Speaker Popping Sound

[amdrocks]

I have a used 2000 GTZ that I have owned for a year now. Lately, the rear speakers have this popping sound. I have searched online for it and consumerautoguide says it might be due to a short when the power seat is operated. But it does not pop only during operation, it also pops when no one is sitting in the car. The Mitsubishi dealer wants $100 just to diagnose the problem. I have removed the HU to have a look at the cables as well as the amp underneath the passenger's seat. Seems like the connectors are secure. Does anyone have an idea what else I can check?

Thanks!

Does it pop by itself when the car is off with no music playing? Or does it only pop along with the music?

[amdrocks]

It pops whenever the HU is on. Like when playing music or when volume is zero.

[Jeffylou87]

It's either the HU or the amp..

[amdrocks]

Meaning to say one of them is faulty or one of them is shorted to GND?

[Jeffylou87]

Faulty.. If it was shortened, it wouldn't work at all..

I was checking online and found this MITAH adapter. Thought of buying one to connect to my MP3 player but I realized that there are 4 RCA cables. Does anyone know what these 4 RCA cables lead to?

[Jeffylou87]

The MITAH adapter is so that you could use an aftermarket headunit with front a rear audio out.. All it does is convert that plug into rca's so that you could put an aftermarket radio in there..

As in like is 1 pair for the front speakers and the other pair for the rear speakers?

[Jeffylou87]

Yes sir.. I have one in my car..

[amdrocks]

ahh... okay that's good... now i'm just waiting for my midterms to be over before working on the problem...

did you upgrade from the 4 speaker system or infinity?

[amdrocks]
