HELP! Speakers Keep Shutting Off!!!!

Hey guys it's me again.

OK, here's the story. I just installed a decent system in my 2005 Nissan Altima 2.5 SL w/ Bose. You guys helped me alot in deciding how to configure the setup. But now I have a problem. I originally had an Alpine PDX 2.150 amp powering 2 Alpine Type R SPR-17C's 6 1/2" speakers for the front doors and 2 JL Audio VR690-CXi's in the rear deck. I ran them in parallel like I was instructed to do so but they kept blowing the fuses out in the amp at a high volume. So then I took it to the shop and they told me that one of the JL's got damaged from the amp so they had to replace it and also turn the gains down a little on the amp. They did that but still afterwards the speakers kept shutting off again. So now I just purchased the PDX 4.100 to see if this will alleviate the problem. I hooked everything up and it worked fine.....FOR LIKE 1 WHOLE MINUTE!!! I have a Pioneer DEH P5000UB HU. Before, when I turned the volume past 30 the 2 front and 2 rear speakers would shut off. Now that I have the 4.100, when the volume is past 50 they shut off. The store rep told me that the Alpines might be damaged as well but even they are not sure because when they checked them they seemed to be fine. There is no distortion or clipping or any kind of static whatsoever coming from the speakers. They just keep shutting off on me at a certain volume. I would also like to add that with the PDX 2.150, when it used to shut off I had to replace the fuses but with the 4.100 I just have to turn the HU off and back on and the speakers work fine again. I took it in to get diagnosed and they checked all the wiring 3 times and everything is wired fine. Do you think that the 2 front Alpines might have been damaged from the PDX 2.150? Do I have to replace them? Could it be the HU? I did everything you guys told me to do. I bypassed the Bose and everything.Please, I need help on this it is driving me absolutely nuts!
