    Well, you are right in some point, but if you can get a real good one that cost rm1000 for 1 meter RCA cable, then you can feel the difference. I have 1 Lightning Audio RCA cable, the sound quality that comes out from it is same like my rm50 RCA cable.

    WAH all the gurus here max. brain storm liao...

    IMHO:

    1. Unplug RCA from your 2 channel amp (subwoofer). make sure you balut the RCA head with wire tape, do not short-circuit them.

    2. Unplug rear RCA from your 4 channel amp. Also balut them.

    3. Unplug the balance RCA for front channel from the 4 channel amp, now swap left to right, right to left. Check whether the aeroplane FLYING to front right :D. If yes, you got the answer lor, HU got to go. If aeroplane still flying on the front left let me know.

    Good luck.

    Honestly speaking, did you or did you not short-circuit your system recently?

    What brand and model of HU your are running currently?

    How does this AEROPLANE started to FLY on the front left channel?

    pioneer 3750

    i oso dunno

    now the aeroplane sound oredi decreased due to the audio isolator that i install couple of days ago......then my fren that installed the whole set of my ICE system try 2 seek for the aeroplane sound cause.......he try to lower the preamp volume n press my ofuel pedal,the aroplane sound sound dissapear......but i have 2 up my volume on my HU 2 60suntin to enjoy my sound system!

    now he adjust the preamp volume lower than half.....so that i can enjoy my sound system by increasing the HU volume to 36!

    hehehehehehe,thats all sifu........

    now the aeroplane sound has gone!:shades_smile:

    alan86,

    throw away the pre-amp <-- hopeless item for current trend. Save some money for built-in X-over HPF & LPF HU. Try bypassing the pre-amp and see whether the radio frequency sound still appear. Im afraid your HU too old, more than 5 yrs?

    Hiya... why don't you get 5-series or 6-series... with built in X-over.

    DEH-3850MP + Pre-Amp = DEH-5xxxMP / DEH-6xxxMP

    Less wiring = less noise & power drop / less resistance when transmitting signal or power.

    Happy working & ICE

    Looks like your pre-amp and amp got some problem, where pre-amp cannot give you clean signal when turn to high volume which this is normal for a pre-amp(assume your pre-amp is ayam brand), amp is maybe earthing no good I hope, then you will have less headache. If not then your RCA cables also need to check already.
    Even if your HU gives the airplane sound, you still can use the high low converter to solve the problem. Have check your HU, it don't have built in crossover. This is the down part, you still need a pre-amp or e-crossover

    Promise me you are not going to just buy the x-over after reading my xplanation below :D

    Before that, trouble from square one. Apply the basic rule first:

    Ayam HU -> Good Pre-Amp -> Good Amp -> Good CS -> Ayam SQ

    Good HU -> Ayam amp -> ayam CS -> moderate / maybe good SQ

    Head Unit is the most important role in ICE.

    X-over :
    Why do you need tweeters, mid-bass woofers & sub-woofer in your car system? Each component handling different range of frequencies.

    Tweeter - about 2 - 20 kHz
    Mid-bass - 90Hz to 2kHz
    Sub - 20Hz to 100Hz

    So, when x-over receive signal from HU or amp it will filter and send HI-freq to tweeters, Mid-freq to Mid-bass speakers and LOW-freq to sub-woofer. Without x-over, you may fry individual component if it is overdriven.

    There are two types of x-over, passive x-over and active/elecronic x-over. Passive is the one comes together with Component Set Speakers.

    Active / Electronic x-over is the one need power supply 12v to operate. Also with many switches and selectable freq. Here, with a proper and sifu fine tuning, this is how you get a clean sound in a small room, your car!

    Get a Pioneer 5750(my previous HU) if you are a Pioneer kaki and budget limited. Now is around 650-700. If got more budget, can get 7750(I using now, 1200),6850, 9650, 8650. All of this has 3 pre-outs. Others have only 2 or 1.

    well, if have 3 pre-outs, then you will have front, rear and sub control. Better for future upgrade. The 2 you mentioned have built in XO also but only have 2 pre-outs.

    Looks like you have a good system to play with. Get a HU with x-over. I don't see you needing pre-amp if you have a built in x-over after upgrading your HU unless you wanna really fine fine tune.

    You have 4ch Blaupunkt + 2ch Mohawk, HEY hunt for HU with 3-pre outs. Better than getting a pre-amp.

    I hate gadgets, i just love power & clarity.:shades_smile:

    HU + CS = less potential noise

    HU + Pre-Amp + Active x-over + Amps + CS & Sub = WAHLIAO imaging potential of getting noise and amount of wires & cable to hook them up. (this is Grand-Father generation liao, no offense :_:)

    Aiyah, see wrongly liao, 6850 got 3pre-outs, not 2. I still prefer 7750 than 6850. 7750 screen bigger.
