Wierd Car Audio Issue

[nevadaspierce]

MY CAR STEREO SYSTEM HAS A PROBLEM THAT I HAVE NEVER ENCOUNTERED BEFORE. THE AMP GOES INTO PROTECT MODE WHEN CERTAIN THINGS ARE DONE OR HAPPEN, I WILL LIST THOSE THINGS MOMENTARILY. HOWEVER, I CANNOT PINPOINT THE PROBLEM, AND I HAVE SWAPPED OUT THE AMP, REGROUNDED IT TWICE, AND REPLACED RCA'S, ALL THE SPEAKERS AND SPEAKER WIRE HAVE BEEN CHECKED REVEALING NO BAD SPEAKERS OR SHORTED WIRES, AND STILL HAD NO LUCK IN FIXING THIS PROBLEM.
WHENEVER I AM LISTENING TO THE RADIO, FM OR SATELLITE. IF THE VOLUME IS UP OVER HALF WAY, WHEN THE MUSIC STOPS AND THE DJ BEGINS TO TALK, THE AMP GOES INTO PROTECTION. IF I AM LISTENING TO A CD AND CHANGE SONGS TOO MUCH OR THE CD SKIPS, IT WILL PUT THE AMP INTO PROTECTION. I CAN ALWAYS TURN THE HU OFF AND TURN IT BACK ON AND THINGS WILL FUNCTION AGAIN. BUT TRYING TO LISTEN TO THE COMEDY CHANNELS ON SIRIUS IS A LOST CAUSE. ANY DIALOGUE LASTING MORE THAN A COUPLE SECONDS WILL ALWAYS TRIGGER THE AMPS PROTECTION CIRCUITRY. MY SYSTEM IS AS FOLLOWS:
PIONEER DEH 740 MP W/ 3 PAIR OF 5V PREOUTS
ORION HCCA 425 PUSHING 2 PAIR OF MB QUART SEPARATES AND 3 4OHM KENWOOD DB+ TEN'S. EVERYTHING IS WELL POWERED AND GROUNDED, THE RCA'S ARE PHOENIX GOLD'S. I HAVE NOTICED THAT IF I TURN THE SUBS OFF BY SWITCHING OFF THE OUTPUT ON THE HEAD UNIT IT TAKES LONGER FOR THE AMP TO CLIP BUT IT WILL STILL SLIP INTO PROTECTION IF SOMEONE ON THE RADIO IS TALKING???

nevadaspierce,
Welcome.
Just a guess: did you connect the speakers in respect with the amplifier's minimum load impedance?

Oh..and please hit the caps lock button in your next post.

nevadaspierce,

Have you checked that none of speaker leads have no connection to ground or to eachover?

nevadaspierce,

Have you checked the ground to make sure it is tight, clean, free of rust, and is bare metal (no paint)?
