I have just replaced my front speakers (MB Quart - Component) and rear (MB Quart - Coaxial) and they sound great!

Then I went ahead and replaced the Sub (Pioneer - Free-ar) and Amp (RF). The system sounds awesome but there one problem....

There is a POPPING sound everytime I turn on the power. Does anyone know what is causing it?

Thank you in advance.

Try turning the gain down first.
What model RF' are yoo using? It may not have 'soft start'.

I did try tuning down the gain but no luck... I'm using the Punch 360.2 Amp. I do believe it has the "soft start" feature. thanks

 

I'm moving this thread to the Electronics forum where members are better able to help you.

 

it could be from one of your ground wires check those out, are you still using your stock deck that could be a problem too

 

are you running a remote turn on wire. esp with a stock head unit. u need one. do u hear the turn on pop noise everytime u turn on the radio? i have a turn on wire with switch and ocassionaly i will hear the noise when i turn off the radio or on. even sometimes when i start the car. but it happens like once in a blue moon. i dont get it. it is definitly annoying though. esp when u have over 1000watts and three 12's making a loud *** poping noise. i praticaly jump and get scared lol.

 

thank you everyone for replying.

I hear the POP noise only at the turn on (not during or turn off). I am using the stock HU and am running the remote turn on with the HU. I have also moved my ground wire around to 3 different locations but still no luck (scrapping out the paints at the contact points, too). I made sure that there are no wires crossing.

If it is the stock HU that's causing it, then I'm out of luck and would need to bring it to a Pro to replace the head as well, since I'm a newbie to any audio systems. But that is the last thing I want to do becuz I prefer the stock looking console.

three 12s making that pop noise?!?!?! Ouch.. One already scared the **** out of me; I can't image 3!

thanks, again.

I think you need to delay the turn on signal to the amp at bit, ie 1/2 sec probably do the trick

try this:
disconnect the amp turn on wire, turn on your head unit, then reconnect the turn on wire a few second later==> see if you get the noise or not? (repeat it several time to make sure)

if that fix your problem, you need to build or get a small delay circuit that would delay your turn on signal for 1/2 sec or so, i set mine at 1sec just to be sure

 

ok if i need this device, where can i pick one up, what does it look like etc.

 

it's a simple RC circuit, I built mine for a few bux
but you can get a better ones here

make sure you test out based on my instruction from previous post, just to be sure that adding the delay will cure your problem.
