From everything I ever heard as well...doubling of power = 3db gain...doubling the # of subs = 3db gain. This is on "paper" keep in mind..many other factors can effect output as well.

Another tidbid....10db gain = twice as loud.....so you can see as the number of subs and amount of power go up..it gets exponentially more difficult to achieve gains.

A reason to respect SPL winners...it wasn't luck if they are consistantly winning.

azn maybe  you should actually read my 1st post

all the way thru before making coments --

Im only trying to help --no need for wise remarks

You're getting warmer..however you still won't be utilizing the most power if you stick with the DVC4's and the pair of 2ohm stable amps.

If you use series/parallel/parallel you have a final load of 2.66 ohms....you want a minimum of 4ohms to bridge those amps or expect overheating. (remember the 2ohm rating is stereo...not bridged mono)

If you use parallel/series/parallel you will be at 6ohms ..this would work safely but if you are really looking for the most output from those amps you should be at 4ohm final load per bridged amp.
