    Good day!!

    I have audio setup on my Honda City 2004. Newly installed palang ito last two weeks. During the first week of breakin, ok naman yung tunog. We made some modifications sa mounting ng tweeter (nilipat lang ng pwesto). Problem now after installations, nagloloko yung balancing ng seps (Left-Right).. Nawawala ung Left seps-tweeter kapag open yung Left door. Pero pag sinaramo na yung door, tumutunog na ulit kaso pag malakas na yung volume, medyo bumibitaw bitaw ulit. Pioneer AVH-2350DVD gamit kong Head unit. Nag try na din kami mag isolate using ipad na nirekta na namin sa amp to check RCA/AMP/CrossOver/Seps-tweeter ang problema pero working fine lahat. kahit iswing mo pa yung door di bulibitaw. Iniisip na lang namin na baka grounded yung Left Door ko na in a way parang connected siya sa HeadUnit. (Pano kaya nangyari yun? Grounded yung Chasis nung HeadUnit na si door ang trigger? Grounded yung Antena ng Radio na si door ang trigger?) Kasi pag Ipad rekta sa amp to seps-tweeter ok lahat pero pag HeadUnit na source, bumibitaw bitaw pag nagagalaw yung door.

    Ano kaya sa tiningin niyo sir? Need your help...

    Thanks!

    Possible grounded yan sir, use multimeter para malaman nyo kung san ang grounded, because your headunit is grounded in the chassis of your car, syempre kapag one of the signal line is grounded to the chassis, mag mo-mute yung line na yun, suspek mo na agad is yung tweeter line na nilipat nga ng pwesto, now, you used ipod, directed to your amp, di kase naka ground yung ipod mo sa chassis kaya gumagana sya.
    Maaari rin naman na sa RCA yan, try swapping po yung left and right ng rca from your head unit kung ganun pa rin ang mangyayari, pag di lumipat ang problem to the other side, between amp and speakers lines po ang problema, you can see the problem by swapping each circuit one-by-one, for shortcut method, check the last thing you do before and after you have that problem...

Grounded? or Head Unit Problem?
