Is "turn on POP" caused by amp or head unit ?

[cichlid_baby 10+ year member]

I am running an Alpine 9886 and Sundown 50.4 Amp. I am getting the annoying "turn on POP" from my speakers.

Is anyone else running the same head unit and amps and having the same problem?

How do you get rid of this?

you have a bad ground somewhere start with amp and then head unit

I bought and installed the same exact headunit yesterday. I get the same pop sound from subs kickin on...

I think it's normal as long as yours isnt a humming sound.

Just wondering did you notice a loss in output from your amplifier to your subs? seems like my subs were louder off the stock stereo.

I have checked all my grounds.. all look good contact and have a direct path back to the battery ground.

Battery is grounded to Body/Chassis

Battery is grounded to Frame

Battery is grounded to Engine Block

Frame is grounded to Body/Chassis

Frame is grounded to Engine Block

Engine Block is grounded to Body/Chassis

Head unit is grounded to Chassis at kick panel

Amp is grounded to Body/Chassis and passes through directly to Frame

Remote wire signal is coming from Accessory wire under dash

There's not much to change on this H/U

What specifically should i check?

HPF is 80hz

Loud = off

Bass/Treble all adjusted

Subwoofer = 15/15

My grounds seem to be fine also, not sure why were having the same problem with the same H/u

Are you using some sort of Remote turn on relay?

I noticed with Alpine decks if you do not use the given Remote Turn on lead from the deck it will pop when turning on.

I thought my 9857 was bad since I was testing an amp out with a hot remote lead from the power supply but after using the one from the deck I never heard that pop when turning it off and on.

The given remote turn on lead was used in my install. Still pops

I will try to re-run the remote wire to see if that helps..

it sounds like it is your amp, I had a rf p300 do that, did a direct swap with an alpine amp that i picked up and it went away.
