Can you stop saying that? The better sub will always be better on double rms of half of it. You are not stressing the bigger sub so it will last longer. By your logic a kicker comp on 500 watts will outdo a SA on the same 500 watts. That's not going to happen.
by your logic an ssa zcon on 500 watts should louder than an SA on 600 watts. Not happening. barely tickles bro.
Have you ever tried it? I can tell you my 95s got pretty loud on 500 a sub
last week I installed a type R for a buddy and put it in my old SSA Zcon box and have it on a crappy kenwood that does 500 watts at 4 ohms. 3.25 cubic feet box tuned to 33hz optimal recommended design built off of SSA. Its way louder than the zcon at 4 ohms on my brx 2400 during my break in period. The zcon only came alive after dropping down to 1 ohm and i was not even getting close to full xmax. For loudness a fully fed sub is better then a tickled sub.
just get any D2 ohm woofer that isn't rated passed 1250 and my amp is golden for it. (for optimum performance that is) you can always turn the gain down and put out less power but you can't make more power than capable.
A 15? If it's anything like its Fi brothers 3.25 is choking it. As for my personal experience having a pair of 12s do a 143 at 36hz on 1000 watts I'm sticking to my opinion.
12 man 12!!!! Its a super high output efficient box, had plenty of subs that got loud in it like a custom mtx 9500, c2 threatcon, the 12 w4 (on 50 watts reciever power) and the type r.
