Slinky Posted February 5, 2007 Report Share Posted February 5, 2007 that should be big enough. 43 hz sounds more competition oriented. is this a comp vehicle or daily cause 43 is a tad high for daily.

Slinky Posted February 5, 2007 Report Share Posted February 5, 2007 interchangeable ports would def be a good idea in your case.

Slinky Posted February 5, 2007 Report Share Posted February 5, 2007 if you are in competion, tuning up would be louder, but for daily 30-40 hz is good.
