okay so i want to build a bigger ported box for my 15" audio planet subs right now there just in a stock sealed enclosure and i have a couple of questions first
1. would doing this make my subs any louder or hit any harder?
2. the specs on the site says: freq.response 25hz-1khz
3. should i build my ports tuned to that or does it matter what i tune it too?
4. how do i build my ports for the specific frequency i want it to have
thank you im just a beginner
