I'm using a JBL 1041 that was originally in my old Honda. I've got it in a 1.75ft tuned @ 24hz. I'm using a 150 watt plate amp that is on clearance at MCM. It took a lot of modeling to come up with a design I could live with since this sub was definitely optimized for automotive use. But it paid off, this sub is awesome! It mostly sees HT use but it sounds almost as good with music. Musically speaking I would have went with a sealed box but I doubt Jurassic Park or U-571 would have been the same!
