2 10w3v3 or 2 SI BM IV

Guys,
appreciate any input you have on this topic. I have a 2012 Crew Cab GMC Sierra and will be having a local shop put in the components I select. I have been running two JL 10w3v3-4s in a 2-ohm configuration for the last few years. They were in an F150 crew cab with a custom sealed enclosure. Overall, really happy with the sound but am possibly looking for a change. I currently have an old school RF 501bd that was running the two tens. Really looking forward to trying the SAX-1200D from Sundown when it comes out. My question is this...I mostly listen to rock music with some get down bass every now and then. Curious how the two 12s from Stereo Integrity would compare to 2 JL 10w3 subs. Volume wise and hitting low notes. We can achieve about .75^ft per sub I believe, maybe slightly more. Driving them with the Sundown amp, curious how these two sets of subs would compare.

Just for reference, Front stage will be MMATS Pro Audio 6.5 components with MMATS Pro Audio Coax in the rear. Those will be driven with the Alpine PDX-F4.

Thanks in advance!
Jay.
