I get Alternator noise with RPM's. If I use this Ground Loop Isolator will that help or eliminate the noise? Thanks

 

it will help, but I've found some also filter out low end frequencies. You are better off finding the issue vs. treating the symptom.

 

I have had this same system now going on the third year. About a week ago I started getting the whine with the RPM's. If the bike is not running it is crystal clear. While running it is still good but I can hear the whine. I have Biketronics Titans in front 6.5. 6.75 kickers in the rear. With Kenwood X998 and Power Acoustik A3000DB • 3000W Max Class D amp. Power and ground run from the battery to the AMP. Clean heavy lines. Same with the speaker line. I got my install advice from Haze and Gannicus. Why it worked for two years and now makes noise I am unclear. Only electrical add on was engine guard lights. LED. The power is pulled from the cig lighter which is where the amp trigger is but that should make no difference and it worked fine for 6 months. Any suggestions I am all ears. Thanks

 

Disconnect your leds and see if the problem persists.

 

I bought an Isolator and two sets of high end 1 foot RCA cables. I hooked up everything and it was perfect. After wondering what frequencies I might loose from the isolator. I took it out and it still sounded perfect. I am guessing my cables were bad. Well I have an extra part but worth it. I am just glad it was so simple. Thanks for all the advice and comments.

 

That was an easy fix!!! Yep, sometimes a better RCA is all you need. Can't say that's never happend to me.

 

I want to remove static from the speakers on my '99 Ultra. The bike uses a wiring harness for power and speaker connections. There are no RCA connectors. Any suggestions where I should connect a ground loop isolator?

 

 

Didn't change anything. Static was coming from the speakers when I bought the bike. Got it from an auction, so I don't know the history.
