So you have a 4 channel and a 2 channel amp. You're trying to use the 4 channel amp to power the underseats and front speakers, and the 2 channel amp to power the sub. Correct?

Yes, and I believe I can go about this 2 ways. But im not sure which is the best and i need help. Let me tell you what i have and the specs of my equipment.
4channel alpine amp MRP-F300
-50 watts RMS x 4 at 4 ohms (75 watts RMS x 4 at 2 ohms)
-150 watts RMS x 2 bridged output at 4 ohms (4-ohm stable in bridged mode)
-2-, 3-, or 4-channel output
-variable high-pass/low-pass filters (50-400 Hz, 12 dB/octave)
-selectable bass boost (12 dB at 50 Hz)
-subsonic filter (15 Hz, 18 dB/octave for channels 3 & 4)
2 Channel alpine amp MRP-M500
300 watts RMS x 1 at 4 ohms (500 watts RMS x 1 at 2 ohms)
variable low-pass filter (50-200 Hz, 24 dB/octave)
variable bass boost (0-12 dB at 50 Hz)
subsonic filter (15 Hz, 24 dB/octave)
Polk 12" Sub DXi 1240dvc
12" subwoofer with dual 4-ohm voice coils
polymer composite cone with butyl rubber surround
power range: 50-360 watts RMS (180 watts per coil)
peak power handling: 720 watts
frequency response: 20-300Hz
sensitivity: 88 dB
Everything else is OEM. I also added the tweeter to center. And i have the technic harness hooked up and working.
My issues im having are how to hook all this up without putting stress on my amps, blowing the speakers or under powering them.All i want hooked up are the underseats and a trunk sub. Nothing else.
Questions
1. Can I power these with just a 300w 4 channel? or will i need to use my 2 channel to power the sub and my 4 channel to power the underseats?
2. depending on what i do can someone tell me where to put the settings on the amp?
3. On my sub as you can see in the picture its a DUAL 4ohm. how do i hook this up?
Sub
ill gets pics of the settings knobs once i decide which route to go.
THANKS FOR EVERYONE'S HELP!
