Contour Enthusiasts Group Archives Forums Modifications Audio ok - BP1001 or BP1002?

so i'm getting that USA-6300 AMP 6 channels -
RMS @ 4 Ohms @ 12.9v input 50W x 4CH + 150x1 or 65x2
RMS @ 2 Ohms @12.9v input 75W x 4CH + 300x1 or 80x2

so should i get the BP1001 or BP1002 for this application? i'm guessing that if i just bridge the two channels into the BP1001 then i'll just have 300W to that... otherwise running 2 separate channels to the BP1002 (so 80W/VC) - which is better? i'd assume the prior...
