    And that is according to circumstance, but for the most part, it still holds true. In a typical system the subwoofer and tower speakers get driven the hardest and you want to do your best to distribute the load for better thermal performance. The power supply of an amplifier is usually the limiting factor when it comes to power, particularly when all channels are driven simultaniously. So you don't want to place an inordinant load or unbalanced load on one component. And part of it is that if I have a multi-channel amplifier sharing a single power supply, I don't like to run the lowest allowable impedance across the board. The set-up of the Supra OEM Kenwood Excelon systems made every configuration mistake possible and shut down often, although it wasn't bad equipment, just bad execution, and it was correctable.

    I know this is a month late from the last post, but here is what I am running and it sounds great. 6 in boat 6.5 inch speakers running off the head unit. A dedicated 2 chnl amp for the 12 inch sub and a dedicated 4 chnl amp for the 4 tower speakers. Sounds great, even in the bow.

    I was impressed with the in cabins running off the head unit but thats in a service bay with the engine off... I will focus on the tower and sub first and go from there... time is going to be the main factor for me... my work is getting super busy
