Hi there,
i just installed a small system into my ranger but i'm getting horrible engine noise from my sub?! what did i do wrong? i have a 600watt sony xplod amp with a 10" jensen sub and an older kenwood deck. All the wiring is 4g that is fused at the battery. Any suggestions would be great! thanks

 

Sounds like you are getting interfierance from your RCA's and the power wire. How do you have your power wire and RCA's ran? Are they sitting beside each other?

A general rule of thumb is to take your power wire and run it on one side and then run your rca's in the middle of the car or the opposite side that way you won't run into this problem.

What kind of RCA's are you using?

Try seperating the power wire and the rca's and see what happens!

 

i have the power running under neath the cab and the rca's are running on the opposite side in the cab, they are just cheapy rca's from walmart.

 

go buy a nice set of sheilded RCA's and re-run them. The noise will go away

 

things to look at rca's also your -neg see if your - on the amp is good and on the battery

there are more then just that to look at start there

 

You may have ground loop problems. They arise from different components in your system that are grounded at different voltages. Make sure your deck is grounded to the frame and not just through the oem ground wire.

 

are you useing the wire in the rca's for the to power on the amp if so stop that and run a new wire

 

ah ha! that was it!! the deck wasnt grounded to the frame it was only grounded to the oem ground wire! thanks for all the help guys!

 

i redid alot of things befor i got to mine. it was my amp

 

ok that looks better
