Joe X Posted September 30, 2014 Report Share Posted September 30, 2014 So here is a suggestion, trunk car, power: to sub(s) rated, amp subsonic filter to 28Hz, minimum port clearance 5", figure is just an assembly guide:NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside. 45s if you wish to do them, like this: Link to comment Share on other sites More sharing options...

MrSkippyJ Posted October 3, 2014 Report Share Posted October 3, 2014 I wouldn't worry about 45s. Your net volume will increase marginally but nothing worth worrying about.

RainStryke Posted October 4, 2014 Report Share Posted October 4, 2014 The 45's are not for increasing volume, it's to keep the air flow fluid. Link to comment Share on other sites More sharing options...
