  1. also can you take your plasic cover off the mag? what is the mounting depth after that?
  2. what is this box going into? a suv or truck or what?
  3. let me get my mouse and i will open cad....
  4. then i would build it to the fs of 33. im sure it will still sound great with a lil high qts. do you need me to draw you a box or can you get it from the port and length?
  5. yea the only true way is trial and error. i really think either way it will sound amazing for 2 p2 10s
  6. easy way to figure out ohm loads for bigginers is go to rockford fosgates website. they got an ohm calculator. if they dont have a choice for 6 4 ohm subs then do 3 dual voice coil 4 ohm subs. its the same thing.
  7. "when building a t-line for a sub based on Fs, you need to keep in mind the speakers Qts, and Qms, they should be low for SQ, Qts of .40 and lower, and Qms of 7 and lower will work great. Qts is speakers total quality in Ratio to its electrical, and mechanical characteristics, Qms is the Mechanical ratio. If you want to run a sub for more of a spl use, its better to run a woofer off of a Bass EQ/ Amp bass boost circuit/ Deck boost. But it cant be mixed frequecies, like a deck with a 60hz boost, and a amp with 40hz boost, you need to cancel 1 freq out, or level the 2 freq's (there will be cancelation, and the sub will sound like its being pushed to hard-boost for tline have to be close to the quarter wave of the box as possible) This allows you to use a shorter tline length, in comparison to the speakers natural Fs quarter wave length. But Tlines, with Low Q woofers, like .30 and lower, you will be amazed how low the subs will play, lower than the boxes quarter wave length- almost down to the next octave- Cleanly. So, your looking at about 20hz almost as loud as the subs 40hz peak tunning. (depending on cabin resonace of vehicle ofcourse)" From foreverbumpin's tot. if you use a deck or amp freq boost it would work slightly better with your subs. but either way it will sound good. do you want more of an spl or more deep bass?
  8. ok for the math part. (speed of sound/fs)/4= port length 1130/33=34.24ft 34.24ft/4=8.56 ft for the quarter wave now the port area is the sd of your sub (effective cone area) your sd is 53 times 2 (for two subs) is 106 sq in's of port. so the basics are you need a 106sq in port 8.56 ft long
  9. with a qts and qms of .5 is not the greatest ive read that you wanna stay around .3 or lower. my re's have a .35 i think and they sound great. .5 is up there a bit but im sure it will still sound pretty good.
  10. http://www.mecacaraudio.com/2009rulebook.pdf
  11. another question, do they just look at the fuse rating that you have right before your amp? or the fuse under the hood (if you have one)?
  12. jk found the rule book
  13. In Amature street or in street is there a limit on the bats you can use? or is it just the fuse rating you have right before your amp with cone area to make up the class?
