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!

Why in the Multiverse would you need that much audio power in your
room?

Do you have no concern for the quality of your hearing in later
life?

sigh Ahh, well... You need to diode-isolate the supplies, as has
been pointed out. I would add that it may be a good idea to use Schottky
power devices as opposed to generic diodes. Schottkys have a much lower
forward voltage drop.

Run the positive lead from each supply to the anode side of one
diode. Tie the cathode side of the diodes together, and take your common
positive output from there. The ground leads may be tied together
without isolation.

Good luck. Hope your neighbors don't object to the noise.
