TOPIC:

I have one of these Ice250 plate amps in a sealed subwoofer enclosure running two 10" 4 om drivers. I'm coming across this thing over heating and shutting down. I noticed that this unit gets up to 65deg C and shuts off, I think these units are poorly designed, they should be bolted to the rear plate and a heatsink used.

My plan is to add my own heatsink to this unit to keep it way cooler and so it can dissipate the heat better.

Something like this.

It will help the amplifier module stay cooler & last longer..

You will still be in a sealed enclosure though? I would suggest having a separate sub-enclosure for the amp and allow for ventilation over the amp module (that's how I use the 125s anyway )

the ice250 is in an enclosed part of the subwoofer, i plan on making two vents one at top and one at the bottom to allow air to move around, the heatsink should help LOTS too.

Cool. Please post pics when you do
