aeroplane sound

[bodybuilder]

Hi everybody my setup got aeroplane sound,quite loud

my kancil ICE i done:
HU : pioneer (used 10months)
front:black mohawk 6" , tweeters
rear:clarion (my fren wira stock giv me)
amp:epsilon 2ch

and i checked ALL the wires,all ok.....

but once i put vol from 0 to 1 on the HU,will sound POP and aeroplane sound will come,if i put vol on HU to 0,will be silent no aeroplane sound

then i tested on discman to amp(rca) no problem....with HU vol=0

whats the prob guys......is it grounding or my HU kong?or somekinda wirerings behind HU??i saw a lot of wires on HU....but i dont understand at all

 

[craziechild]

you bolt the ground to where?

try to use a wire directly from your battery -ve terminal to your amp... it worked for me...

Try this step to determine where the pop comes from

Remove the RCA from the amp, and on the HU. If still got pop, means your amp, if no pop means from the RCA from the HU to amp is the problem. Most probably I would say its the amp.

hi
So U already test ur system with another HU, i mean discman, so no problem.. i think the problem coming from ur HU, also check ur amp vol level, if u wanna check it, please turn ur amp volume below half level, then try turn on ur system again, make sure ur ground cable HU connect directly to the body or to the battery. Another test is turn off ur engine and turn on ur system on, what will happen? will u hear the aeroplane sound again? This thing can be done if u take some little time to setup ur system correctly dont be rush and be carefull...

First of all, when you install your ICE? I mean are you install your ICE seperately. Install HU first, then after sometime only install amp and speakers. Maybe the remote they never connect from HU to amp, or maybe have problem with your HU, try to change the HU or connect RCA cable from your friends car to your amp(need another length of RCA cable) then try again.

i also got the pop prob same as u before..but it already resolved....wat i do is i connect the remote wire for AMP to acc wire...same as the HU..before this i connect the wire to remote wire from HU...

Pre-amp you can get from Lelong, but I not that recommend you to buy, cheap one normally will give you airplane sound.

Why do you still need 2 RCA cables as you have 1 already? For this price is hard to get a good 1. Last time Lelong got sell, now no more liao.

How thick the power they give you? What is your amp rating?

 

[bodybuilder]

audio quart is rm230 the preamp....quite pricy

because 1 is from HU-preamp and 2 more RCA from preamp to amp(4ch)

duno...jus he said thick 1...not cheap type...,amp rating85w x 4 RMS

 

[kyheng]

I send you a PM already.

 

[howiechoo]

is the problem solve? if not then pm me..

I have the same problem as well. Previously is OK, after testing 3 way electronic crossover in my car. Found it doesn't suits my audio, so I put everything in orginal position. Then the aeroplane sound started.

I've tried all the method and ideas given by sifu. In the end, I unplugged the RCA connectors behind my HU. Aeroplane sound disappeared. So that means I have to change a new RCA cable? I really scared that after changing a new RCA cable, the same problem still there. :(
