Thanks, guys-- that'll give me a place to start.

So what should I set my low pass at for my FI Q10 that I am getting ready to install? Its a D1, if that matters and the woofers I am running are 6.5" Rainbow Kicks.

In the 350Z community Zenclosures are almost legendary for their form and fitament. They have several boxes that fit under the unique 350Z rear strut: Zenclosures on eBay I'm handy enough with MDF that I think I could throw together a pretty solid sub box, but I don't know that I can custom build a box that would fit better than the Zenclosure!

I have a couple of questions regarding the 10" FI Q. Will a JL Audio 500/1 be enough to get decent SQ out of the D1 sub, wired for 2 Ohms? I'm looking for nice, tight bass, rather than real loud. What's the optimum sealed box size for this sub? I'm looking at two pre-made boxes for my 350Z, one is .75 cubic feet (Large understrut 350Z box), the other is .43 cubic feet (Small 350Z box --both measured before the displacement of the FIQ10, which is .12 ft^3, according to the specs page. That's approx 6.3 ft^3 for the larger understrut box (I can add some add some wood to the inside to get that down under .6 ft^3), or .31 ft^3 for the smaller box -- which seems pretty tiny for the Q10. Suggestions?
