Jordan Thurston Posted May 26, 2015 Report Share Posted May 26, 2015 Hey guys I have 2 soundqubed hds312s in a ported box firing into the car and it's loud with the trunk closed but when I open my trunk it's way louder why would it be louder with the trunk open vs closed ?

Jordan Thurston Posted May 26, 2015 Author Report Share Posted May 26, 2015 Lol well it's a lot louder I mean crazy loud vs having the trunk shut I guess I'll just drive around with the trunk open Link to comment Share on other sites More sharing options...
_paralyzed_ Posted May 26, 2015 Report Share Posted May 26, 2015 something about sound waves not having enough distance to fully propagate in a closed environment or something...Try changing the orientation of the box. If it is firing forward, try having it fire backwards, or fire up, basically experiment until you have the best balance of loud inside and trunk closed.

_paralyzed_ Posted May 26, 2015 Report Share Posted May 26, 2015 Every car/box combination has an orientation that works best. You don't know what that orientation is until you experiment though. Link to comment Share on other sites More sharing options...
Jordan Thurston Posted May 26, 2015 Author Report Share Posted May 26, 2015 I know it's louder facing the subs towards the back but my trunk rattles really really bad so that's why I fired them inside the car maybe I'll have to just flip them around and figure out how to make my trunk not rattle Link to comment Share on other sites More sharing options...

thefourth Posted May 26, 2015 Report Share Posted May 26, 2015 How do I stop my trunk from rattling really bad I've tried everything it won't stop my bumper and everything rattles Sound deadener. Expanding foam. Thanks alaskanzx5 I might just do thatI can recone a sub myself. About a year ago I took 2 12" power acoustic mofos and made one sub. I took the magnet and the motor off of one and j b welded it to the other motor and magnet. I had to wind my own voice coil so it would work. After I was done hooked up to 2 boss 5000w amps. And shattered my back and all my side windows came to this thread to recommend soundqubed and ct sounds. OP goes with soundstream. oh lawd.

Jordan Thurston Posted May 26, 2015 Author Report Share Posted May 26, 2015 So just more sound deadener I don't really want expanding foam everywhere though maybe I can try just sliding the subs back in the trunk more but keep them facing forward Link to comment Share on other sites More sharing options...
_paralyzed_ Posted May 26, 2015 Report Share Posted May 26, 2015 Everything is a tradeoff. If you can't hear the trunk rattles inside the car, who cares if the trunk rattles? I'd rather have it loud inside the car and have the outside sound like it's falling apart than have no rattles and it less loud inside the car.But yeah, deadener and foam to stop rattles.
