Grounded Door or HeadUnit Problem?

**athlon64** · November 21st, 2011 01:22 PM

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!

Binalik ko na sir kaso di namin mahanap yung problema. focus namin yung sa wiring sa door then yung headunit alone. weird kasi.. dami na din napupundi na ilaw sakin before ako magpasetup.. mga 3 times na.. ibat ibang ilaw.. wiring siguro to.. sana wag yung headunit kasi mahal..

There's definitely a problem on the speaker wire going to that door. It might have been pinched or abraded and either shorting each other or the metal door (ground) when it is opened.

You should have this fixed asap or you might just destroy the HU.

Nacheck na namin yung wiring from amp to seps-tweeter using direct ipad as source. Walang problema sir kahit iswing ko yung door.. Iniisip ko kung pano nagkaroon ng contact yung HU ko sa door / chasis kung grounded man siya? Tinanggal ko na din muna yung antenna baka kasi grounded din kaso same problem...
