  1. video of my race car on feb 7th 2009 at sunshine drag strip this is the kinda stuff i know a good amount about, stereos no so much but would love to learn more, this is just a standard bore 350, full bodied race car can run 7.20's in the 1/8 but we put about 250lbs in the car to run this 7.50 index heads up class just though yall might enjoy watching it as much as i do. It makes me happy ;)

    My love

  2. those ports would work. you could even use large PVC pipe if the diameter is the same. but dont be too disappointed if the output isnt what you expect. ported boxes tend to be a lil larger before port displacement and everything

    No i too 1 1/2 inches off it to compensate for the 3/4" on each side so its internal measurements, i like low bass but thats all it can really move air with is that really low bass like in the high 20 to 30hz range. but im gonna try to block off part of the box first and see how that sounds then if all else fails ill try the port cuz im not to worried about the box cuz its only gotta last till the taxes come back lol then im throwin another 12w7 in it and having a good friend of mine build me a 3.5ft3 ported box with a common chamber tuned to around 35hz so ill give yalls ideas a shot thanks for the help, noobs can always use it. :D

  3. I try to keep my enclosures within +/- 10% of the reccomended enclosure volume for sealed specs. I would think that because of the enclosure being over 1 cube larger than reccomemded that it is not playing to it's full potential and be extra "boomy" sounding.

    I would suggest that before you start cutting up the enclosure that you just temporaraly add some wood inside to reduce the air space and see what it does for you output. 1 cube is alot of space to fill up but it should give you a good idea as to what's up.

    Yea i was thinking about that just blocking off a portion of the box before i cut any off of ill try that and see how it works out

  4. So when i acquired my jl 12w7 my buddy had a box for it built so he gave me that with it when i traded him and i did the measurements out on it yesterday and i used the lxhxw / 1728 to get the cubes of the box and it came out to 2.4 in a sealed box, jl reccomends 1.375 after sub displacement am i losing alot by having such a big box cuz it sounds decent for still having 8 seats in a durango but would like to go louder as i plan to put a second 12w7 in by summer but for now i was just wondering if cutting the height on my box and resealing it closer to the jl reccomendation would help any. any input on this would be great seeing as im pretty much a noob to this. thx :unsure:
