Yeah like I said I am running those pioneers in my Subaru. I just have them sealed, so I'm sure I could pull some more out of them, but these big motor big xmax slims are another level. I honestly like the pioneers. Clean, crisp, and at times fairly punchy low end. Pretty great SQ, especially sealed. I would throw them in a ported box, but my wife now drives that car and she likes the subs just how they are (very much not a bass head). The Sundown SD-4 has me interested as well. It does have more mounting depth the the 10tw3, But it has good xmax. But, when I was modeling the two side by side the JL liked my enclosure better. And since the sundown is already $300 each, I figured what's an extra 80$ for the JL (actually an extra 40$, I bought
Crutchfield open boxes)
