Yes put the positive wire where the negative wire was and vice versa.  Do this only on one woofer.

ok will do. I'll have to try it tomorrow. I'll post my findings in the morning. Is there anything else it might be that I could try if that doesn't work?

You could try connecting each voice coil by itself to make sure all 4 of them are in working order.

Ok I hooked up each voice coil and they're all good. I reversed the positive and the negative on one of the woofers and it didnt play as loud so I wired it like i had it before. I tried each sub by itself and each one was equally as loud as the other. If I ran each sub from it's own terminal and combined the wires into one of the quick connect plugs, would that be the same as running them parallel? I only have one of the plugs so that would be the only option. By the way, where could I purchase n new qucik connect plug?

Yes, if same-polarity wires are connected at any point it is parallel wiring.

Build the box so that it performs well in the worst case scenario and, in return, it will reward you at all times.

I noticed that you said you reversed the wires on the wooferS.  Did you miss the part about only one woofer?

I think I remember that you have a box with 2 chambers and 2 sets of terminals.  Let's change this up and wire one woofer to it's corresponding terminals.  Wire each woofer as shown in the following diagram.  All of this picture is inside your box.  After you wire the woofers this way, play each woofer by itself to make sure it is playing, if they each play, we are now going to wire the speakers in series.  You will need to follow these instructions precisely.  Disconnect all wires that run between the amp and box.  Connect a single wire from one of the positive terminals of the amp and connect the other end of that wire to the left positive terminal of the box.  Now connect another single wire from one of the amp's negative terminals to the right negative terminal of the box.  Now you ahould have 2 wires between the amp and the box.  One from a positive amp terminal to the left positive connection on the box.  The other from a negative terminal of the amp to the right negative terminal of the box.  If this is correct, proceed.  You will now have 2 empty connections on your speaker box, the left negative and the right positive terminals.  Take another single wire and connect these 2 terminals together.  THE ABOVE CONNECTION IS ON YOUR SPEAKER BOX.  Do NOT connect the unused terminals of the amp together. 

Let's recap before you turn the amp on.  There shouid be one wire from one of the positive terminals of the amp to the left positive wire of the box.  Then there should be a wire connecting the left negative terminal of the box to the right positive terminal of the box.   Then there should be a wire going from the right negative terminal of the box to one of the negative terminals of the amp.  There should be 2 unused terminals on the amp.  If this is not the case, stop and do not turn the amp on.

Wire each woofer as follows and connect it to the terminals on that side of the box.

 

Left Woofer

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

Right Woofer
