Also a good choice but I wouldn't worry about powering two of the regular Shiva-Xs as they are pretty efficient. If there are 5 left, you should scoop two of them up! Also note that they list PMax and they are not as under rated power wise as many other car audio companies do (like the SEs which can take quite a bit more power than they're rated for). My DPL-10 can't handle much power over what it's rated at but also doesn't need it either. My friend's Tempest-X is the same way and he's running it with a 450w plate amp in a large ported enclosure. It gets loud, low, and sounds great but is not a power hog by any means.
