Engine noise after adding amp
Ok this is my first post. I have a 2000 ultra classic. It has the stock radio. First I added new speakers to the front & rear. I went with kicker 6 1/2's in the front & rear. I also added kicker tweeters to the fairing. This made a big sound quality difference but still wanted more volume. So I bought a Elf E2125xn amp. I heard it would fit under the fairing so I install it & get it working great but the fairing wouldn't fit back on. (GRRRR) So I unhook everything and proceed to move the amp to the tour pack. I get everything hooked up & turn it on & the sound is great until I start the motor. Now I have really loud engine noise in the speakers. I've tried moving the ground & shortening it & nothing has helped. Any ideas how to fix this? Thanks, Rob

Also are you using high voltage inputs on the amp, or a converter? If a converter where is it grounded?

I tried the ground wire already. I am using a line output converter. It is not grounded although I know it has a ground wire on it. I'll look at that. I didn't think about the converter. Thanks. I'll update my findings.

if the ground wires on the converter don't work, you're going to need a ground loop isolator that plugs into your RCA jacks. I had the same thing happen to me with one IN THE FAIRING of a 2003 EG. Fortunately I had one laying around.
