    I will not be competing in SPL contests, i just want LOUD bass (doesnt every basshead). The sub i will be getting is a Fi BTL either a 12 or 15, unknown due to money, I think a ported box would be the best, but my buddy told me that bandpass boxes are better. He said a 6th order box would be good, i have no idea what a bandpass or 6th order box is. Are they louder for the daily user? As stated in title, the car i currnetly have is a 2006 Toyota 4Runner, in it, i have mids and highs by pioneer, and they sound good.

    ok i have a 2002 dodge dakota extended cab, and i was thinking of putting 4 SA-8's in the back area after taking out the back seat. i will get the D4 coil configuration and run 2 off a dsc1000.1 and the other 2 off another dsc1000.1 (each sub will get 500watts) now i have no clue how to design a box, the only other ported box i made someone else designed for me and i built it. i dunno max dimensions of the box but if you tell me how many cubes it has to be i can figure out how to make that size box fit where it needs to, also for the "easy" factor id like to use aero ports instead of a slot port design, so what size and lengh aeros would i need? and where can i buy thos…

    Hey! I´m new here Just ordered a Warden 18 2x2 ohms thats going to sit in my SAAB 9000 coupé in the trunk. It will get about 4500 rms from a Soundstream Goliath Tarantula XXX 6500D. How big box do I need? I want to play loud (ofc) but loud to music, not to pure sinewaves. The music I´m playing is Lil Jon, Ludacris, Young Jeezy... that kind so tuned to 30 hz would be really nice Depending on what the FS is. Cant find it *If I´m spelling something wrong its because I´m Swedish *

    I am pretty serious about doing a blowthrough to my F-150 in the next few months. I am pretty settled on 2 18"s on 4000 watts (will be more with upgrades in the future.) I was thinking of a 4th order bandpass box for them but I want to be loud on low hertz (like around 30-35). How can I accomplish this? Also, what would be better: 2 18" or 4 15" all on 4000 watts? Like I said, I want to be loud but hit low.

It will probably be dual chambered, wt the port on the end. Is that to big or not big enough is my question. It says it only needs 6cuft for sql, so i guess 8cuft for one sub isn't that bad.

    Hey everyone. I purchased an SA-8 after reading a ton of reviews and now i am ready to start building a box. Since i've never built a box before i downloaded a couple of programs which apparently i have no concept on how to use :/ I listen to a variety of music from metal to dubsteb so i'm looking for a a box that can do both SQ and SPL. From what i've seen online it looks like .6^3 box tuned to 35hz is the way to go. Sub is going to have 500rms at 2ohm feeding it. I was thinking of having the sub point towards the roof and the port firing to the back. The narrowest point in the vehicle is 38". I emailed ram design to see if they could design me something but i haven't…

    I'm trying to build a box for a single FI BL 15, fully loaded. I want it tuned around 32-33 hz. Also my trunk in my car is kinda small height wise, so I was wondering if it was possible to put the sub on the top of the box and lower the height a little bit so the sub doesnt get close to the top of the trunk. The port I want on the front. Is that possible? The dimensions I have so far are: Width - 32 Height - 14 Depth - 25 Port Height - 12.5 Port Width - 5 Port Length 1 - 19.25 Port Length 2 - 8 62.5 inches Total Port Area, 3.8 ft^3 for box. Tuned at ~32. Would it be possible to put the sub on top of the box with this design, and still have the port on the front?

    Well im swapping out my 2 SA10s each on an audiopipe APSM1300 for 1 SSA 10" XCON and i will be strapping both amps together to get ~2000w @ 2 ohms. It seems like I might get away with being able to use the same box and port length. The current box is 1.39ft^3 before displacement, making it 1.24ft^3 ... using the aero port calculator My exisiting 3" x 15" port will give me a tuning of ~30.8hz. Am i lucky and wont have to build a new box?

    I built this for a friend of mine. Its about 2.52 cuft per sub with 40 square inches of port per sub tuned to 36 Hz. The objective was to build a box that filled up the back of his truck. But that was too much air space overall, so we pretty much built a box inside of a box.. The pic of the inside looks pretty sick.
