Urgent speaker wiring question (Peavey Classic 30)

[gibsgstd1999]

So, I unhooked the internal speaker to hook an external cab up, and now I forget what wire is positive and what wire is negative for the internal speaker. Is blue negative and yellow positive? Is it this way in all amps? I just don't want to risk damaging the amp/speaker. What color wire is normally positive?

 

Thanks.

No idea with those colors. E-mail a tech or have someone here who has one,take a look.

blue and yellow?

 

that's odd.

[Boogs]

yellow = positive

 

blue = negative

Thanks, appreciate it! You're positive about this, right?

Wait a minute. Don't you own a Peavey Classic 30? What color are your wires?

Try it both ways. The way that gives you more attack is the correct way.

Please,if you don't know,don't answer. One speaker is never out of phase.

Hook up a 9 volt battery to the speaker leads with blue on the -post and yellow on the +. If the speaker cone protrudes, you have the correct scheme. If the cone inverts, then blue is positive.

I believe it is the leads that are a mystery,not the actual driver.

Just checked my Classic 30, Boogs is correct.

 

Yellow = positive

Blue = negative

Simple. Take a voltmeter. Connect one of the speaker wires(A) to a speaker. Connect one lead to the loose wire (B) and the other to the opposite terminal on the speaker. Play a single repeat note on your plugged in guitar. Now do the same with wire B connected and your meter running from (A) to a terminal on the speaker.  Play the note. The one that gives you a higher number is the positive. Doing this puts your meter in the circuit. Having it connect the negative side to the speaker puts it after the speaker in the circuit. The speakers resistance lessens the current you get.
