  1. Ok So I recently finished the installation of my new BL fully loaded 18" with a RF 1500-1bd with the help of some friends. Before I installed it my cd player (Older Kenwood) would play any CD. Well I was listening to it and my CD player shut off and wouldn't work with any CD at all. Finally it started working. Anyone know what could be the problem with this?

    My next issue is that my bass hits so hard it makes my CD skips. How do I fix this?

    My next question is I'm using a stock altenator and 1 battery. My lights will dim while bumping so I was just asking if I will need a new battery and possibly a new alt in the near future ? ( will I sub kill my alt I have now?) All critizism and comments are welcome.

    Need all the help I can get.

  2. So I just ordered my 18" Fi fully loaded BL and I can't decide what amp I want. My friend from school told me that the Sundown Audio 1500d is a damn good amp for it and I can get a refurbed one for 350. 1500 watts RMS. Any ideas on what would be a good amp? I want to push the sub with the best amp i can get for 380....please help me. :)))))

  3. hahahah well....If anyone lives near Knoxville, Tennessee...Don't fucking let lowes cut your wood. THey messed it up horribly. Bigjd and I are gonna have to true it up with a sander to make it look good. The box looks good, but it needs sanded.

    It was hell bringing the wood back to jd's house in my lil 93" mustang. I somehow fit 2 sheets of MDF in it. I have pictures it :)

    We didn't really get to take pictures of it while we were building it, but I'll post some pictures build box, and the wood in my car :) I dunno how the hell I made it home without getting a ticket lol....It tooks us 2 days to build, and tommorow I'm taking the top of it to school and having the circle cut out of it for the sub.

    I'll post the pics later :)

  4. Alright..I plan on getting the fully loaded 18" BL. and a HIFONICS BXI2006D MONO BLOCK AMPLIFIER. If I get the 1 ohm sub what would be the safest way to hook it up to this amp without damaging the amp or sub. Whats the lowest ohm you can get with the 1ohm sub vs. the 2 ohm sub?

  5. Well..I think I'm all set. I'm going to lowes tommorow after school to buy my wood. You have no idea how much of a help you have been. You've taught me alot. I knew nothing about volume or anything until I came to this site. I just went to radio shack and bought a box. It costed me 109 bucks! anyways thanks alot man. I'll post pics of the build, and will give you props for the help :) My friend and I are going to start it tommorow...He knows what he is doing. I'm not so sure about me though.

  6. You are amazing in my book. I'm decent in math, but when it comes to 3d objects..I just can't understand it. I think it's because I'm left-handed or something lol. Anyways I will be going to homedepot and lowes tommorow to check the prices on MDF. and I read on one of the post that lowes will cut the wood for you for little to no cost. so I would need 7 pieces of wood right?

    and please correct me if I'm wrong, but would I need (2) 13.5x35 cuts. (2)35x35 sheets. (1) 13.5x18.5 (1)13.5x33.5 and (1)13.5x26.5?

  7. u are figuring displacement wrong. you dont just figure the piece of wood used for the port for the displacement....u also have to figure all of the space in the port into the displacement equation also. so essentially it would be the height of your port x the width of the port (plus .75 for the wood) x the length of your port....

    with that being said, if your port is 13.5"hx 7"w, then your port actually only needs to be 22" long to get ur tuning to 34hz. and the piece of wood for the port only needs to be 18.5" long (although the total port length is the actuall length plus half of the ports width (called end correction)...in this case 18.5+ 3.5 (<--half of 7)....which would give u an effective length of 22")

    box outer dimensions: 15h x 35w x 35d

    box inner dimensions: 13.5h x 33.5w x 33.5d (8.77cubes gross)

    port: 13.5h x 7w (gives u 94.5sq" of port area--12.74sq"/cft) x 18.5d

    port displacement: 1.12cft (13.5 x 7.75 x 18.5= 1935.5625/1728= 1.12cft)

    net box volume: 8.77 -.23 sub - 1.12 port= 7.42cubes

    tuning: 33.8hz

    Wow...you are amazing, but I still have one more thing to ask. My box is going to be 33.5 inches deep inside. So is 18.5 long enough? Thats like 15 inches for air to travel into the port. Is this too much? and also How do you calculate the Hz of a port? You explained all your calculations but that one :) so that still confuses me just a lil. and also man I thank you soooooo much for the drawing you have given me. Did you use google sketch to draw that? It is amazing. If you ever need anything just ask :)

  8. Alright....so I've been trying to figure out displacement. I'm pretty sure my box is going to be a 14x35x35. my sub's displacement is .23f^3. I still need the volume displacement for a piece of 3/4 inch MDF bored that is 13.5x30 to seperate my sub from port. I've tried to figure this out, and I've came up with the following calculations. .75x13.5x30=303.75/1728=.18f^3 displacement. Can anyone correct me if I'm wrong on this?

    And since my box is going to be 14x35x35=17150/1728=9.92f^3. So subtracting the subdisplacement of .23 and my if my calculation on the 13.5x30 f^3 (.18volume) is correct that will gives me a 9.5F^3.

    If this is correctly calculated what would the demensions of my port have to be to tune my box at 34hz

  9. I live in a small town called LaFollette. It's in Tennessee. I've been to serveral lumberstores and ask if they carry MDF bored...and they don't because they don't sell enough. I can go to homedepot. There is one in Knoxville (I'm right by it.) and how big is the 3/4 sheet of MDF? and man that would be awesome if you could get a sketch for me.

    I really need these demensions because I'll be buying my wood soon. I'm forsure going for mayb 15x35x35 so I really only need my port demensions for 34 Hz

  10. Don't use plywood. Its not as dense and can resonate & delaminate. Use 3/4" MDF. Hopefully someone can come in a do a sketchup to help you with what the box should look like.

    No store in my area sells MDF bored. so I dunno where I can get it. I've asked hardware stores and they say that they don't sell enough of it to carry it. Can you order it online?

  11. kk...So my new demensions are 15x35x35. I'm using 3/4 inch plywood. this will give a gross volume of 10.6 cubic feet. I plan on having a double baffle, my sub ( which has a .23 displacement), and a Port that is tuned to 34Hz. So..what would the demensions of my port need to be for the sub box to be tuned at 34Hz.

    I also need to know what kind "maze design" or what ever it would be called that I need to seperate my sub enclosure from my port? I was thinking of just a piece of wood that is mayb 13x35? I'm not sure on that. if anyone out there can would you mind taking this into displacement when firguring out my net cubic feet.

    Once again..Thanks alot! all comments are welcome!

  12. You want something made man, what tones or sweeps you need?

    No It's alright. Thanks for asking though. See what I was gonna do was make a CD with serveral different tracks ranging from the highest frequency my Fi bl 18 can pick up, to the lowest it can pick up so I would have soemthing to test it with when I get it installed. I know they have serveral different tracks out there for this, but I wanted to make my own and customize it :)
