i wouldnt go with the comps. really a waste of time. at 150rms a peice its not really worth it. that would come out to like 600 dollars. i would do like 4 15s or something. but if your set on tthe comps i sasy wire 4 svc 8 ohms down to 1 ohm and push them with about 600 rms.
bassicall do 3 sets of 4 on three different amps.
