static noise coming from speakers when engine is on

[nickiipoohz]

hey guys, i was driving today and the guy in front of me decided to suddenly step on his brakes. so i stepped hard on my brakes and my speakers started sounding funny. all four (and two tweeters) went wierd. its like a static noise. I checked my ground cable, all my power cables. also checked the remote cable. rewired them as well and its still making that noise. Can any one help me? thanks

WEll you either knocked something out and need to have a look again, or your speaker wires/rcas are running too close to some other wires, and you are experiencing 'noise' (its the actual technical term). Try repositioning your wires so they are nowhere near other wires, especially amp power wires.


Or in braking so hard the rcas might have come loose from the back of ur h/u.

check grounding points

did this happen before you brake hard or just after?

I'd check the speaker connections, both at the speakers and the amp, maybe 1 of the connections is grounding to metal somewhere and causing the noise.

hey guys, okay... i checked the ground wiring and its fine, even changed the ground position just in case, check my speaker wires but nothings touching metal. I redid my remote wire but the sound is still there. what else can be wrong? i unplugged the front and rear speakers at a time too see if any of them are causing the noise but the static noise is still there. any other ideas? :confused:

most noise starts at the source, check out your deck

also you want to list the bands of the equipment???

[nickiipoohz]

ohkiez... got a pioneer headunit, sony 3 way fronts, pioneer rears, jay car tweeters. all hooked up to an alpine v12 amp. tweeters have cross overs. i checked the wiring from the deck but it seems fine. i rewired the cables but still have the static noise. When i have time, im gonna take off the tweeters and cross overs and see if thats the problem. worse comes to worse I have to take everything out and start from scratch. Just want to see all my options before the big dismantling process :D

[ICACHA]

can you try another deck? pioneer's are known to 'sometimes' blow earth tracks in them...

Are the crossovers placed near any 12 volt source? This is a common problem with WRX's when people put their crossovers under the dash. Could be happening to your Honda. :(

[nickiipoohz]

yea... i'll try and remove the cross overs. hopefully that fixes the problem. Cant try another headunit at the time being.. dont have $$$ to grab one lol. i'll keep u boys updated. thanks

[ICACHA]

DON'T remove the crossovers, Marty means MOVE them :)

[DjRob]

are you running amps?

[ICACHA]

even if your not running amps you NEVER run tweeters with out crossovers or at least a cap to cut off the low frequencies or you might as well destroy the tweeters yourself with a hammer :)

Haha, like George said; you don't want to go removing the crossovers all together or else besides removing that annoying sound you'll remove all sound ever coming from that tweeter again. ;)

[nickiipoohz]

ohkiez, i took off the tweeters and crossovers. still there *tears hair out of head", any other suggestions?

[ICACHA]

you know your local stereo shop? :) pay them a visit :)

Usually by the hour.

who in their right mind would run tweeters with no cross over?

if the amp running his speakers has the power cable and rca cables side by side each other can give u engine noise and mayb static noise comming out of your speak.

or mayb its just a wire thats touching something..

i used to just rewire my whole system when i couldnt find the problems but just depends if your upto it
