Old Cerwin Vega loudspeakers, as ^^^^ said....  that's what got me into speaker-building as a hobby...looking at ways to use the drivers out of those huge old cabinets.  After a while you get over the tendency to worry about using the "right" speaker for either home or car, and you just experiment.
Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

so you're saying just do what I think is right, and work from there?

dwrwebb, the individual drivers in those CW cabinets are connected via an electronic crossover.  This crossover consists of coils, capacitors and resistors.  They are connected like this so that each driver plays a certain frequency range and interact with each other harmoniously.  Now, what you think is right and what I think is right are probably two entirely different things...so....the answer is no.  But, it you're bent on destroying the old speaker system anyway and won't suffer the loss, then yes...experiment.  You can only grow from there, which is the way I did it.

actually, I dont want to gut the thing.  I don't really want to get rid of the speakers, but our apartment is too small to use them, really.  I just thought if I could gut them and use the speakers, I could get some good out of them.  I guess thats too much for me (as a beginner) to try.  I am having trouble figuring out the wiring in the enclosure, and thought maybe Id just strip it all, keeping it as a unit, but just out of the current box....maybe just lengthen the current wires, that way they are all connected to the resistors, etc., just not located all in the same enclosure.   Would that work? what about in my car?

What is the power rating on them?
I have not failed. I've just found 10,000 ways that won't work.

Not bad, Cerwin always did make some hard hittin high-end stuff.
Looks like it will be ok with what you are trying to do as long as you match up fuse ratings and proper airspace.
