Thumping Noise

Post by Bri94GS »

When i tap my brakes, turn my blinkers on, etc (basically anything that makes a light go on in the back of my car), i can hear it in my subs. I checked the ground a few times, rewired a few times, and got all my equipment tested. Anyone have any clue what's wrong??

Seriously, if ANYONE has ANY noise comming from their speakers other than pure sexually arousing sound, then you need a ground loop isolator. It's not that espensive, maybe $10USD. Go to <A HREF="http://WWW.PartsExpress.COM," TARGET=_blank>WWW.PartsExpress.COM,</A> and search for one. They have GREAT deals on car audio supplies. Hope it helps.

The noise only comes out of the subs...i tried a noise filter, and it eliminated all noise from the subs...i'll give this thing a shot though..thanks

It eliminated all the sound from my subs, including the music.

I heard that putting noise filtors and ground loop isolator is not the best thing for your audio. Aldo it might seem to fix the problem, it only hides it. The best thing is to find the source of the noise and fix it.<P>Ok, now you say that it happens when you tap the brakes or turn the lights on, but is this when the car is on, off or both ?<P>Make sure your power cables run on opposite side of your RCA cables going to the back.<P>Also make sure your battery cables are on tight. It happend to me once when they where a little loose.

None of my wires touch, and all of my connections are tight. It does it whenever the radio's on (whether the car is started or not)
