I’ve been here but inactive for some time now getting back into the stereo scene. Last system was 4 alpine type r 12s 2 rf prime 1200.1d Amps 2 offbrand agm 74ah batteries along with a optima red top in my old srt8 charger. Now I have a second gen Durango and no longer am concerned with weight reduction I’m trying to put a small but good setup in and am leaning towards the Skar rp 1200.1 d due to the fact I was considering the rp1500.1d but it falls short on the dyno where the 1200.1d really shines and does well over rated power. Subs are undecided as of now was thinking power Acoustik gothic 12s massive audio gtx 12s or just going all Skar with either sdr’s Or svr’s. 

Dyno doesn't measure anything for crap.  Take it with a grain of salt.  Measurement without stated uncertainty is NOT a measurement.

I would also run like hell from anything Skar.  Owner is a crook and products over hyped.
