|
|
the trunk is 32" wide at its max, the box cannot be any wider, you can get a max depth of about 22 inches, and a max height of about 15.5".
subs considering using are 3 12" MTX 7500. |

u can fit 3, with most surface area gone and little space for port > wasting time
2 in that space would sound better than the 3 fitted. |

| I'm pretty sure you can get it to fit without glass and some imagination. With that space you really thinking of going ported with 3 subs? And if you going sealed then you may get greater output using only two ported as these guys suggested. |

| Don't forget that you mentioned max dimensions. You need to cater for material thickness and port, bracing & driver displacement. Damn thing creeps up on you if you don't pay attention lol |

alright maybe this might help meh case a little is a honda accord 2004 model i have.
what about doing a box like this i could build it in parts, maybe three seperate parts and then assemble it in trunk. And i realized if i take off the plastic case for the backseat locking mechanism i can go up to 17" tall.

| so three subs all facing up, port firing through center console fold down in the backseat, with my little design to increase air space. |

you mean +crease enclosure volume, rite? why not build the sides of the box slanted inwards? broader at the base & thinner at the top for the trunk hinges to pass.
but under all seriousness, that 3 2" idead sounding kinda like a longshot.
you young, you will learn from your mistakes. try the three & then try 2 ported, a simple face plate change will do the trick. |

this speaker?
think that the min recommended volume is 1.45 cubic ported, so you basically looking at 4.5 cubic for all 3.
not impossible, cause the dimensions that you wanted to work with [2.6*1.8*1.3] working out to around 6 cubic.
with speaker and port displacement you SHOULD be right around 4.5 or a little more
i'd say a common chamber would be the easiest to design, but its not extremely difficult to get each in single chambers (just have to do the calcs.
this is what i'm thinking. (for all intents and purposes its to scale (just adjust the depth to account for the slant)
and you can port either on the front face or at the back (off center)
if you account for the slant (assumed 75 degree angle) you may be able to exceed the 22" depth be about 4-6" |

u wont buy that speaker and put it in 1.45ft^3 > wasting time.
But if u got a 17" height this could work out, you could do one long slot port at the bottom.
and get the biggest box u could get to fit,
thats whats going to screw you on this experiment,
but it can work, i had a 11.5ft^3 removal box in my trunk already. |

imo, such big boxes can get frustrating to work with over time.. what i would do is get a pair of high powered 10"s or 12"s or a single 15".. that way you won't have any issues getting the enclosure in / out of your trunk.. AND you will be able to use the correct volume to get max performance out of your speakers..
remember a pair of 12"s in their ideal enclosure can outperform 3 12"s stuffed into a small box..
maybe even consider doing 3 10"s.. |
