Sorry to drag this post on,but am i right in thinking that passives will do the job POST amp and an active does it PRE amp? If thats the case,can i use a 2 way passive,post amp,and use 1 way to feed the 2 subs,then the other way to feed the mid/tweeters,as the existing crossovers on the mids are OK?? Then rely on that to split the sound to the mids & tweeters?
