Run it to the battery.....test it with a temporary spliced setup first if you want to be sure.

I doesn't seem to matter what source listening to music from. I get the noise when I'm using both mt iPod and my radio. I even get some noise when the radio AND the bike are turned off ( ignition on only)!

Reason I ask is, if you are listening to an ipod or mp3 player and that mp3 player is connected to the charging system, you will get engine noise from it.

I found that it is damn near impossible to eliminate the engine noise so I run my mp3 player not connected to a charger, it runs off its own internal battery. If I need to charge it on the road, I toss it in the tour pack on the charger when I am off the bike.

I have no other engine noise anywhere else, even listening to the radio.
I use 4 gage for the power and ground but I also run 2 amps. So far I have had no issues with noise from the charging system.

If you are getting noice from the amp no matter what source you play from, you can install a Capacitor in between the battery and the amp and that should solve your problem.

Only downside to that is, those capacitors are huge. It is round but probably bigger than the RF amp and you will have to stick in in the tour pack or one of the bags.

rockford tech support told me run it to the battery and that 10 gauge was fine.

Have you checked the ground wire connections on the crimped ends? Maybe it's just a bad wire or connection?
If that all checks out good, then I would look into buying a capacitor like this one....... http://www.sonicelectronix.com/item_...ate-RFC1D.html

Could also be something wrong with the amp, maybe a call to RF tech support is in order?

I had the amp checked out. Luckily everything checked out ok with it. I have a friend that installs aviation electronics tell me that it usually comes down to a grounding issue and to try a heavier better insulated wire. My thought is that with the wire running with all the other wires under the tank that I might be picking up se interference from them.

I ran a 10 ga ground wire with a heavy copper lug under the tank and grounded it to the right rear fuel tank bolt. The positive runs to the battery and is 8 ga Rockford Fosgate wire.

Have been told by several professional installers to never run a amp ground straight to the battery. Using the frame as a ground is the best way to go. The mass of the frame helps dissipate any charging noise.

There is no noise in my radio/amp setup, none.

Check for loose connections and make sure your terminal ends are crimped well. Make sure you are running resistor spark plugs. Non resistor plugs can cause all kinds of noise in the stereo system.

Good luck, I hope you find the problem.

i have the PBR300x2 running at 2ohms with 10g ground & power going directly to the battery, stock deck & the hiddin H-D ant in the fairing. all the speaker wires are routed away or protected from the power & ground wires.
no issues yet, been running it almost a year now.
