so my amp head has thingy that says "120w at 4 ohm"
and the back of my cab has a pluggin that says 4 ohm
but it also has one that says 16 ohm, and when i plug it into there it only
uses the 2 right speakers.

I would think (4) speakers at 16 ohms would be 4 ohms (2) 16 ohm speakers
would be 8 ohms and one speaker at 16 ohms?
It depends on how they are wired parallel or series.

that was super confusing, its an epiphone triggerman cab.
and its no wheres near as loud as i expected,
right now were running vocals through a fender 120w combo amp with 2
speakers, and i can hear that just fine even with my amp cranked, i know
they are both 120w but, youd think the big ass cab would be louder.
needless to say im dissapointed.

Chris, you've got to understand that running your amp at improper ohms can
cause some unwanted results (as you described), but it's also really bad
for your amp.
I've found that wattage isn't always an indicator of 'loudness'.
I've got 15 watt Class A tube amp that I run at 8 ohms with a pair of 12"
Celestions - it smokes almost anything as far as 'loudness' goes. 15 watts,
dude. I'd venture to guess it would smoke that combo your using for vocals
(not to talk down).
The thing that's happening with your 16 ohm jack... that's your cab trying
not to let the amp cook itself. If I had a dollar for every guitarist who
blew an amp because they didn't understand ohm-age... well I could buy you
a pizza. Bottom line - keep 'em matched. Make sure your amp and speaker cab
are set up to use the same resistance (ohms).
Good Luck!
