AK bass Posted February 11, 2014 Report Share Posted February 11, 2014 because your window acts like a port when you lower the window i could be wrong though. so my car turns into one big 6th order? Kinda yes, if you have a sealed box would your car become a 4th order? I think about this sometimes, I can be wrong too. "The secret to creativity is knowing how to hide your sources."

Miguels Posted February 11, 2014 Report Share Posted February 11, 2014 i havent had bass for over a year so forgot how this works.. when you have someone in the passenger seat lower the driver window so the pressure hits them.. could be the other way around.. like i said forgot since i havent tried it much my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/ Link to comment Share on other sites More sharing options...

Wicks Posted February 11, 2014 Report Share Posted February 11, 2014 Your cabin is really a subwoofer box itself. Opening a window is in essence like porting a box. It relieves some back pressure on the subs and actually reduces the impedance your amp "see's". Therefore allowing your amp to output more power. Since the window acts like another port, it can also affect your overall tuning which could also explain why the sound is different.
