  3. Box Design Question

    i have one zapco 3k and two lightning audio 3 ks i found i was getting better numbers with the lightning audio amps. but i think thats because i didnt have enough power for the zapco. my aa subs are dual 2 ohm and my hybrids are dual 1 Thanks!!
  4. Box Design Question

    trying to build my own battery as i cannot afford anything else at the moment. each cell is 4v and 8.0 ah
  5. Box Design Question

    so after i got the hybrids in my vehvile and the zapco 3k i was down to 145.5. so i swapped my old stuff back in and got it up to a 148.3. now im wodering if my older lightening audio amps need less power then my zapco and thats why i was getting smaller numbers? but anyways i wanted to see if people in here saw a increse or decrese from deadening the roof of their vehicles? i got people to sit on my roof before and saw now gains or no losses so i dont know if itd be worth deadening it.

  7. hole shit crazy build man! thanks for sharing
  8. Box for 2 15" Earthquake Subzero's

    yea it definitely helps! and your totally right i didnt consider port ratio at all. i did a little bit of reading on it and lower seems to be the popular choice. thanks for the info man! i always love learning new things on how to make my next build better
  9. Box for 2 15" Earthquake Subzero's

    so i changed the port to 5"x20" (which if im doing it correctly) should be a 4:1 ratio? effective length is 24.75" I looked up port ratio and Triticum Agricolam mentioned its better to get it as close to square as possible, am i correct?
  10. Box for 2 15" Earthquake Subzero's

    so if i made it 5"x20" would that be a 4:1?
  11. Box for 2 15" Earthquake Subzero's

    so i increased the width to 38" and the height is still 3" the effective length is 21.75" Do you think this would work? also i had a quick look around for torres but im on a mac
  12. Box for 2 15" Earthquake Subzero's

    holy fuck! thanks man! do you think i should use this http://www.mobileinformationlabs.com/HowTo-1Woofer-Box-CAL Port lenth 1.htm for calculating my port length? also would 115.5 be too much port area?
  13. Box for 2 15" Earthquake Subzero's

    Interior dimensions are 3"x20"x14.5" leaving 4.5" between it and the rear wall for end correction and one soundstream t1.6000dl claims to do 2500 into 1 ohm
  14. I'm looking to put 2 15's in a 98 tahoe and i have this design i just wanted to see what people think of it or have any suggestions for things i should do different. i've never done a window before or a square port so any tips would be greatly appreciated! Volume is 6 cubes tuned to 33hz
  15. Really great post! thanks for sharing everything you learned i really wanna try fiberglassing and this gave me some motivation!
