Next time don't buy these components at Radio Shack.
Yes, they are very convenient but you can save a lot
of money shopping around.
Radio Shack charges $20.99 for a 4" 12vdc fan.
At All Electronics you can get a 12vdc 120mm fan (4.7")
for $4.25. And the metal fan guard you will need so you
don't whack your fingers is $1.60. (Not available at RS).http://www.allelectronics.com/index.php?page=seek&id%5Bm%5D=pattern&id%5Bq%5D=120mm+fan&x=0&y=0
They also carry LED's, switches, project boxes, and
all sorts of components and spiffy stuff. At least get on
their catalog mailing list as their inventory changes.
If you plan to build more projects, you will always find
something you need at a great price
at All Electronics.
I have purchased a 2900 to put in my Jeep figuring that the 75w high power setting could be good for some of my back country adventures where cell phones don't work.
So are you going to mount it under the dash in your Jeep?
With the fan blowing from the bottom up?
Some of these 2m rigs have a downward firing speaker,
I don't know how the fan would effect the sound.
you can always get an inexpensive small MFJ Extension Speaker.
They are about $13.99 and actually aren't bad.
Good luck with your installation!
