4 speakers vs 8 speakers

[pennyracer]

someone help me understand this thread ? so are we talking 2 way coaxil speakers or two seperates for highes ? it seems from what ive looked into the power rating on a two way or three way speakers are not super high so my thaught was ad a few more speakers to break the power up so you not working the hell out of two speakers rather than three speakers or more im not here to argue i like to just get the info so i understand things better for some who knows what works and maybe have done it also i have looked up some spendy speaker sets for thousands of dollors and they all seem to peak out at 200 rms thats seems way low maybe im missing something here im still trying to decide how money to invest in the rear highes on my liftback i only run 5 1/4" 2 way arc audio speakers for rear fill right now i will match brands so it will have to be focal speakers just not sure if i will take the time and money to go seperates or coaxil in the rears i am thing about running focal 8" two ways they sell and make a full speaker ecloser built whithin the real quarter panels just depends on the gain for for the time and money invested to do such a job
