Tweeter Pop - too much power?

I have a question that may or may have an easy answer.  None the less, I have exhuasted almost every option I can think of.  I recently purchased an Alpine MRV-F540 from a friend.  I was driving a set of Infinity Reference components and a set of Boston Acoustic Coax's in the rear.  In the dash I have the Kenwood DDX-7017 (supposedly 5 volt preamps).  At high volumes, with the gains on the amplifier at about 1/3 (fair below nominal & .5v) the tweeters begin to pop.  Some friends/coworkers suggested that the amplifier had too much power for my speakers and recommended I purchase a pair of MB Quart components for the front and just tone down the rear. 

So two days ago I installed a nice set of MB Quart Referenz Premium 6.5" Components.  These speakers are rated at 60-130 watts RMS.  My amplifier is rated at 80 watts RMS, (which this is supposedly very under rated).  After all of this work, I am still having the same problem.  At higher volumes my tweeters are still popping.  The Musicomp crossovers that are included with the MB Quarts are equipped with a light bulb that is supposed to "eat" distortion and clipping, but it does not always light up when this popping occurs. 

I thought maybe I needed better speaker wiring so this evening I completely rewired the component set with very large 12ga speaker wire, both from the amp to the crossover, and from the crossover to the speakers.  I still have the same problem.  I put a meter on the amp's power terminals, and at the highest volume, during the tweeter popping the voltage is still at 13.5-14.0 volts, (I have a 1 Farad Capacitor).  The only other things I have considered are, (1) that maybe my rear speakers are damaged (maybe not consistantly reading 4 ohms especially when the coil heats up) and possibly causing the amplifier to act strange???, (2) the amp is damaged (hard to beleive)???, (3) I have the amp at it's max and I want more than I have invested (which would just flat out suck because I guess we always want more???

I have been around and involved semi-professionally with car stereo for the last 4 years and I am very frustrated with my system at this point.  If any one has any ideas they would be greatly appreciated. 

Cheers,

Jon

Speakers pop for a couple of reasons.  One is over-power and the popping you hear is the speaker "bottoming out" or reaching its mechanical excursion limits.  Another cause is a crossover set too low for the speakers capabilities.  And a third is that the speaker is not causing the sound, the amplifier is due to clipping.  Since you are wisely using the factory crossovers you can rule out #2.  I suspect your problem is a combination of the first and third, especially after reading this statement:

(3) I have the amp at it's max and I want more than I have invested (which would just flat out suck because I guess we always want more???

What do you mean you have the amp at its "max"?  If your gain is too high the sound you hear may result.
