If i wire two subwoofer together for a certain ohm rating would the power handling of the two subs be combined or would they still be getting the max power of the amp to each sub?

so if i have two dual 4 ohm subwoofers wire together for 4 ohms and they are 200 watts rms and 400 max and the amp puts out 850 watts at 4 ohms would the amp be over powering the subs?

Tha amplifier's power is split... Wheter wired in series or parallel, each woofer gets 1/2 (in the case of 2), 1/3 (in the case of 3), and so on...

It all reminds me of something that Molière once said to Guy de Maupassant at a café in Vienna: "That's nice. You should write it down."

Is the amp putting out 850rms or 850max at 4ohm? how many channels is it?

It doesn't matter. The question was "is the power handling of the woofers combined, and is the power output of the amp split?"

if you have them wired for a 4 ohm final load then they are getting 425 a piece.

if you tune the amp properly and take care of the woofers they will last a while when over powered. Obviously build quality will be a factor, but many systems have an 'over powered' amp system and go for years.
