speaker box construction question

[Doug[_2_]]

I'm adding a pair of 6 by 9" speakers to my Nissan Pickup. There is
no place to mount them in the truck, so I plan to build a box for
them. The box will be hung or mounted to the back wall of the cab. My
question is, do I need a port for such a settup? Obviously this will
not be a really powerful system, I'm not expecting too much, but I
just want to make the box correctly to maximize the quality. I also
want the box to be removable, since it will take up enough space to
make the little seat in the back unusable, what do people recommend
for a way to plug in speakers and unplug them (insulated plugs of some
kind?) Thanks for any suggestions.

They shouldn't need to be ported - 6x9s are typically designed to mount
in an infinite-baffle setup, such as a car's rear deck. A big spacious
box will work as well as anything.

Any sort of flush-mount spring terminals or binding posts will work for
easy removal... these, for example:

Something flush-mountable like this is preferable, as it doesn't leave
anything protruding to get snagged or break off.

If you plan on removing the box often, a quick connector may be of
interest. Bare wire into spring loaded connectors are impractical for
this and can pose a lot of issue : possibility of short-circuit,
unexpected phase reversing, the need to periodically reskin the wire to
get fresh copper...

I would suggest finding and installing Speakon connectors. They are
made by Neutrix. They are not common in car or consummer systems but
are the de facto standard in pro sound. The connector have those
outstanding advantages and characteristics :

Sturdy
Feature 4 contacts (2 channels on the same connector)
Fool proof - will go in only the right way
Locking
High power handling

Good suggestion Eric, I didn't even think of that (and I used to work in
pro sound, too).
