Hi, all. I have this oldschool RF bd1500. It has a "pop up" noise every time i turn on the audio. Already try to replace the mono with another mono and no "pop up". So i guess sumtin' wrong with bd1500. Already bring it to local technician but got no luck. Any idea where should i check? Coz, i have several friends having oldschool bd amps and most of them having the same problem.

Are you saying that the speaker pulls in or pushes out when connected to the amp?
Please read the entire basic amp repair page (even the parts that you feel are irrelevant).

I can't see it. Cuz, i have a bandpass box so the sub is inside the box. 🙁
I try read your article first.

Do you read more than a fraction of a volt of DC across the speaker terminals at the time when it would pop?
Disconnect the speaker wires from the amp when measuring the voltage.
