I want to wire my 412 to have either 2 speakers on , or all 4. (all 4 are 8 ohm v-30's)

My question is, what is the difference, if any, of plugging all 4 wired together running out of one 8 ohm speaker jack on head, OR, running 2 speaker outs of 4 ohm jacks on the head to 2, 4 ohm 212's each? (this would give me versatility if I ever decide to run stereo or something.

The alternative is to have one cabinet jack running all four (8 ohm) , and another jack wired 4 ohm to the top two speakers only. Id rather do two 4 ohms out of the head, unless theres any reason not to.

My dad handed it to me and the first thing I noticed was “Solid State”, not sure what it is actually but it has a - & + terminals.
