Default Clarion Head Unit Cutting Off/On

Hello everyone. Just found this forum and have been having fun looking through all the posts. Tons of great knowledge here!

I have a 1994 Chaparral 2130 Sport/SST, with a 7.4L Mercruiser Bravo One, which is still mostly in "showroom" condition, even with just over 600 hours on her. I keep it garaged, clean it after every use, and maintain the engine per Mercruiser specs. I mostly go to lake Allatoona, with regular trips to Watts Bar lake, Savannah, and the northern Florida gulf. I have so many things I've added to the boat since she was delivered, and all the installations went smoothly, but one item is driving me crazy.

A couple of years ago, I bought a new Clarion XMA1-R head unit (yeah, I'm an old guy who still loves his huge cassette collection), and a Clarion DC625 6-disc CD changer. Last year, I upgraded my old amps to a couple of Pyle Audio 400 watt boomers. Pushing 8 speakers, the sound is excellent. However, I have one problem with the XMA1-R cutting out when I hit a wake. Its as if the power is cut off momentarily, then it comes back on. In rough water, it constantly keeps cutting off/on/off/on... It will do this whether I'm listening to the radio, cassette or CD. I've checked the power connections and even reseated the connector plug a few times.

Has anyone ever heard of this problem? Any and all suggestions would be greatly appreciated!

Oops. Figured this one out. Finally finished going through every single thread in this forum and found some advice on wiring. In my troubleshooting, I had only traced the hot wire and ignored the negative side. With the head unit on, I started giggling all the wires, all the way down the line and sure enough, the negative wire, where its screwed into the buss bar, had a loose ring terminal. Replaced it, and everything works fine again.
