Mike, explain a little more about this if you could "running the Deck at 75 to 80%", what volume on the head unit should I run at, seams I did have it a higher number sunday vrs last year.

is the headunit volume not supposed to have a effect on volume coming out the amps to the speakers?

What i mean by this is if your using the RCA the decks amp isnt working very hard. Its only pushing a Low Voltage signal but yet it still clips and causes distortion to the amps if you go to 100%.

If you wired Speakers directly to the deck and pushing it at 80% then the amp will heat up as its working because its pushing a lot of power to those speakers. High Voltage signal.

Voltage signals are hgh and low in relation to the decks output not in relations to say a battery LOL. Just figurative speaking.

As for the Harpoon if your left 2 speakers are wired together to drop to a 2ohm load then the Harpoon is going to be fine.
Last year over the winter my Harpoon had a channel go bad over the winter. I had no sound on the left 2 XM7s and when i switched the speakers with the right side, the Left side from the Harpoon still didnt work.

If your moving the suspected bad speaker around and its not working them yea its the issue, as long as you can get a known good speaker to play in the suspected bad speakers original location then the speaker its self is the issue.
