I normally ude 3m's green autobody tape. It is the best I have used. But I'm not spending $25 a roll when I ca just clean the goo off afterwards. I will be going 1.8 cubes net and the cavity came to 1.875 cubic feet. I'll post how I got that a little later.

First claen all surfaces to be masked with alcahol to remove dirt and grease. I normally use a better tape because this cheap stuff will leave glue residue when it heats from the resin. However I am not concearned being it's my vehicle. mask off all areas be sure to get in all the little nooks. This will make the enclosure more rigid I use heavy painter's masking paper instead of cardboard because it is easier to use. mask off all corners making sure they all have a nice smooth slope

Fb=((14630000*(D/2)*(D/2))/((Fb*Fb*Vb*1728)-(1463*(D/2)))) here's your formula for determining tuning frequency with volume in feet giving you port length in inches

The tuning frequency is not the peak. By definition the tuning frequency (f) would be where the responce line sits at zero db.

You ought to cut that smart ass attitude out man, I didn't ask for your fancy wording that a normal human has no idea what it means.. Got off of my topic please and I'll recieve help from real people. And besides, I'd rather put the x in the 29cg chamber. Thinkin of goin with a 47h slant on the 63 curvature. That's exactly the reasoning behind my first post because I knew you wouldn't understand or take the time to google basic t/s parameters and terms needed for designing and using any box building program. And no a sealed enclosure will not give you a flat responce curve if it is not the correct volume.

I pity people who are constantly think negatively, you live longer when you are happy.

snappy commnets like "causing the word to end" around here will get you no where especially when you already stated you were over your head. If you fully read the instructions that are posted in the file with WinSd you would have a llittle understanding of the program and what each function means and shows. Yes moving from 32 to 36 hertz while keeping the same volume can have dramatic effects on responce. At a give volume tuned to 32 hertz can give you a nice flat respnonce curve, while moving tuning to 36 could give you a 3-5 db peak with an f3 way above your desired f3. When tuning low and I don't mean 32. 32 hertz is no where in the realm of low, when using an enclosure too large for the driver's Kms it is very possible for the enclosure's "f" to be way above the actual tuning. I didn't say all that before because you stated you didn't know anything about designing an enclosure. And most of the time it is easier to give people what they need instead of giving them what they think they want.

I highly recommend going with Fi's recommended enclosure specifications. Winsd will assume you are wiring your sub in series which most t/s parameters are derived from which will be different from parallel wiring and will throw off the response curve. Also the stiffness of the BTL will give you a real funny response curve as well because it is beyond Winsd modelling ability. Nick has stated this numerous times.

I haven't had a system in my dd for a few years now. I drive nearly 1,000 miles a week so I am in need of something. I normally have a lot of junk I need for work so this install will save as much space as possible. Through out the build I will show step by step some of the techniques I learn over the years. Factoy interior, hopefully the end result will look like this as much as possible. spare tire location under false floor false floor removed farm6.static.flickr.com/5267/5666965605_2a85e9c267_m.jpg tire cover removed. tire will remain remember this is a daily driver. jack and such will go in side pockets by the tire well the sub the sub will go somewhere in this location initial masking tire reinstalled

Needs to be conducted to show results. This constant arguing is going to go nowhere and I am personally ashamed to see it

Is it possible to do a sound sweep in the car with a termlab in it? If the output measured by the termlab corresponds with the other graph then we can agree that the system does indeed create pesky output demonstrated by the graph. If not and the termlab shows a relatively smooth response then so be it. A debate is just arguing. If scientific theorems and such are going to be brought up, and I am one to use tried and proven formulas and techniques when building enclosures, then a experiment

Like this???

No, I said to take the carpet off the back of the seat.

You can pull the carpet off the back of the seat and cut a few of the triangles out of the plastic backing on the seat. Then glue the carpet back with contact cement. The below vehicle sounded real weak with two flatline 12's. It was a night and day difference afterwards.

link worked fine for me but i'm sure you can find fedex's homepage.

it's collecting dust waiting on subwoofers

it'll fit. I've done a rockford p3 12 ported. The bottom of the seat is not solid.

1) unhook sub wire from amp 2) us a double A or a 6 volt battery and tap each end of wire to battery terminal, positive wire to positive terminal and negative wire to negative terminal. 3) sub should move out. A)If sub moves out then you have other problems. B)If sub does not move out go to step 4 4) remove sub from enclosure and repeat step 2 on each individual coil. A)each coil should make the sub move out. B)if each coil does not make the sub move out you have a broke woofer. ALSO WHILE THE SUB IS OUT MAKE SURE THE RED POSITIVE TERMINAL ON EACH COIL IS ON THE LEFT. These subs are hand made and it is possible the terminals could be backwards making the sub out of phase if you wired + to + and - to -

A video needs to be stickied, 28 pages are too many to scan through.

slot port

If you didn't do kerffed and inlayed port with just a normal black spraypainted port you would be looking at $210 plus shipping. But again I do not use the cheap trunk liner most use, I use a heavy napped carpet which is three time as much money.

shipping to Waco if the enclosure would be 90 lbs and 38 x 18 x 25 , which is hella huge would be 80 bucks. So you'll be between 50 and 80 for shipping plus packaging.

yea I am a bit more expensive than most, however I have a cell phone posted on here that I answer, and you don't have to wait till Christmas for me to get back to you. And I use better quality materials than most.
