Parallel Parallel wiring two speakers together is done to reduce the load (resistance) the amplifier sees. This is accomplished by connecting the positive terminals of two speakers and the negative terminals of those same two speakers to a single channel on the amplifier as seen below. So two 8 ohm speakers become a 4 ohm load, two 4 ohm speakers become a 2 ohm load.

It appears that way because it's only showing one side! So another two speakers would hook up to the left side! Hope that made sense

Makes perfect sense, but what if you have a 4 channel amp rated at 2 ohms, and 4, 4 ohm speakers. Would you bridge channels 1 and 2 for your front speakers and then bridge channels 3 and 4 for you rear set? Or, would you buy the same amp in a 2 channel version and hook up your front set to channel 1 and the rear set to channel 2. I would think you would want the 4 channel amp to take advantage of the higher power rating capabilities, but I could be wrong. Thanks for the response!

wiring Amps. and speakers on a 2006 FLHTCUI
I have a 4 chan. 4 ohm amp. and Harley Boom speakers that are 2 ohms. Does any one know if I wire the front speakers in series from both front channels, and the same for the back speakers from the back channels will it work and not loss any volume which happens with normal series wiring. P.S. Amp. is not bridgeable.

2017 Ultra Classic w/ M8: Stage II Boom upgrade Question. Replacing/upgrading both the fairing and the tour pack speakers and also adding the two amps. All HD kit. I believe that I still have to flash the system.
My question is... can I flash system myself? How? ... or is this best left for the dealer?
