OK... I have FOUR 6-3/4 pioneer speaker, and they are amped by a 4x40w alpine.... I wanna get a component system, 2 sets of 6-1/2 woofers and tweeters...and then the same thing in the back ......

the confusing part for me is the 2nd speaker, the tweeter... do I need another channel or will my 4 channel alpine amp do the job?

basically my question is can I use my 4 channel to power 2 sets of components (8 speakers), and if I can, how would I wire it up given I will just be swapping out the speakers .... please respond, thank you

 

The xover will be in place for each position IE your comps will come with a component crossover, mid woofer, and tweeter. The xover has an input and then breaks down the signal to each speaker. You will have four xovers for two component sets.
