bit of a live sound question. been reading a bit on series, parallel, and series parallel wiring. could i effectively run (4) 8ohm monitor wedges off one channel at 4ohms by making up special cables? positive out of the amp into wedge 1 and 2, negative out of 1 and 2 into positive wedge 3 and 4, negative out of 3 and 4 back to negative on amp.... would this work? we have a 2 channel amp and we are commonly running 4 wedges off one channel, and 2 on the other. we are going to burn the amp up soon....
 
The hassle to wire cables like that makes it not worth it, IMO. Not to mention that each wedge would get half the power it does now, and each monitor now has two cables attached to it, and they are all hooked together.
And either the cables or boxes or both will be unusable for regular use.
Serious pain in the ass.

What amp are you using? Is it rated for 2ohms per channel? If it hasn't blown up yet, what's the problem? :)
 
You could replace the drivers with 16 ohm and pad the horns.

Or buy another amp :D

it is a carvin something or other... i forget.. if you parallel 4 monitors, they would each have 2 cables attached anyway...

Paralleling 4 monitors can be done with 4 cables, 8 connections, and only one line to the amp.

Your idea means 6 cables, 10 connections, and 4 lines to the amp.

Mshilarious also had good suggestions.

Your idea is workable, just a pain. You'll have to rewire your boxes and make some special speaker cables.

For the money you spend on cables and time spent rewiring them and the boxes you could probably get some 16ohm drivers and power resistors for the tweeters, or come close to getting another amp.

Finding the model number and minimum impedance of your amp is the place to start. If it can handle 2ohm loads, it doesn't matter anyway.
