Can tweeter turn on pops be harmful?

Just installed an alpine pdx f4 to use in an active 2 way setup and there's a slight pop from the tweeter when you turn the car on. I dont really mind it but can it harm the tweeter? I have a cap inline

If you have a cap inline its not active. Active is crossover before power. It shouldnt harm them but it should be fixed

What is triggering the amplifier to turn on? Is it turning on before the head unit? The capacitor is providing some protection. Don't remove it.

Its only used for protection, cuts any frequencies lower than 1325 hertz. I have the HPF for the tweets on the active crossover set to 3500 hertz so its fully active

The remote turn on is triggering it (no relay) and its hard to tell, they turn on pretty much at the same time.

Just unplugged the RCAs and turned the car on, still popped. I guess its the amp, is it worth sending it back for a replacement?

What's the head unit? What's your tweeter amplifier?

HU is 80prs and the amp is an alpine PDX F4

There's not enough delay time from power source, it's like pulling off the RCA's while operating in high volume.

Contact Alpine. With this level of quality equipment you should have soft turn-on in the amplifier.
