Dusty,
A better way to wire the speakers is to run the neg from the amp to the neg on speaker 1, the pos from the amp to the pos of speaker 2, then connect the negs of speakers 1 & 2 together, and the pos of speakers 1 & 2 together. This still presents a 2 ohm load to the amp, and you avoid all the splicing work making for a cleaner install and less signal loss. Below is a sketch (I'm not the Paint expert that you are :) )
This is also how you should wire your DVC sub. Just treat each voice coil like a separate speaker and wire it as shown in my little sketch.
This also applies to the in boat speakers where you are wiring two speakers per channel.
Also, below is a link that I found to be very informative and I think you will too.
