is 100 watt enough for 90 rms
 

got an rf 8a4 but now im looking into components and i see that the jbls and the infinity's ask for 90 rms? i know the rf is only gunna get like 75 rms {hopefully at 4 ohms} any one?

800a4? 75watts x4 @4OHM is the 600a4.

yes they itll be enough. RF's amps are a lil underated according to their birthsheets. or at least the older model.

i was looking at
kicker
infintiy
focal
jbl

heard any of these

my questions about these
sound ...
the focals look cheep matirial
i keep hearing that the infinitys need booku power to sound good and my brother whos running a jl amp the 100x4+something to 1
says they have terrable bass reproduction he has the kappas
i was gunna get kappas or reference i dont remeber off the top of my head which ones better

thanks

i dont think focal is in the same class as the rest of the brands you posted....i really doubt they are of cheap material.

kappas are higher modeled than reference.

lower or higher class

focals?

definitly higher.

oh i was looking at ebay and there the same prices as the infinity perfects

kicker
infintiy
jbl
and alpine
heard any of these
