SIMPLIFY.
Two 10" subs, each 4 ohm dual voice coil.
wire the coils in paralel for two, 2 ohm loads.
Then wire one sub to each output of the amp.
That amp will give you 150 w rms on each sub.
OR, you could wire the two, 2 ohm loads in series for a 4 ohm load and run the amp bridged, but still,
it's 150 wrms per sub.
No, that's not much. No, you won't hear it outside the car.

One of my friends said wire them at 2ohms mono....Right now i'm not sure how it's wired, the subs came already in the box, so I just put +- wires from each sub box terminal to the amp terminal for both L+R....Id atleast like to know how to wire it to get 150 watts to each sub insted of the 100 watts it may be getting now

You won't be able to get a 2-ohm load (mono, anyways) with dual 4 coils... you can either get a 1 or 4 ohm load by wiring the subs together, or the mentioned 2 ohm load per sub if you wire one to each channel. Following the suggestions above would be your best bet.

If you put 2, 2 ohm loads in series, you'll have 1 ohm load.
So, if you want more power on the same subs, you can BUY a mono amp that does 600 rms @ 1 ohm.

Really I have no clue what ytour talking about, your picture is confusing and theres only one subwoofer, I have 2, if you wouldn't mind could you find a better picture or even draw one in paint, or pick one from that site, like I said, I'm brand new at car audio...
