ColumbusJBR Posted June 11, 2012 Report Share Posted June 11, 2012 Whats up guys. Prefab boxes are the pits, the one I had was like 0.87 cu ft tuned at something in the 40's. NO MORE! I have always wanted to build a custom ported box for it but didn't think I could do it w/ my tools and skill set, but for whatever reason this past weekend I said F*** it! Won't know until you try, right? The enclosure is just a simple rectangular slot port, designed to be about 1.4 cu ft net, ~35 Hz, 20.125 sq in port area. Going in my 98 Honda Prelude. Anyway, on w/ the pics! Took out the old framing blade that came w/ the saw New Diablo finish blade Building a circ saw guide for nice, straight cuts I was able to get away with only buying 2 2x4 sheets of 3/4" MDF. Saved me about $10 over a full sheet, plus these actually fit in the prelude. BARELY All the panels cut! Cuts are almost perfect, on one rip i think my hand let the saw come off the guide for an instant. Very slight wobble on a few edges, nothing too bad Big mess Quote Link to comment Share on other sites More sharing options...
ColumbusJBR Posted June 11, 2012 Author Report Share Posted June 11, 2012 Construction begins I found the port walls the trickiest to install. Difficult to clamp and screwing in blindly from the bottom. I had a few missed drills and some cursing but I got it in there. I learned you can't have too many clamps. I'm gonna go back to Harbor Freight and get some more while they're cheap. Its a box! Quote Link to comment Share on other sites More sharing options...
ColumbusJBR Posted June 11, 2012 Author Report Share Posted June 11, 2012 My jig saw cutout is functional, but embarrassingly bad. I should have practiced on a scrap piece! Now to make it pretty Here was my first big mistake. For symmetry sake I did the terminal cup cutout right in the middle of the back panel. Cut through to realize I just cut right into my port wall! OOPS! Luckily it still sounds fine, but next time I know to put the cup on a side panel. Gotta learn from mistakes, right? Priming begins Primer always looks like crap, but at least it makes the finish paint look so much better 1st coat of Rustoleum multicolor textured spray paint. I was skeptical, but am impressed by the product. Good stuff! Painting the inside of the port white Inside of cup was taped off even though it doesn't look it here. I think its just reflection Quote Link to comment Share on other sites More sharing options...
ColumbusJBR Posted June 11, 2012 Author Report Share Posted June 11, 2012 Time to get the sub outta the old box. GLADLY! Got some brand new hardware. T nuts and hex head screws Its in the car. Sounds great, but I'm gonna try flipping it around when it stops raining to see what sounds better. Extra trunk space is for the birds So there ya go. It's not perfect, but being my first attempt at building a box I'm pretty happy. My type R can BREATHE now! And it sounds awesome! I think I can officially say I'm done with prefab boxes, I proved to myself that I can build my own w/ pretty basic handheld tools, and its a lot of fun! As far as possible changes, like I said I am gonna flip it around soon to see what sounds better, and I may rethink the amp rack. I know there's a better way to use that space more effeciently. Thats for another day though. Let me know what you think or if you have any questions. I'm very open to constructive criticism, I'll be the first to tell you I made some mistakes and it ain't perfect. Nobody would ever get better if they didn't make mistakes.

RooTxBeeR Posted June 11, 2012 Report Share Posted June 11, 2012 Turned out good. I think 20 sq in of port is way to much though.
