So i have 2 10s behind the seats in my ranger..all my connections are good including my grounds. For some reason though..when my lights are off..so just my daytimes are on..there's a buzzing from my subs..i turn on then lights and it stops. Same with my ebrake. If i put it on no buzzing..but pull it out and the sub buzzes...just like a humming sound. It's annoying! So if anybody has an input it'll be appreciated.

 

check your rca's... may have interferance. also are your rca's and power wire ran together?

 

Definitely check for interference. What you're hearing is probably alternator whine.

Do you hear a change in the tone when you rev the engine?

 

Also check if your properly grounded....I always got exaust vibrations going into my sub cause it wasn't grounded properly.....

 

They're not ran together..should I be checking the RCAs at the amp? Theres no way something could of happened to the ones on the deck..but I can see the ones to the amp getting damaged..I'll check that and see if it works

 

ground your rca's to your hu cage

 

So I checked the rcas and I guess that's the problem since when i unplugged them the buzzing stopped. Although since the rcas were disconnected there wouldn't be any sound..so can i be sure that's the problem?

Also, ive never heard of grounding rcas? And I'm sure all my grounds for the amp and deck and all are fine.

 

strip about 2 inches of wire and wrap it around both of your rca's in kind of a figure 8 pattern and tape it then, find a bolt on your hu cage or any good ground and ground the wire,

come back tell us the noise is gone and be happy :)

 

Even if you bought brand new rcas, sometimes u get really ****y ones. happened to me about 234982139 times lol

 

i have a 93 ranger ext cab with two 10's and two amps in a custom box i made. i just re-did all the wireing for the stereo and no the sub on the pas. side starts pulsing when its on and blew up the driver side sub works fine except i am geting feedback from the breaks and headlights what can i do? i have changed everything three times and nothing is working for me.

 

What about the grounding and isolation of the DTRL… ?

 

the what?

 

DTRL = Day Time Running Lights… maybe I read wrong but bonez stated the buzz was there when the Daylights were on, I assumed (*** thing) he meant the Day Time Running Lights.

 

i dont have day time running light. i grounded the rca's and that fixed part of it but now i am geting feedback from the heater and headlights

 

Is this your thread ? I thought “bonez” said he did ?
