Subs set up whats better?

[Deech]

I was just wondering, I have two powered subs running from my receiver. This is how i have them set up, I have one sub out plug on my receiver which runs to my first sub into the sub in plug, then the sub has a sub out plug (to run more subs) on it which I run to the other sub. My question is would it be better if from the sub out plug on my receiver I plug in a splitter and then run each sub off of that? would that be a better set up then running one sub from the other sub? Thanks
