Fender Amp Question?

[bordinco90]

Hello everyone. I have a Fender Rumble V3 2x10 Combo Amp. Today, I practiced with my band (2 loud guitarist, and a loud drummer) and surprisingly the amp held its own. I am probably going to get the 2x10 extension cab for it. My question is, will the extension cab make my amp noticeably louder? Thanks everyone! Help please.

Yes.

reading the specs, it says 350W/8 Ohms and 500W / 4 Ohms. but doesn't indicate a socket for the extra cab, I assume it's there or else why the two power figures?

So , it puts out 350W as is, adding another cab will increase the output to 500W. Also you will double the speaker size so yes, you will notice a greater volume.
