Joe X Posted February 20, 2023 Report Share Posted February 20, 2023 I would need some infos from you, 1) The height of your seat line and window line. 2) What performance you expect, low, loud etc, what music you play. 3) Pics of your sub manual showing t/s parameters and manufacturer recommendations as I didn't find anything on their site.

Joe X Posted February 21, 2023 Report Share Posted February 21, 2023 OK so do they list box recommendations for your sub? if so post them. With the parameters above I estimate 3.5 net @32-34Hz 60 square inches of port area for each sub, but I would like to see what they say, the manufacturer can also use auditioning for setting their recommendations so it's always useful information.

HermanS Posted February 21, 2023 Author Report Share Posted February 21, 2023 They do not list box recommendations anywhere in the manual or even online, Link to comment Share on other sites More sharing options...

Well if you compete and depending on the class that you compete in, some classes have a rule that the box must be under the window line otherwise it is considered a wall. The window line rule is based off the front door window line however which can sometimes be a different height than rear windows. Also some people just don't want a tall box sticking up so high that is in plan view for everyone to see, plus in all honesty it can be rather ugly in some cases. Some people with suv's also like to be able to put the cargo cover over the box to hide it if your vehicle has one of those. Link to comment Share on other sites More sharing options...
