I have a couple of small wedge/pa cabs (10" & horn). I would like to put in an on/off switch for the tweeter. I occasionally use it for a bass monitor for the drummer when the band is stuffed in a corner, but the horn is very hissy. It sounds fine when using as a full range cab through the pa, but too noisy for just bass. It there an easy way to install a switch turn it on and off. I'm a total noob when it comes to speaker wiring so I would need to know what type of switch, and where to put it (+ or -). Thanks a million.
