Amplifier grounding and gain setting. Also quality of signal to the amp (RCS cables, etc.) and quality of the speaker wire to the tweeters. Are the woofers "popping" too or just the tweets?

Yea like Dyohn said you may want to check that ground. I've seen a lot of things go wrong because of a bad ground.

they only pop at loud volume. speaker wire is good. also, theRCA are ZeroNoise 3.5's by whoever makes them. think it would stop if I drop the gain on the amp?

Chcek to make sure the ground is good and solid and is an unpainted bare metal connection to the chassis of your car. The gain should be set to match the input from the head unit. Was it set up properly, or just plugged in and turned on?

Tweeters (or other speakers) making a "popping" sound can also be from overdriving them at too low a frequency. This will blow them in short order.

I will check the ground. They have crossovers in place, so it is not a frequency issue. If that is all the power / volume that these speakers can take, I will never go JL again. I know it is good clean power. I never have been a fan of JL and this is my first experience with them. Not exactley thrilled.

And also make sure the amplifier gain is set properly.
