I have an rsd10d sub running off of an rsd 300.1 amp. I am thinking of adding another rsd10d sub. Will the 300.1 amp power two rsd10d subs?

Thanks for your help.

I really don't think you would have enough power. get a sub and another amp or just a bigger amp

A 600.1 would be just fine..........

The problem is the load. With two 10D's you can only run 1 or 4 ohms to the amp, which is designed for 2 ohms. With one 10D you can do 2 or 8 ohms, which is perfect.

If you went with two subs at 4 ohms, it would be no louder than your current setup (half the power = -3dB, but double cone area = +3dB, so 0dB difference). If you went at 1 ohm the amp would be stressed, draw much more power, get much hotter, not sound as good, etc.

if you want more volume, i would instead move to a rsd12d or even a rsdc if you can find them for a good price.

as mentioned above. adding a second sub wont be ideal for the amp and not net you very much volume, if any
