I only heard the mid popping, not sure if the dash is popping also.

cause i'm wondering if it's something to do with the stock crossover between them or the wire from the cross to the mid or maybe a defective mid.

might be a bad mid. it was acting weird before, but it never popped.

nevertheless, going to remove almost everything and try and figure this out...

its also imprtaint to keep you wires seperate. i always run the power wire down the driver side, the RCAs down the pasenger, and the remote wire down th middle. this way no unwanted signal can cross over, like an RPM noise or a speaker of a poping sound from power on/off.

I took all the unnecessary wiring out. The amp and sub worked fine. But the popping in the front right speaker is still there. When I unplug the speaker, I get no popping... so either the speaker is bad or my amp has a "hard" turn-off.

I also noticed that when I turn on the car, the bass notes from the song will start about .5 seconds before the music does, weird.

that last part would make sense a bit though, the HU should have it's own safety breaker which holds back your mid/highs making it result in hearing the bass before the rest of it all. i'm also wondering, if the fail safe breaker on your HU is heavy duty or not and if it's causing the pop? when you turn the system on, do you here a click sound from the HU just as the mid/highs begin to play?

I def hear a click when the HU comes on. Never really paid attention to where its coming from though.

either from the amp in the back or the HU it's self aswell. that click can very well be the cause of the pop. the click sound comes from a breaker built inside of the amp module known as the fail safe breaker. this is part of the "protection mode" and over heating saftey features and is activated by unstable voltages and high amounts of heat. when you turn the HU on and that click goes, it means the fail safe has turned off and gone into standby so that you may use the unit but can very well cause a "pop" noise through the channels being that it lets through all the master power into the amplifier modules and is exactly why pro audio amplifiers do the same pop noise through speakers is and when the sound processing unit is turned on before the amps are. in your case, you can't really control that function, you turn your soun processing unit *the HU* and it's on before it's own amplifier modules are on so that part COULD very well be the issue and if that is it, then it's nothing to worry about and is perfectly normal, though annoying, it's find. just don't have the volume way up when you turn you car off at night... turning it on in the morning will be disasterous *blown right speaker if the volume is up, the fail safe will allow all that energy at once through that pop and will rip the cone right off it's VC*.

man, you have been unbeleivably helpful!!! THANK YOU!

I knew it wasnt a problem per say, just really annoying. And the advice you gave, is something I do all the time (turning it down or even shutting the audio off from the HU when I shut the car off). You just confirmed my thoughts.

no problem, though i would still check to make sure if it's something to do with the right side cross over or the speaker it's self. try switching your front mids around and see if the pop hits on that right side again or if it's moved to the left. crossovers are not always perfect and you said your self it was acting up before. have you had the same HU all this time and just down graded on number of amps and power?

yeah, Ive had this HU from day one. I had a few different amps in there but nothing as powerful as this one. I think all my amps before combined to what this one amp produces.

Im going to put some Kicker components in the front with another Kicker amp. If the speaker pops, then its def what you described above. If it doesnt pop, then its def the speaker or the crossover...

good thinking, i have a strong gut feeling it's the fail safe but i still wouldn't throw the idea of the crossover and then mid speaker it's self out te window just yet but i guess we'll wait and see huh? haha, good luck!
