that is an amazing story

looks good Lee, great job, how much more port length wouldve been required to hit 31hz? I was thinking possibly making a sliding port that goes over the permanent to be able to adjust the freq further...i just run in to issues getting it in the truck at that length, once it is in the truck that is a different story

i know this is an older thread, but Quentin, where is your facility at, up near folsom or down closer to NOL?

jamba juice = swahili for fart juice

i wouldnt call it pussed out, 175 on two or four wheels isnt pussing out.

179 on a cbr929rr..those were the days...only did it once, to see how regearing the sprocket

looking good bro

yeah the trap box plans with 18" bottom depth was sitting on the rails...the furthest the port using the 6x13 3/4 diameter space between the rails could go is 24"...will be tricky trying to get it in the truck if we go any larger... just know that the plans i sent was for 3.6 cubes after sub displacement only..it didn't include the port area, 3.25 ft3 is the max optimal volume for ported box for the zcon 12

that looks great. i wish i had the talent to make boxes and do customization work like that

great log Lee. As far as system beating...this setup pounds. I was able to get a taste of it and it went down nicely. I am highly impressed by system as a whole, the box, the wiring, everything. Definitely didn't cut corners.

good, i am tired if playing small ball, i want to play big ball! i'm ready to have some fun with my music...i hope to have some sort of flex because my last 2 subs were not able to provide me with much...

it is a toyota tundra double cab... the port would be pointing under the front passenger seat

Leedog, the seat rails are not spaced evenly side to side, from the left rail to the wall is 5.25", from the right rail to the wall is 3.25

The above link shows no port height to width ratio, its port area vs port speed. i was also googling stuff up, in addition to your link you provided.

my mechman alternator doesnt have an adjustable pot, my ECU controls the voltage output of the alternator

i appreciate all the feedback, as currently being discussed in another topic, prior to joining this group this week, i was also on the DD1 bandwagon. I am glad I didnt waste my money.

yeah the 13x6 area is between the seat brackets, i have to get back to my truck to verify that it is centered in the 22.5, still stuck offshore..unsure when i will get back in

let me go back to the drawing board with this... thanks for everyones input. it is much appreciated

i could go up with height some, and possibly depth, but width is restricted to 22.5..unless i had a non-rectangular box, then that would add 13 x 6 box to the bottom

i cannot go any larger then the box dimensions given in the first post..that is the largest i can go without taking seats out, and i am not willing to do that

understood about the big boxes, hence i wasnt going minimum volume requirement chose a happy medium at 3 cubes

messing around and researching, i see where it says square port HxW ratio shouldnt be more than 1:8, what is the reasoning behind that?

RF 1500BDCP, and since it isn't enough area, i guess it will have to be a square port then

yeah, but i saw that huge invisible sarcasm sign with that post too
