Simple guide to a miata trunk subwoofer
I made this up a while ago. It basically calls out a recipe for a good-sounding small trunk sub for a Miata. Ignore the naysayers. This is a proven and awesome setup.
http://fixjunk.com/index.php?title=Miata_Trunk_Sub http://fixjunk.com/images/2/28/Trunk_sub_2.jpg The theory behind this design is that it complements the small size of the miata and the peaky low end cabin gain from the trunk and interior. If you design your sub to have a flat response down to 20Hz, you end up with a giant gain in the low end and you'll just waste amplifier power and rattle your trunk apart. More techy details of the testing done by Jason Cuadra can be found here: http://www.diysubwoofers.org/projects/other/cartf/ |
Love the bungy cord! lol

Is it a 10" sealed?
where is the amp, spare tire well? https://www.miataforumz.com/attachme...ine=1312157774 |
yes amp(s) are in the spare tire well. which is hard on an 01 because there is a spare mount there. was. :)

Unrelated question: I see that you have a hydraulic strut for the trunk lift. Is that stock for NB's? How well does yours work? I installed a an unused second-hand kit but it doesn't lift my trunk lid on it's own.
|
i used an aftermarket kit from moss I think.
it doesn't lift the trunk by itself anymore but it does hold it open. it never did open as far as the stock springs. I guess at this point it's doing nothing for me that the stock springs didn't do. do you have a spoiler? |

https://www.miataforumz.com/attachme...ine=1315421903 DIY rack & off the shelf amplified tube sub. https://www.miataforumz.com/attachme...ine=1315421903 The amplifier on the rack is powering two 5x8 speakers with enclosures that sit on the parcel shelf. I can remove the rear speakers, the sub and the rack in just a couple of minutes for track duty. While the sub definitely adds range, I think I might try opening up some of the parcel shelf to get more sound into the cabin. The rear speakers were by far the best addition to the overall sound quality in the car. |

I will tell you, that "carpeting"/insulation/sound deadening you left on there is junk. It will mold if you spill water on it and its hardly worth keeping if you have dynamat. I would just take it out, put in sound deadening and either spray it with underbody spray or cut out some stock colored carpeting (I will sell you my carpet for shipping cost and a happy meal dinner lol).
Don't want to cover the trunk plugs in the floor pan because I have actually needed to use them to get into my locked trunk. Hopefully this won't ever happen again but if it does, I'd have to break the latch to open the trunk. https://www.miataforumz.com/attachme...ine=1315424415 I also have the entire parcel shelf and behind both door panels covered with Dynamat. |
ha! I wonder why mine was molding. Anyways, your setup looks very clean otherwise.
