Good Evening.... So here is this newbs story...
My Head Unit is a Alpine 134HD
My speakers are Kicker 5 1/4 speakers
My ride is a 1995 Jeep Cherokee XJ 4 Door
The stereo setup like above Headunit and speakers it was nice... But I wanted more. So I installed my amp.
1. Power wire ran on drivers side
2. Constant on drivers side
3. RCA Jacks on Passenger Side
4. Speaker Wire on passenger side
BOOM Engine Whine...
1... First fix attempt. I took each ground off and ground till bare metal. I even ground down the grounds in the engine bay (one from block to firewall, battery negative to wheel well. So I am 110 percent sure all grounds are on bare metal...
2... Then today I ran and bought Brand new shielded RCA jacks. I figured it was the RCA jacks because when I remove them from the head unit the noise is gone.
3... Then the noise was still there so I tried to ground the RCA jacks. NOPE, still there..
So all those above did nothing to improve it.
I want to fix it and not toss a filter on, but I am lost. Everything I know to try has failed me. I have never had this occur before. What is funny, is I took my time. One day ran the power wire and grounds. Did nothing else so I would not be rushed. No kinks, just the right amount of wire, no excess. Then a few days later I run the RCA and Speaker Wires. I forgot to mention I am using new 12 gauge speaker wire too. I just took my time so it would be ideal in hopes I could get the most out of the stuff I had.
So I am open to suggestions...
