less ohms = more heat?

[sdime808]

I have two 2ohm DVC IDQ's and a Soundstream ref 500s which is 2 channels. I heard that this amp can really heat up so I want to configure it so that it runs as cool as possible. My options are to run it at 1 ohm on each channel or 2ohms bridged. Is it safe to assume that running it at 1 ohm on each channel will make the amp hotter than 2 ohms bridged? will there be any other effect?

Power is power. If the amp makes the same power (combined) in both cases, it doesn't matter.

So power makes heat? not resistance? is that correct?

resistance effects heat - indirectly. As you lower the impedance the amp will be able to generate more power - which is where the heat comes from.

It's really not an issue with your question anyway, because to the amp - 1 ohm stereo is the same as 2 ohms mono. It will make the same amt of power.

I asked that question because I wired up my subs at 1 ohm stereo and put it in my box and everything. I haven't tested it yet but I just realized that I could have wired it at 2 ohms bridged with the same power. Now I'm having second thoughts about leaving it at 1 ohm, and if it will function with less heat at 2 ohms bridged then I guess I'll take them back out. But that would mean desoldering and resoldering my connections. I only want to do that if there will be a significant difference in heat produced. Thanks for you replies though!
