the Negative side of Speaker B.Speaker A8 OhmsSpeaker B8 OhmsBLACK SHADOWBLACK SHADOWTotal Load = 4 OhmsNEGATIVEPOSITIVECOMBINATION OF SERIES & PARALLEL: This is really just two sets of Parallel wired speakers connected in series. This is howyou maintain a consistent load with multiple speakers. The importance of this is more evident when you have more than one cabinetto connect to your amplifier. This is when you need to figureAll 4 Spkrs. are 8 Ohmsout the loads and how to wire them up without applying toolow of a resistance on the amplifier.SPEAKER ASPEAKER BSimply connect the Positive side of Speaker A to the Positiveside of Speaker C.BLACK SHADOWBLACK SHADOWConnect the Negative side of Speaker A to the Positive sideof Speaker B.
