Hi all,

I have a jl m series 600 watt at 4 ohm amp. I have it running at 4 ohm currently driving one sub. The boat is used at the river where it's commonly 120 degrees. I have it in the cabin which is shaded, but still hot. Are you guys typically running amps with headroom as far as ohms, or are you loading them down on occasion to their lowest ohm load when using them in a hot environment like this? Temps are always above 100 degrees and usually above 110.

I’m in Arizona, and in the summer I don’t have problems. I do the lowest ohms the amp is capable of, but I always like to have lots of headroom on watts. If I need 500 rms, ill get a 750 watt amp to keep the gain lower.
