First I want to thank everyone for jumping in and trying to assist me with my difficulties. I especially shout out to MrMiati for going the extra mile and doing the research for me to educate me to the extent of the problem I was dealing with. He did not have to do this and I am extremely grateful.

Pizza: To answer your question, your surmise was correct, I did not change the back woofers. I only changed the door speakers. To your point---I ran the Kappas for a week with the rear woofers while I awaited the kicker tweeters. I ran them thru the factory amp. Had no problem and everything was clear and crisp even at max volume. It was not until I plugged in the kicker tweeters into the equation (plugging them also into the factory amp) that i started getting the shut offs, even playing at low levels. So, I am definitely overloading the amp.

Pizza I see you are a Kenwood rep. SO, my question is aimed at the Kenwood unit itself. I am using the speaker wires in the head unit wire harness to connect the door speakers (door woofers) to the amp. What wires would there leave in the head unit harness to use to directly connect the tweeters to the head unit. I am at a lost because I think there is only one set of wires for the speakers and I am using them for the door woofers). Am I missing something here
