Multi-Amp setup

Im new to this site.  Ive been reading alot of the posts just trying to gain more knowledge as I can tell there are alot of people with a great deal of knowledge on this site.  Im going to be installing a stereo in my blazer which will include 3 sub-amps.  The amps will be 2 MTX1501D powering 1 15" RFL and 1 MTX801D which will be powering 2 12" MTX 9500s. 

What is the best way to go about this?  I have basic knowledge of what im doing but I am not sure what the best way to begin this install is.  I want the 12s to be used during daily driving while the RFL will be there for days in which i need deep loud bass. 

Please Help!

ditto DYohn's suggestion.  And I'll add this:

• The remote lead carries less than 1/2 ampere, so the simplest, cheapest ON-OFF toggle switches will work.
• The remote can be split to two wires by soldering a connection.  Each of the two resultant remote wires would have its own toggle switch.  You can place these switches up front near the driver's seat so that you can toggle the amps conveniently.
• Put a fuse holder and fuse, value 500 mA (1/2 amp) in the main remote wire near the source (deck).  This complies with the hard and fast rule that all power wires must be fused.

examples:  toggle switch, fuse holder and fuse

Another way to toggle would be to use a switch like this one which would do the job of both standard toggles.  With this one it's either one amp or the other on at a time with no chance of running both at the same time.

Using the toggle switches is what I was planning on doing.  I was going to wire it up to control both MTX 1501Ds on the same switch and the 801D on another switch.  Should I use a crossover or anything?  I currently dont have any fuse on my remote on wire is this something that I should do since I will have the remote on wire split to turn on 4 different amps?
