Will a multi channel amp run any hotter in high pass versus full pass mode?
I realize an amp will put out more power in full pass mode. But I run the same amp as a buddy. He runs high pass I run full pass to 6X9's both at 2 ohms and his amp run hotter. Or is it the speakers (we use different brands but both have passive crossovers).

Sounds like your amp is retaining heat...

I've never had an amp run hotter just because it was in full pass or high pass.
The amp doesnt produce more power because of the crossover settings but it will let more of the music throught to the speakers.

Yours is amplifing the bass notes his isn't.
The lower freq draws the most power.

Kinda true.
The amount of power needed to move a voice coil for low frequencies is much greater than high frequencies.
It's the speaker that draws the power. 200 watts to a tweeter is not the same as 200 watts to a sub.

Thats what I always thought. Sounds like my buddy needs better ventilation, better batteries, and a little lighter volume hand! :D :D :D

Ventilation is something you didn't address. Where are the amps located?
I was thinkin that one of your speakers is going to blow and causing really low load causing the amp to heat up...
Your a/b amp will run hotter than your class D amp... Gotta love digital switching...
I can wait to have MB's full range digital amp in our whss so I can play around with it... :wink:

Perhaps it's still hot from when the wiring shorted out?

Should I give it a couple asprin and a ice pack and see if that will cure it.

I think you should just sit down there with the stereo on with a Japanese face fan! :D

Actually after thinking about this again, I know what the heat problem is......
Here your poor little amp is working its ass off providing the whole sandbar with entertainment while your just sitting there drinking your GG&T's.....Maybe if you share some of your bar supply with the amp, the heat thing would just disappear into thin air! :D

Has anyone tried liquid cooling the amps in their boat? It wouldn't be tough to adapt a PC type CPU or chipset waterblock and install a small pump to circulate lake water.
:confused:
