Flex i have to agree with Dave and Razz, your asking too much of the 700.5 the sub alone is working it pretty hard and then the HLCDs are just jamming it up.

TO save the coin now, take the 200.4 and bridge it to the HLCDs this will power them up and it shouldn't overheat and then you can run the cabins to the 700.5 and i did that my first summer and that amp never shut down and i was pounding on my stereo pretty hard.

Ultimately get the Kicker ZX450.2 or another dedicated 2 channel to run your HLCDs and you will be golden.
