Question about wattage to subs-please help (1 Viewer)

[Shawn.G]

I want to use an old amp or receiver as a sub amp until I can get a PE plate amp. What is the least amount of wattage that can power a sub? What is the minimum generally, 100w? My room is 10.5 by 12, so I don't need 500w to the sub to make it overpowering. Thanks.

Well, Shawn, that depends on several factors. Most importantly, the efficiency of the sub driver will determine just how loud it will go with a given wattage. Also, exactly how loud do you want it?

It all depends on what the sub. It should have a reccommended power rating on it. Try to stay around that. Some subs can pull a lot of power, so if you underpower it, you could fry the receiver.
But any old receiver should work if it is around 100 watts. Just be careful not to turn it up too loud, and that the receiver does not get too hot.

So is around 100w ok?

Shawn,

I think 100W will be fine until you can get a plate amp.
