use a relay i got that. next question what needs to be done to make a 4ohm amp stable at 2 ohm im pretty good with electronics and built amps when i was younger i cant remember all the theory but could definitely do whatever needs to be done im good with a soldering gun i dont need this i just think it would be fun to do
Best Heat Sinc i ever used was the TermalTake Big Typhoon... it kinda looks like an Engine hovering above the Chip... Its big ... almost didnt clear my case but it is awesome!
class AB amps always run hot.
if you need a mono 2 ohm amp, go buy a class D amplifier. it'll run cooler, and it's made for what you're doing.
it'd cost more to rebuild the amp for lower loads than it'd cost to buy a new amp.
i like to overclock computers alot and i thought i could cheaply overclock and amp but from what ive read the answer is no. i think full immersion cooling would look really cool and i may do something with that this summer.
