help with head cab stuff

how do ohms watts and stuff mix and match? the head says: 130 watts and 4 ohms by the output in the back, but in the upper left hand corner it says it is 400 watts 60 HZ. i'm confused?
 
Re: help with head cab stuff

ths cab says 16 ohms, 4 ohms (mono) and eight ohms (stereo). there is a switch between 16 ohms mono, and 4 ohms mono

the 8 ohms stereo is under the 4 ohms mono.

it is located right under the and. get it????? lol sorry.

there are two inputs and one output. but in the input it has left right, and 100 watts 50 watts per side. i don't get it.

Well your amp has more wattage than the cab can take. Avoid it or be careful. You would run the 4ohms out of the amp into the input of the cab. Make sure the cab switch is on 4 ohms mono.

i switch it to 4 ohms not 16. and then i could use it without a problem?
 
Re: help with head cab stuff

the output of the head says 130watts 4ohms. but the head says 400w.

but there is no switch on the head that says 4 ohms or any switch on the back of the head at all.

plug the speaker output of the amp into the 4 ohm mono input of your cabinet. simple as that. however, as YJM already pointed out, your amp puts out more power than the speakers are rated to handle, so you do run a slight risk of cooking your speakers if you push them too hard.

as for the 400 watts / 60Hz thing, ignore it. it's probably just indicating how much power the amp consumes from the wall, as 60Hz is the frequency at which the AC in the wall is in the US.

also, if it's a solid state amp, i believe you can get away with running the cab in 16-ohm mode and get a drastic cut in the power coming from the amp, so you can run it at higher volumes and not worry about your speakers.

it is solid state. so i dhouldn't worry?

well it is actually 130 watts but it still more power than the cab.

yeah, if there's no impedance switch on the back of the amp, then 4 ohms is the minimum load, and a cab with greater impedance would get less power from the amp. example: i have a power amp that does 300 watts into 2 ohms, but only 210 into 4 ohms, and 170 into 8 ohms. so if you have a higher impedance cab, you'll get less than 130 watts, possibly a lot less.
