500
250
125
62.5

Those numbers are all assuming the TOTAL LOAD is the same in all of the scenarios. I took this to be the case, as you were specifying a total output of 500 watts.

You understood what I was getting at perfectly, and thanks for confirming what I thought I already knew. I am going to be running B. That was my intent from the beginning, just confirming I understand the concept.

Pioneer GM-5100t Amp - Also have a 15+ year old Lanzar OptiDrivePlus 50 that pushes the subs harder, but can find no info on other than 25Wx2@4 LOL, has to be so under-rated it's not funny.

RF P212S8 - Subs

I am trying to match everything to maximize thier potential, that is why I am asking.
The amp should be putting out (bridged to 2 subs@ 4 ohm) 380Wx1rms/760Wx1max
That should be about perfect for the 200Wrms/400Wmax subs. They should each see 190Wrms/380Wmax.
