That's aeroplane sound la... Need to troubleshoot, a lot of things can cause aeroplane sound.

Stuff like: battery going to be dead soon, power cables too close to RCA cables(this one implies to cheaper cables without shielding), grounding not enough for amp, grounding at HU pre-out got problem.

Aeroplan coz by unproper grounding wiring solder or lose connection... check all your ground cable.. HU, pre-amp, e/ross & amp...

 

[ekud6881]

mine sound like that too.. waa.. how much to check all that?

 

[oldskolboyz]

Do it your self laaa... very simple 1... pre-amp, E/cross always give aeroplan 1... just check the ground cable (see at GRD terminal)... rewire it back & add 2 or 3 additional ground for that stuff loorr... If the aeroplan still around after rewire the ground cable.. time to change your cap ayam RCA cable loorr...

If sound like plak..plak came out when on/off HU or change track than you need to check your Amp grounding cable.. as I know laa.. aeroplan sound nothing to do with amp grounding cable...

You can actually try a muting plug if you want to ascertain whether it's your amp the culprit for the aeroplane sound. A muting plug is a RCA wif ground sorted to the signal.

Anyway, if you want to save the hassle, most shops charge about RM30 to check the problems for you. Happy ICEing :_:

Or maybe u can ask something like "NOISE CUTTER" at accessory shops .. shud be arnd RM20 - RM30 depends on brand. or go to halfcut shop and get from some jap's radio down there and DIY :)

As I said earlier add 2 or 3 more wire for grounding lorr.. even I use Macrom 48.13 (collector item,cost me RM980).. I put 3 wire for grounding..... go to Jln Pasar/Pasar Road buy 10awg cable (Black) around 1 meter.. cost around RM1.20 per meter... cut it around 1 feet.. than you can get 3 set.. so connect it loorr.. by the way for RM1.20 not cheap either, if you go by car.. need to spend around RM10 for parking... better use motorbike...

For me Noise Cutter 'NOT THE SOLUTION' & the most stupid idea I've been heard... very costly in the future.. sometime can damage others equipment in long time use... as we know Noise due to unproper wiring in your system.. so U need to rewire it back.. that the only SOLUTION... even Branded cap ayam system, noise or aeroplane will gone after rewire back the grounding...

best way is to go back to ur installer la.....

very small zzzzzz sound is normally gain setting too high becos of Hu player not clean enaugh,

run with engine you need to check the power cable and rca cable run-way. and also the rca not tighten enaugh

 

[Zenn]

could be a number of things, lets start with the most probable.

does the noise come from both tweeters or just one side? maybe the speaker wire or the passive crossover is too close to the power cable.

if not, turn the RCA signal wires around (from HU to amp) and see if the sound switch sides, then u know its not speaker wire problem.

u can check the amp gain if its too high, just lower it a bit and see if the noise dissapears when u rev.

may also be rca wire doesnt have good grounding inside or in the plug. borrow a spare rca and replace just for testing.

also can try adding extra grounding wires to the amp or even the HU to see if bad grounding is the culprit. make sure u grind the paint off (to bare metal) before u apply the ground wire to the chassis (via screw or solder)
