There is no reason why you can't make this sub work well for a car audio application. It just requires a little different design parameters than for home audio use.

As far as WinISD goes, make you sure you get the newest version. For some unknown and frustrating reason they don't have a link to it on their website, but you can download it here: http://www.linearteam.org/download/winisd-07x.exe

Entering in the sub parameters is the hardest part of using WinISD. Here is a description on how to do it best:

1. Enter Mms and Cms

This gives fs. If either is not available, then enter fs and other parameter.

2. Enter Sd, Bl and Re

Now, you should get all but Qms (and Qts), Vas. Please note that Vas may not match exactly what is specified by manufacturer, because exact value of Vas depends on environmental parameters. See FAQ.

3. Enter Rms or Qms.

Either one will do, although I tend to prefer Qms over Rms, because it can usually be measured in driver measurement procedures.

4. Enter Hc, Hg and Pe.

If Hc or Hg or either is available, then enter Xmax and optionally either Hc or Hg if available.

If you run into any other issues with WinISD, just let us know. I've used it enough that I can totally make WinISD my bitch now.

I don't know if you were referring to me or JoeX about sending a PM, but I did not get it.
