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?
Honestly speaking, did you or did you not short-circuit your system recently? nop What brand and model of HU your are running currently? pioneer 3750 How does this AEROPLANE started to FLY on the front left channel? 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:
wat i really concern rite now is the radio frequency sound alike while im playing cds on my HU.....whether it is ori or cetak rompak cd......the sound still exist whenever the song change tracks! really curios bout this matter........b4 i install the 4 channel amp,that sound did not appear! What The F@@k........ does anyone experience these kind of sound b4?:baring_teeth:
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?
i wil try 2 bypass it when i hav time.... now 2 bz wif work here n there..... if the frequency sound does not appear when i bypass my preamp,i will make sure that the preamp is going 2 slip in the tong sampah...... FYI,my HU is just one year onli....it is the second latest model from pioneer b4 they produce the new 3850 diz year! if the HU is the cause of the frequency sound n aroplane sound.....i wil change it in the future wif dvd player plus monitor 2 play my PS2 inside my car....... HEHEHEHEHEHEHEHE Cheerrrrrrrsssssssssss mate....thanks 4 ur advised! :shades_smile:
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
ok bro,thanks 4 all the advised i wil survey the pioneer 5 and 6 series soon will sell off my current HU...... the preamp will b in tong sampah when i got time! bro,wat is the use of e-xover ha? c ppl use,but dunno wat for? explanation pls......:shades_smile:
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!
thanks mate 4 ur detail explanation! here is my ICE HU pioneer 3750 Subwoofer mohawk plus 2 channel amp also mohawk 2 Component set brand PEGASUS Blaupunkt 4 channel amp for my CS then the worst thing is my preamp CAP AYAM! 1st thing i wana do now is to take of my preamp then search 4 a new HU that have built in xover! then search 4 a better preamp as well! lot 2 do but need time! HEHEHEHEHEHEHEHEHE CHEERS MATE! HAPPY ICE:shades_smile:
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.
bro kyheng, wat is the use of 3 preouts, as compared wif HU that only hav 2 preout? does 5850 or 6850 hav built in xover? thanks in advance......:shades_smile:
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.
how much is the market price for 7750 n 6850? which one goes better wif my current ICE setup? thanks...:shades_smile:
oh guyssssss......... know wat? i hav juz browse through the pioneer web searching 4 the 7750 n 6850 info now i know that my 3750 really out of date n cannot satisfied me in terms of sound tuning and sound quality.... now hav 2 save money 2 buy 7750! from wat i can c, 7750 is better than 6850 in many sense..... haiya,money!!!!!!!!! the 7750 got so many things 2 play wif.... shit man, i really wan it! ARGHHHHH:baring_teeth: :baring_teeth: :baring_teeth: guys, any price list for 7750?
