[QUOTE="zman, post: 117994, member: 2904"] First thing to do is find out how many ohms your speakers are that are on the bike now. I do not believe the diagram will tell you that information but it should be stamped on the speaker on your bike, or you could look at ebay pictures and see if there is a close up of one for sale, chances are they are 4 ohm..Also you can remove your speakers and test them with an ohm meter by touching each terminal with the the probes, doesn't matter which probe to which terminal for an ohm reading. I am 95 percent sure they are going to be 4 ohm, they will read anywhere between 4-6 ohms. So now we know your amp is set up for 4 ohms. This setting cannot be changed on the amp so to realize 4 speakers without sacrificing volume or sound quality we need to turn 4 speakers into a 4 ohm load for the amplifier. To do this you need to buy 4 speakers that are 8 ohms each and run a parallel wiring to them just as explained in the first part of that video. Thats all you need to do and the sound will be the same except more of it from the rear. Remember the amps ohm rating cannot be changed and with only one left and one right channel the only way to accomplish 4 speakers is by parallel wiring. [/QUOTE]
