Will larger speakers require greater power on a modified handheld radio.

Ok, so I'm pretty darn new to engineering, so I'm just diving in and hoping all goes well. I've got roughly 6 months to finish this project as it's a Christmas gift in the making. My current plan is to carve a large spruce log into the shape of an old cathedral style antique radio, make a cabinet, knobs ect.

Then, insert a handheld radio, modify a larger speaker and a stronger antenna onto it as well. And I'm wondering, will I also need to modify the battery box to accept more than 2AA batteries, or would this power output still be enough to power everything including the LED indicator?

Generally, a bigger speaker would require much more power considering its wattage and supply needed. It would be best to indicate what is your circuitry,the components most specifically.

Thank you for your reply.

The exact radio model I'm gutting and trying to improve for the project is this one > http://img.dxcdn.com/productimages/sku_241705_1.jpg

If your referring to connecting it as a whole, I think I'll stand with what I said that it would require larger amount of power. But if its just a amplifier of some sort,that would be different. Since It would have its own power.
