16 Ohm cab and 8 Ohm cab...using them together?

[Myriad_Rocker]

I just want to cover my bases before I go plugging things up. I've never messed with a dual cab set up. I'm sure it would be easier to just have two 8 ohm cabs, but I don't.

So, one amp head and two cabs. One cab is 8 ohm and the other is 16 ohm. How to hook them up?

Unless you do some rewiring, no matter how you connect them they will be in parallel and will present a 5.3 ohm load to the amp. The 8 ohm cabinet will get 2/3 of the amp's output (twice as much as the 16 ohm cab) and will probably be appreciably louder.

And if you want to use them this way, if your amp has a 4-ohm setting, use it.

Hhhmmm...it's sounding less and less like a good idea...

I don't know why you would say that unless your 8 ohm cabinet can't take 2/3 of the rated output of your amp (and you want to play BTTW) and/or your amp has to have a 8 ohm minimum load. Out front it won't be noticeable that one cab is louder than the other.

But use the 4 ohm outputs?

And how do I know if my amp requires 8 ohm minimum?

This is for recording, by the way. Not live use.

double track, my friend.

Does the amp have a switch to select the ohms?

as long as your amp can handle a 4 OHM load it will be safe to use

i dont think I would chance it using an amp that is only rated for an 8 OHM load.

it will tell you on the back of the amp what it is rated for

and for recording purposes you will only need an 8 ohm speaker

are you micking the amp or are you using your AUX out?
Aux out is the best way to go. IMO

Your combined load will be less than 8 ohms, so you need to set it for 4 ohms.

Why on earth would you need two cabinets to record?

Well, the Peavey JSX cabinet (16 Ohm) that the other guitarist is wanting to try out has a mic modeled direct out. Personally, I don't want to use it. BUT, I promised that we would TRY it just to appease him. I know it won't sound as good. I was looking for a way to record them both at the same time so I wouldn't have to do two takes, but it's not that big of a deal to switch the cabs over and play the take again.

I just wanted to be able to A/B the two quicker so I could prove my point whilst wasting as little time as possible.
