My amp is on, not in protect mode and no sound is coming out of my subs. I already hooked up another amp, another sub, and new speaker wire...and it does the same thing, green light but no sound...no fuses are blown this all happened right after i upgraded to more powerful subs with no capacitor, but it wont come back on now???????????

are you factoring the ohm rating from running them parallel?
2 x 2o subs parallel = 0.5 ohm (lowers ohm's)
2x 2oh subs series = 4 ohm
IT is posable that you are calculating the ohm rating fine, BUT some SUBS can reach lower ohm rating while hitting bass- i didnt know this till i had a rather insane sub that would dip to 1ohm while hitting hard bass causing my amp to go into protect mode.
Are you setting the bridge switch for both left and right or are you trying to run both subs off of one set of terminals? If you running the subs off one set of terminals you are effectively running the amp below 2ohms and thus the amp is not 2ohm stable and you will destroy it.
Some amps actually all ready run a bridged output for left/right operation, this could also be the reason why the protection circuit is kicking on.
Either way it's a component mismatch and you either need a stronger amp or different subwoofer setup.
If the sub isn't working, you won't get a pop. All you need is a small speaker. Don't need a sub, you just want to test the sound. I recently blew 2 subs, no smoke, no smell, no sign of being blown. Absolutely nothing from the subs.... In the past my sub locked up. You can take your sub out of the box and hook the + and - to the battery to see if you can get the sub to pop there. I believe a small box will push a sub into a deep excursion to the center of the cone. I have 2 lanzar VW12D's that just quit. I hooked a 6 x 9 up to my amp and low and behold I had sound! Try that and see what you get...
First disconnect the subwoofer wires from the amp, turn the car off and back on...is the amp on? If so your subs are shorting it out, either from a frayed wire, or blown subs.
If it is still in protection mode, check the fuses in the side of the amp.
You cannot parallel two subs AND run them on the Bridge. You must have at LEAST a 4 ohm load on the bridge, and 2 4 ohm subs in parallel equals TWO OHMS. BAD!!! Move each sub to it's own channel or your amp will soon fry.
