Hello everyone! I had an Icon 15 in a ported enclosure in my old ride and loved it. I would have loved to have had it in it's optimum sized ported box to see what it could really do, but the 3.75 cubes tuned to 34hz sounded kick ass anyway and got nice and loud. I had it powered by a 1200 watt JBL amp. The car I have now unfortunately can't fit the the Icon 15 enclosure height wise. I was wondering if an Xcon 12 in it's optimum sized ported enclosure tuned to 33 - 34hz powered by a SAZ-1500D V.2 could get as loud as my previous Icon 15 due to more motor strength?

There are more factors in terms of output then motor strength. You will be giving up cone size, and the power difference is probably not going to noticeable. Now heads up, the same size Xcon vs. Icon, the Xcon should be louder. But I have not tested heads up a smaller Xcon with a few more watts compared to a larger Icon.

also going to depend on the size of the vehicle you had vs the new one. if you had a single 15 in a tahoe, then you're going to do a single 12 in a crx, the 12 will definitely be louder do to pressurizing less air space. thats a very big swap size wise in vehicles just as a reference. i had a 15 in a small car ported, now i have a minivan and im doing a single 18 ported, im curious how it will sound compared to my old setup but really, as long as it sounds good ill be happy. probably be the same with yourself....
