loud scream from all speakers!

[Mr Bojangles 10+ year member]

Help I just hooked up a 4 channel in the titan and i've got a loud scream like it's a problem with the rca's but I bought high end wiring so this would not happen! I know you can buy something that wires in to reduce noise but i don't think something like that will work in this case.. I can hear engine noise, cd spinning, and all other noises.. Anyone had this trouble before?

if you unplug the rca's does the noise go away?

ground loop, buddy

yea

if you have an ipod or portable mp3 player, etc, hook it to your amp and see if the screaming continues, if so I would say your amp is boned.

If it doesn't hook your ipod to your rca's up front and test it.

basically isolate and test up the chain to see whats fukd up

I figured it had to do something with a ground. So you mean i'm getting a ground on the power somewhere?

Yea that sounds very similar.. Where do I start at troubleshooting in a situation like this?

 

[jmanpc 5,000+ posts]

yeah. that ground loop is exceedingly homosexual

 

[Mr Bojangles 10+ year member]

Does that mean I don't have a very good ground, or my ground is bleeding over the rca's or the ground is bleeding over the power?

start at the back of the head unit. make sure you have a secure ground for it. keep your RCAs from power wires (I can move my RCAs 6 sinces and hear an increase in noise... so the people who say that its not the RCAs by power wires are wrong.) make sure your amp has a secure ground. are you, by chance, using a pioneer hu?
