2001 SAN stereo cutting out

[diesel33]

Stock cabin speakers and clarion h/u, speakers would pop when the volume would turn up. I replaced the cabins w/ polk db651s and the first time I turned the volume up, they popped. The h/u now is cutting out on me, is it possible I knocked a wire loose? Or is the headunit going on me?

Thanks

I had that stock Clarion in mine. It was just too old tech for me so I replaced it with a Kenwood that you can put your ipod inside.

Could very well be a loose wire. I would start there. But, it could also be the head unit dying. More likely a loose wire though, assuming your clarion unit is the factory marine unit.

diesel33,
The fact that you have a popping when you raise the volume would indicate to me a problem other than an intermittent connection.
You could have low voltage. You could have an issue where the independent grounds for L, Right, F or Rear could be reversed. You could have a source unit that has incurred water damage.
First, check the voltage.
Second, wire up a single speaker only with the other three disconnected. Make sure that the speaker positive and ground are part of the same channel. If problem-free then add in one additional speaker at a time. Verify that no load is less than 4-ohms.
Third, inspect the source unit chassis inside and out looking for a white residue (mineral collection) as an indication of water damage. If you find this then use tuner wash and a Q-tip or very soft toothbrush to remove the residue.
After that you should know if a new source unit is needed.
