Motorhome accesories include the use of 2 batteries with diodes. So check
with some local motorhome dealers.

Is it possible to run two radioshack switching supplies in parallel? I
have tried it however one always seems to shut down, so i would only be
getting 25 amps max. I need all the amperage I can get because I am
running two car audio amplifiers in my room... Thanks for any advice
or instructions!

Yes, you just need a diode in series with each power supply's output
so they are isolated from each other. Schottkey diodes are
recommended for the lower voltage drop (and less power lost).
