home made 3 way passive crossover

Ok, I'm sure this has been gone over before, I read about 3 articles on various sites about this, so kinda have my head somewhat wrapped around it.  But could somebody please refer me to post on here or anywhere to actually see a system put to this?  I still have some questions, like.... it seems with a 2 channel amp, bridged, I could have 4 tweeters, 4 midranges and 2 subs?  With a 4 channel amp, add 2 more subs!!  Is this possible, or am I missing something?  And where can I basically..... sigh, hate to say it, but "steal" some one's simple already bought design and mess around with it?

You're talking about a tri-mode setup.  This was fairly common in the 90's for low-budget installations, but is not a setup I recommend except when absoltely necessary.  Amps are just too cheap these days to set up a marginal system like that.  But if you must, look for a stereo amp that says it is "tri-mode capable" and make sure you are using 8-ohm or higher speakers all around.

Ok, that makes sense, it was in the 90's, Ok, cool, that's pretty much the answer I was looking for, because the tri mode thing kinda threw me off, and I suppose they would have to be fairly high ohms.  OK, thanks!!
