Tunnel enclosure...

[coh33dkill3r]

Is there a formula to calculate the needed airspace for a tunnel???? Wanting to do 8 18s or 12 15s in a jeep Cherokee and don't know the first thing in designing a tunnel... What sealed space is needed and how much of an opening do I need for this to work properly

tunnel?

please explane?

post a pic or link to what you trying to describe

side note, don't aim so high for a first install,

either one of those boxes, is going to cost over 1k in material alone,

let alone 10x cheaper 15's available is $1400

cheap subs are low power so allow 400-600rms each,

thats 4-6k for 10 subs

thats a $1.5-2k amp

and another $1-1.5k in elect to support it

so $5k and thats going entry level on everything

not to mention the bus or truck you'll need to put it all in

you'll be better off running less higher end on same or more power for the same $$$

Not my first build but my first using multiple subs and a lot of space to work with

Are you trying to build a 4th/6th order bandpass or are you just planning to build a tunnel shaped box?

I always thought they were similar to 4th orders so maybe a 2:1 ratio ported:sealed

Tunnel shaped box like mr. P jeep

Anyone have any pointers for building an enclosure like this???
