Chent81 Posted July 22, 2018 Report Share Posted July 22, 2018 Whats up fellas, I have a 2000 honda accord coupe with a pair of Crossfire bmf W15D’s that ive had for over 10 yrs. And I have a pair of Fi BL 15 D2’s that ive never hooked up. But im in need of help on box dimensions for them or for 1 of them at least. Could b powered by either a hifonics 1000D or a MA hk-401sx. Any inputs and ideas would be very appreciated. Link to comment Share on other sites More sharing options...
Chent81 Posted July 31, 2018 Author Report Share Posted July 31, 2018 Ok well i found a designed box for 1 of my Fi BL 15 D2 so i made it and like an Idiot i forgot to double check my Dimensions on my trunk opening da box didnt fit in my trunk. Total dimensions of da box i made was 19h x 34w x 18 1/2d to give me a 3.9 cubic ft tuned at 32 hz. So now i gotta come up with another solution. Can somebody pls help me ???

Joe X Posted July 31, 2018 Report Share Posted July 31, 2018 The first step would be building a cardboard test box and see what will fit, post the max size that will go inside for further help, the sub itself will work in 3.8 cubic feet but not much less.

hispls Posted July 31, 2018 Report Share Posted July 31, 2018 If you plan to run 2 15s in a Honda coupe you'd better be planning a wall build. How to avoid making a box that won't fit in your trunk (yep, we've all done it). Link to comment Share on other sites More sharing options...
Chent81 Posted July 31, 2018 Author Report Share Posted July 31, 2018 Ok i came up with this after last post. Let me know what u guys think of it. Max dimensions - 17h x 36w x 18d now for what i came up with... thinking of a 3.5 cuft @35 hz = 16h x 32w x 15.5d with a slotted port of 2w x 16h x 14.4d could this work ?? Or am i missing sumthing ? Never made a ported box b4. Always only made sealed. Link to comment Share on other sites More sharing options...
Joe X Posted August 1, 2018 Report Share Posted August 1, 2018 If you really can get in a 17h x 36w x 18d box then here is a suggestion, power: to sub rated, amp subsonic filter to 28Hz, minimum port clearance 3 1/2", figure is just an assembly guide: NOTE: If building outside you need to build a cardboard dummy box to test fit in it's way inside (again).

Chent81 Posted August 1, 2018 Author Report Share Posted August 1, 2018 Ok koo thanks alot for da help. Ill get started on it this weekend. And ill gonna build it inside this time. Lol. Once im done ill try to post up sum pics or a video. 1 more question tho...... i know ill b upgrading on power some time soon but with this box would it b ok to have my lil hifonics 1000D on it or should i throw my MA audio HK-401sx for da time being til i upgrade ?? And thanks again for da help. Link to comment Share on other sites More sharing options...
Joe X Posted August 2, 2018 Report Share Posted August 2, 2018 The sub can take either amp, if you have the electrical I would go with more power but you can test both and see which does it for you, don't think the Hifonics will hit 1K rms though. On the box make sure you can build outside since you have two options to try, firing forward or back and see which is better, if you build inside you could not try both, if the box dimensions need to be updated I can change them no problem.

Chent81 Posted August 27, 2018 Author Report Share Posted August 27, 2018 Ok so i completed da box and i got it in da car. Just havent hooked it up cuz im waiting on sum 0 gauge wire to do da Big 3 upgrade. Now i gotta ask whats da best way to tune it to avoid any distortion and clipping. Will post up sum pics after i tune it da right way This would b my 1st complete install alone. Ive had many systems ( six 10’s and six 12’s and a pair of 15’s ) but never tuned them. Always had a buddy tune it for me but he’s no longer around. And i know i still consider myself a noob at this. So is there any other special tools would b very useful to have ?? I was doing sum research on sum oscilloscopes but not sure which 1s would do da job. Link to comment Share on other sites More sharing options...
SkarredSierra Posted August 27, 2018 Report Share Posted August 27, 2018 Just get a dd1. Steve sells them. Super easy and almost foolproof tool for setting gains. Idk if any are in stock tho. If not there is a tool finder thread on here that should help you find some1 near that will help you tune your amps. Link to comment Share on other sites More sharing options...
