Kyle, you may wanna read up on stereos before you jump into it...
all the sub does is bass.
i have my RF 4x6" pos speakers running on 200 watts. the keep up really well with my L7 at 1000watts, but if i ever wanted to give my sub more then 1000watts i would need to upgrade to some real speakers and add some more power.
do you know what you want your stereo to sound like? what kinda music do you listen to? do you want to feel the music only, do you what to have ear piercing vocals, combination of both?
dont build your system based on name brands per-say, do it based on the results they will yield.
