Sup,

I recently bought a Dayton Sub-120 about two weeks ago from parts express and i'm pleased with it for the price.

However, after listening to music for about an hour (rap music - heavy bass) the heatsink on the back get uncomfortably warm/hot, in my opinion, although i don't know what hot really is.

I'm running it through the pre-out on an Onkyo TX-SR601 to the low level input rca (split left/right).

Should i worry about the amp burning out?

Anyone have a Sub-120 that has input on how hot it's running?

Are you pushing it a little hard? The heavy bass will heat it up pretty fast.

It will get hot. Estimated around 150 to 170 after a few hours...medium level playing. 150 watts, no fan. Its uncomfortable to touch, but not like touching a stove top.

Good rule of general heat estimates from Chemistry class:

If you can hold your palm to it - get warm, not uncomfortable 105 - 115

can hold palm on it for 20 to 30 seconds before uncomfortable - 115 - 130

10 to 20 seconds - 130 - 150

immediate uncomfort - 5 seconds 150 - 160

less than a few seconds 170 plus

Construction workers and guys who watch porn all day.....add up to 10 seconds to each sensory rating.
