    'm currently running a 450w @4 ohm head thru a 4x10 cabinet with 450w @ 4 ohm impedance. Due to the current situation im in, i need to get another cab. My question is, does the 2nd cab have to have a 450w @ 4 ohm impedence, or only half that? Thanks.

    If your head is only designed to push 450w into a 4 ohm load, and you are providing it a 4 ohm load, you cannot add another cab.

    Adding another cab (in parallel) would mean a load less than 4 ohms and possible damage to the amp (assuming a solid state amp). Adding another cab in series would change the load to 8 ohms, and you would probably not gain any volume as the amp would probably only make 300w or so into an 8 ohm load.
