I'd love to swap my amp out for something else, but doing so with the Logic 7 system is a lot more difficult as I would lose my center speaker, and the connection from the head unit to the amp is fiber optic and already split for 7 channel audio. The amp powers the subs as well as the midbass/mids/highs.
I don't know the specs of the stock Logic7 amp and which subwoofers would pair well with it.
