Yes on the Y adapter question.  We need more info to answer the woofer question.   What is th impedance of the woofers?  What is the minimum safe operating impedance of the amp?

subs  are 4 ohms.           amps min imp.  is  At 4 ohms, the amplifier is able to produce 100 watts of power for 4 channels. At 2 ohms, the amplifier is able to produce 150 watts of power for all 4 channels.  does this tell you anything ?  sorry dont know much about this stuff yet..  the amp is just a visonik   V417SX  if that helps.

if that would not work  what do you think about  a pioneer  GM-X862.  760 watt 2 channel amp i also have laying around i could use just for the subs and leave the 4 channel for the other 4 speakers   ?

Wiring the subs as you described will be a 2 ohm mono load.  That will not be good for that amp, nor for the 2 channel pioneer amp.  You need to wire one woofer to channel 3 and one woofer to channel 4.  If you insist on bridging those channels on those woofers, you must wire the woofers in series.

Option 2 (series) = 8 ohm load
Speakers wired in series
Recommended Amplifier: Stable at 4, 2, or 1 ohm mono

Disregard the colors on the ends of the y adapters.  Connect the left RCA cable to one Y adapter.  Connect the 2 outputs of that Y adapter to both left inputs of the amp.  Connect the right RCA cable to the other Y adapter and connect both of those outputs to the right channel inputs of the amp.

Yes red on an amp or a radio is always right.
