I just replaced the tower speakers a couple days ago, and ever since my PDX has been over heating. Leads me to think the speakers are too much for it? However, this is also the first really warm weather we've had too. First day we've used boat in air temps above 75° or so and all these days have been 90° plus.
Now here is where it gets a bit strange. The PDX is 5 channels. My tower speakers are actually bridged onto two amp channels and then split again in the cans. Strange I know, but the factory speakers in these cans had a built in crossover in the can and it split again after the crossover for each speaker. When I installed new speakers, I didn't want to run more wire into the tower so I used the existing wire and just split once in the can.
Could that be the cause of the amp over heating? My first step was to turn the gain down on the amp. That didn't really do anything. Next I turned down the sub at the HU, still gets hot and cuts out.
Ideas.....? Go!
