hi, my amp got high pitch sound.. my friend call that aeroplane sound? when i accelerate more, the pitch sound getting stronger.. what happen?

i think its called alternator Whine... i had the same problem after installing my amp... but was able to eliminate after add a device at Head unit...

The noise doesnt increase as the head unit's volume increase.. it increases when my RPM increases.

there are several causes of the noise.. but most common causes are usually inproper grounding or Head Unit problem... mine was cause by head unit.

yap, exactly like what u stated.. how much u did n where?

u can just go to any ICE shop.. they can do it... i went to the shop that installed my Head unit... at 1st they told me my Amp got problem.. because i DIY installed my amp.. then i ask them to check with their amp.. still got same problem.. then after they check the headunit.. add a Hi-Lo converter.. problem solve... they say my head unit RCA out got problem..

why not check your wire route first
what HU you using?

changing from RCA output to Hi-Lo is not a good solution
there must be something wrong with ur HU

TS,
need to check 1 by 1
why not go back and ask ur installer?

how am i supposed to check when i have nil knowledge on those wiring stuff in ICE
i'm using Pioneer low end model which i forgotten what model

herm, my installer is howiechoo n when i sms to him, he said he is bz with exam or something like that.. then he ask me to find other ICE-installer so i'm asking which place is reasonable n cheap XD
my location Seri Petaling, KL

if i were you
i'll bising him to check for me for free
it suppose to be a service which the installer provide

that's why
there's difference between shop installer and free lance installer
although more expensive but u can get better after sales service

howie charging me rm100 for everything.. my friend go shop around rm280 including wiring everything like what howie did.. so where u wana go?

u shud have post it up and ask
i install my stuff

2 baffle ring, rear amp board 2 pcs mdf, 4awg cable from engine to rear, RCA, speaker cable

rm200 settle

they even repair my HU for free cos my HU got the problem wit the RCA...

hmm, of coz, i would not ask u to check for free
dont worry
coz u r 'trusted' edi in my mind, so i think better let u check lo coz other mech might tell me this n that rosak although it wasnt that part faulty.. btw, i'm still waiting for ur sms

i think;-
1) u didnt do ur grounding properly, loose grounding also will create aeroplane sound.
2) or ur rca cables running parallel together with power cables
3) battery weak n faulty alternator also can lead to aeroplane sound

1st 2 question need to ask howie liao.. but for 3rd question, the battery is newly changed GP MF 70
alternator i dunno rosak or not but my car is working till now since the sound is heard (i think month ago)

i will find 1 day to check for u......inform u later....

ok.. sorry for the fuss

No worries, there r lotsa culprits which can lead to aeroplane sound, even experience installer also facing this kinda problems. If installation no problem then most probably either amp, hu or crossover.

Bro, altho ur alternator still charging n working, its doesnt mean that it wont create aeroplane sound, some install helix alternator cap to overcome it.
