Broke_Audio_Addict Posted May 23, 2015 Report Share Posted May 23, 2015 What amp are you powering your sub with? That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

There is about 2 feet open space in the trunk. I tried to slide the subwoofer closer to the trunk and it did not help. Link to comment Share on other sites More sharing options...

Thanks for the reply, just redid the port with 4 inch clearence from the wall. It still hits the notes the same. Should i add another 4 inch port? If so does location matter for a second port? When my box was sealed and the lows hit it would look like my doors were slowely flexing open. Now the bass feels like its trying to shock my brain Link to comment Share on other sites More sharing options...
Triticum Agricolam Posted May 25, 2015 Report Share Posted May 25, 2015 If you add a second port it will have to be longer than the one thats in there now, and you will have to lengthen your original port.
