Wiring speakers in series increases the impedance and decreases the voltage per speaker; wiring in parallel does altogether opposite. doubling up the power of a speaker never doubles up the loudness. it means you only have 2x the energy running in now which translates into a 3 db difference i.e. just a meager 23% uproar in sound intensity loudness. Quad cities, il. nov 8, 2011. #2. if you have two component sets for each channel, you simply wire the crossover inputs in parallel. the crossover outputs are normally connected to the woofer tweeter. the amplifier will see both crossovers and thus both speakers in parallel, reducing the impedance load. i did some impedance plots of this exact.
We see speaker wiring in a range of places: guitar combo amps or cabinets, installation audio, pa speakers, car sound systems, studio monitors, and hi fi setups are probably the most common settings. parallel wiring, in particular, tends to be used in speakers with multiple drivers, i.e., pa speakers, studio monitors, and hi fi setups. Step 1: connect the corresponding terminals. to wire a dual subwoofer in parallel, connect the corresponding (same polarity) terminals together in any order. connect the 2 positive terminals. connect the 2 negative terminals. that’s all you need to do to wire a dual subwoofer in parallel. A short summary of my car audio system: · 4 jl coaxials, 50 watts rms per speaker at 4 ohms in all 4 doors. powered by a jl 360 4 amp. powered by a jl 360 4 amp. amp is capable of 70 watts 4 ohm or 90 watts 2 ohm · 2 alpine tweeters in the dash powered by the stock head unit. Plugging in the appropriate numbers, the calculation goes as follows: po = 100 x (4 2) po = 100 x 2. po = 200 watts. as you can see, by upgrading to a 2 ohm stable amplifier and wiring the same four 15 inch woofers in parallel – two per channel – power output jumps fourfold – from 50 watts x 2 to 200 watts x 2.

Safety first – turn off the amplifier: always start by turning off your amplifier to prevent electrical hazards. prepare the speaker wires: measure and cut the speaker wire to the required lengths, considering the distance between your amplifier and speakers. use wire strippers to expose the bare wire at each end. The formula to calculate the total resistance multiple loads wired in parallel is 1 rt = 1 r1 1 r2 1r3 and so on, until you have included all the loads. for our 15 and 20 ohm loads in the example, the math would be: 1 rt = 1 20 1 15, or 1 rt = 0.05 0.06667. this works out to 1 rt = 0.11667 which works out to 8.571 ohms.
