Technically the amp in your top diagram appears to be a single channel amp, with both subs wired in parallel to a single set of speaker outputs of the amp.  The bottom diagram, however, has the positive and negative alternating, implying that it's a 2 channel amp (+ and - for each channel).  This is a very significant difference and has a lot to do with how you should hook up the subs, and so I can't give you a straight answer as to whether or not you have them hooked up "right" or "wrong".

What is the brand and model number of your amplifier?  And what about your subs (including voice coil impedence)?  If you give us that info I can figure out the best way to hook them up to your amp.

The first diagram is parallel and the 2nd is series. You can read about the differences here https://www.eatel.net/~amptech/elecdisc/srsparll.htm but the only reason you wire it one way or the other is for the load on the amp.

My main point was that without specifics such as the model number of the amp, and the subs' voice coil impedence, it's kind of like comparing apples and oranges.  Because according to his drawing, his amp appears to be a single channel amp, but the amp in the alpine example appears to be a 2 channel amp.

OK..the AMP is the same..its a 2 channel AMP. (L -, L+, R-, R+) ok. I took my subs out and they are EACH 4ohms + 4 ohms on the back of the sub. SOO, which would be the BEST way to hook them up to my amp? The first diagram or the second?
