when doing pass through wiring should i worry about ohms or anything like that?

@evillemonkey -- Short answer is you should refer to the owner's manuals for both speakers and amplifier if possible - if you don't have manuals you may be able to find them online. Not knowing what speakers/amp you are using, or if speakers are powered, I can't answer. If the speakers are powered, generally you have less to be concerned with, but if unpowered you need to know minimum ohms your amp can handle. Note the pass-through jack is generally wired parallel and reduces impedence.

@evillemonkey -- not much space to write here - the video has hopefully given you a good general understanding of interconnections so you can understand terminologies and understand what specifics apply to your particular gear. I highly recommend having the manuals to refer to, for both speakers and amp, and your question pertains to both. All situations will be somewhat unique, as gear has different specifications. 2 8-ohm speakers in parallel is generally ok. Beyond that gets more tricky.

I would worry about ohms. I agree should always check the ohms of the speakers and the ohms on the power amp. That its so important. Also check the wattage your speakers can handle! you dont want to blow them up! Just remember this 2 8 ohms speakers hook up in parallel will lower the resistance to 4 ohms. So keep a close eye on that.

@whamuniversal ok thanks for the info and videos. I will look up the manuals, but you answered most of my question already. I'm using 2 8ohms (as mains) and wanted to also use a third, possibly fourth as monitors (non parallel)all speakers non powered. I will look up the power mixer manual now, thanks again.
