Does anyone know how to add an extension out to an amp?

[Moustache_Bash]

I have a Peavey Special combo that works at 4 ohms. I want to have an extension out on it so that I can run an extra cabinet as well as the internal speaker, so probably make the internal 8 ohms (I'll get a new speaker) and put the extension (8 ohm again) in parallel. Is there a simple way of doing this?

If the amp runs at 4 ohms, and you replace the internal speaker with an 8 ohm, it's really easy.

Most speakers have 2 tabs on both the positive and negative terminals. Just use these two extra terminals as 'outputs' to a 1/4" jack, + to the tip, - to the sleeve (parallel like you said). If you have slide on connectors you don't even need to solder (although I would to be safe). Find some way or somewhere to mount the extra jack and you're in biznezz.

Stay away from drilling the chassis, put a hole in the cabinet somewhere and make a small metal plate to mount the jack. the bottom of a broken pedal works well.

Holy shit, I don't know why I complicated that in my mind. That IS super easy. Thanks, man! Super stoked on this idea.

Hey, anybody know what the name of the terminals are that slide over the speaker? I'm guessing it would be the male part.

I think they are called crimpets

You're right, though, crimps. I was looking up sleeve terminals, but that was a no go. Thanks, SS.

hahahahahahah yeahhh I knew I was close!

The technical name is "female spade terminal".

you can do this of course so long as ur not going to overpower the internal speaker. I assume that is not a problem but in the general case there will be equal power delivered to the extra cab and the internal speaker. Its kind of like hooking up a 1x12 and a 4x12 to a marshall head. The two cabs have the same impedance so half the power is applied to the 4x12, and half the power is applied to the 1x12/

I was thinking of using an Eminence Wizard for this. The speaker is rated for 75 watts, and the amp is 95 watts at 8 ohms. Problem?

[new05002]

so long as you didnt defeat the internal speaker, ud be okay

[Moustache_Bash]

Right for impedance purposes. As far as wattage handling, though, 95 into 75 shouldn't cause me any grief?

[new05002]

oh well if that 75W speaker is the only thing u going to be driving that power into, you risk blowing the speaker. I assumed that you were using more than just 1 speaker.

If you use both of them, the power would be shared between the 2 speakers or N number of speakers in the entire system.
