xXsquintyeyesXx Posted August 12, 2011 Report Share Posted August 12, 2011 Ive heard that if you don't have a ton of space to build a huge enclosure in your vehicle then you can put some kin of material in the box and it simulates more airspace. Ive seen someone do it around here. They had three fifteen inch memphis mojos in the trunk of a car and since they didn't have enough airspace they put something that looked like insulation in the box and they said it simulated more airspace so the subs would play like there was the correct amount of airspace in it. I never got to here it so I don't know if it really worked. So I was just wondering if anyone has heard of anything like this and if so is it a good or bad idea Link to comment Share on other sites More sharing options...

jmilch Posted August 12, 2011 Report Share Posted August 12, 2011 You can buy it at walmart... its used for pillows. Nothing special, its called polyfill. It does help a bit for the response. But honestly, reducing the number of subs and building a better box would be alot louder. But people say around 3/4 lb per cube for small sealed enclosures.
