cool.. I was thinking... could I wire the 2 sets of components together on channel 1 & 2, then wire the new set of tweeters on channel 3 & 4?

 

Yes. You'll be better off with one set of components of each pair of channels and then the tweeters running alongside the one set.

 

Just to clarify, I should run both sets of components as normal (channel 1-2-3-4), and wire in the tweeters (& crossovers) on say channel 1-2?

 

That would be how I would do it.

 

good to know... I figured that if i were to wire the component sets on channel 1-2 or 3-4 and the tweeters on the other 2 channels, i'd be able to control the volume of them seperately from the components.. daymn lol
