Leaving 2 speakers in parallel across 2 channels will potentially damage your amplifier, especially if the voltage is dropping below 12v. The Amp is 4 ohm stable bridged, not 2 ohm. See my first post. Rewire to a stable load and if you can use an oscilloscope to tune the gain for a clean signal.
...Also it install a system volt meter to monitgor the voltage levels so I can make sure I am adequately charging the system?
I think it is essential to have a voltage monitor, again, that system is capable of using about 450W and you only have about 120W. On the X I had the Kuryakyn linked above but in chrome, comes with sticky foam on the bottom and mounted it on top of the triple tree next to the left riser. On my GS I went with a sparkbright multicolor single LED. I like the sparkbright better as I only need to see one light. Not sure if the sparkbright would mount under the tank console on the X. I think every bike should have a monitor, bike's electrical systems are probably the most prone area to failure. Good to know about a developing problem before it becomes a showstopper.
