Granted I will do the build but will pay for the plans. I can design regular ported boxes but never tried a 4th or 6th. Subs will be ab xfl 10's off 1 k each. Car is a 97 civic coupe I can use all the trunk space if needed (all I'm sure) port will be forward firing and sealed off from the trunk. I'm not going to compete but would like to see a good number when I do go to shows. I mostly listen to old school (90's ) hip hop. I do love some 90's Rock also but my front stage will take care of most of that. I know the xfl's are quite stiff and that's why I was contemplating a 6th.
