Kicker 700.5 Going in to Protect Mode - No sound from cabin speakers

[Poison]

It is the subwoofer. Disconnected the RCAs and the other cabin speakers worked fine.

If I dial down the gain on the sub the amp does not go into protect and it still functions. When I put it back to where it was it instantly goes into protect.

I am reading 12.8 volts at the amp power source.

To clarify, this is after I plugged the subwoofer RCAs back in.

So amp work fine with woofer disconnected. Reconnected, you can prevent protect mode by turning down the woofer gain? Where is it set at in terms of clock position or %? I would dig deeper into a possible woofer issue. Unless you are certain the gain has been turned up recently, prior to the issue?

Correct. I turned it up at the beginning of the season.

Here is where it is now. Before the issue it was 3 clicks to the right...halfway between the current tick mark and the next. I'll assume that is too high in your experience?

Too high too low is relative. Some unknowns here so really cant say. However, I typically dont get concerned about gain levels until we get past 50%. The other tuning adjustments as well as the pre-amp level will play into the gain level, not to mention the speaker and how its loaded. Cross over looks a little low.

Understood. I get that most of this is relative...I've followed these forums long enough to know I don't know much.

The sub is the stock 10" Kenwood that came with the boat. Loaded directly into the kick panel and not properly enclosed. It is as old as the boat (10 years) and not a marine speaker so if it is going, I guess it has had a pretty good run.

Also, is there a rule of thumb for the LPF? About what would you expect to see?

80-100Hz depending on woofer.
