Speakers pop when HU turns on?

[-DarkMatter- 10+ year member]

I've had this problem for a while now and I just want it to go away. When I turn on my Alpine HU the 4 speakers in car make a pop sound. There is no engine noise whatsoever, and the only time they make a pop sound is when the HU is turned on...not when its turned off or changin stations/cd's etc. I'm thinking over time if I let this go the speakers will eventually get damaged from this.

I have an Alpine CDA-9807 hooked up to a Mach 460 system that Ive replaced the speakers on. The speakers are powered by amp as well...my sig has details. I have the bass boost completely off, crossover off, and gains 3/4 way up on amp channels.

Think I might have tracked down a similar problem in another thread where someone suggested to put a 1k resistor on the remote wire? Would that work?

Ok you mean the HU ground or the amp ground....I thinking you mean amp ground?

well if the speakers are amped then yes the amp ground, if its powered by headunit then headunit ground

either way, ground

My system started to do this when I installed an RF symmetry. It ended up being that I was sharing the ground with my 2 amps and the symmetry. I took the symmetry off the shared ground, found a new point and it went away. Never hurt anything though.

another thing that you can do is run regulator from RadioShack item number 276-1770 in your remote wire and that should also solve the problem.
