We have a Clarion system with 25 rms per channel X4. It has an I pod jack and is hooked up to two Bose speakers in the cabin, Flatscreen TV with DVD plays through it.
Also I put two marine bose speakers in the cockpit> I threaed up through the pedastal tubes the remote to the clarion and installed it on my navpood on the helm. From there you can:
Turn it on and off, switch the IPOD tracks, adjust fade ( inside the boat and outside in the cockpit as well as balance, base etc.. Wasnot hard to do.
We dont listen to music much on the bay when sailing unless its a long trip or we are in the slip or anchored. On our trips to NE or the LI Sound thats a different story.
