Wiring a Cabinet?? Look here

unconventional · 06-06-2008, 09:05 AM

Seems to be some threads with hints of this inside, so I decided to create one rather then derail others threads which usually results in no answers for me.

So here it is.

Is this a good way to wire a 4x12?

I have a bunch of 8ohm speakers coming.

I'm also told that you can test ohms with a voltmeter, is this correct and what is the proper procedure?

Thanks.

idk about a "volt meter" but a multimeter will do just fine, you can them from $5-$70, very handy for a guitarist, they are really simple to use, just turn the dial thing to ohms

Yeah I have a fluke 289, but don't really know much about it. Stole it and a dewalt chopsaw, cordless drill and several other items from the builder of my house that wouldn't fix a problem

Good idea, stickied

budda · 06-07-2008, 01:13 AM

does the 412 you're wiring have speakers? do you have another 412 to refer to?

i just simply kept the colours the same when I replaced the speakers, made life really easy lol.

Ideal makes good stuff

Fluke is top of the ....ing line but expensive.

Set your multimeter to ohms plug in your speaker cable to the cabinet, and touch the black probe to the sleeve and the red probe to the tip of the other end your speaker cable plug. This will give you a readings of ~14ohm for a 16ohm cab, 6-7ohm for an 8 ohm cab, and 2-3 ohm for a 4ohm load.

Thanks for that. I was thinking my meter was off or something.

I wired up my 4-12" a different way. The old PV cab I own had really small gauge wires in it 24 gauge I think. When I went to 16 ohm Texas heats, I wired the cab with an extension cord (rated at wall current 2700 watts) into2-8ohm branches. The cab has no ohms switching or one input operation, but I made 2 custom y cables to either half or double (the "fourOhmulator" and the SixteenOhmulator respectively.) these are nothing more than a speaker cable cut in half and wired onto an input jack, series or parallel. The bigger hand wired cab is WAY more efficient and clearer sounding than it ever was before. Something to think about.

Found this on the Eminence website:

Wiring Configuration for 2 Speakers in Parallel

Two 4 ohm speakers = 2 ohm load
Two 8 ohm speakers = 4 ohm load
Two 16 ohm speakers = 8 ohm load

Wiring Configuration for 2 Speakers in Series

Two 2 ohm speakers = 4 ohm load
Two 4 ohm speakers = 8 ohm load
Two 8 ohm speakers = 16 ohm load

Wiring Configuration for 4 Speakers in Parallel

Four 8 ohm speakers = 2 ohm load
Four 16 ohm speakers = 4 ohm load
Four 32 ohm speakers = 8 ohm load

Wiring Configuration for 4 Speakers in Series/Parallel

Four 4 ohm speakers = 4 ohm load
Four 8 ohm speakers = 8 ohm load
Four 16 ohm speakers = 16 ohm load

Okay, what if I wanted to wire up my Vader cab in stereo with switching jacks?

Since the Vader only has two jacks on it's panel is there a way to wire it so that if I have one cable plugged into one jack it will be mono, but if both jacks have a cable present it will be stereo?

I wanna use both sides of my 50/50

Zepp88 · 09-06-2008, 03:45 AM

After some research, I found this site.

Cool shit.

Zepp88 · 09-06-2008, 04:17 AM

Nice, also, they have a nice explanation of how to count ohms.

sami · 09-29-2008, 02:44 PM

How about mixing 2 cabs with different ohms? Here's an easy formula to remember:

Take the two cabs, multiply them for the 1st integer.
Add the two cabs together for the 2nd integer.
Then divide the 1st integer by the 2nd to get the result.

(cab1 x cab2) / (cab1 + cab2) = final ohmage

example:

cab1 is 16 ohms. cab2 is 8 ohms.

so

16 x 8 = 128
16 + 8 = 24

128 divided by 24 = 5.33333 ohms.

djcheesmo · 11-03-2008, 04:38 PM

2x8 ohms speakers wired in parallel = 4 ohms , wired in series = 16 ohms..
doing this twice for 4 speakers brigs it back to 8 ohms...using a 12 guage wire
over 16 or even 14 will for sure be helpfull .not sure if one can hear the actual difference the guage makes?? however the amp will know...

jllozano · 11-05-2008, 09:32 PM

which is the correct configuration out of these for a vader 4x12.....?any help would be appreciated....

FoxZero · 01-23-2009, 11:56 PM

This is a cool thread, I wish I still had my link from a while back.

Anyways I got a Vader 2x15 with two input jacks. I want to daisy chain my cabs, so does anyone know if it is possible for me to convert one of the input jacks into an output?

headnuts · 08-20-2009, 05:30 PM

hey im trying to put some new speakers in an older pv xxl cab, it has blue marvel 16 ohm speakers and i just got 2 V30's and 2 greenbacks that are both 8 ohm, i believe that the factory wiring is wired parallel for the 16 ohms. can i just swap out the speakers for the new ones?

Sy-Furr · 09-05-2009, 01:27 AM

Here is the Marshall and Randall and many others type of wiring.

This is for a 4Ω/16Ω mono and a 8Ω stereo setup.

I drew this myself so please double check me!

Wow, this thread answered a handful of questions I had. Thanks!
