I currently have an OPtima yellow top. It is 12 volt, if I'm not mistaken. What are some good 14-16 volt batteries. I am hoping get a little extra out of my system. Also, can higher voltage batteries hurt the rest of the car in any way?

I'm not sure where you live but I'm sure you have a Batteries plus or a farm parts store around you. If not call around and find out where they sell 6 volt and 8 volt batteries. Not the small ones though. Run them in Parallel if I'm not mistaken and that will give you a 14 volt load. Anything higher you proably won't want to get into though. Just more problems can arise from such a high voltage.

You can run the Exide #3600 6v and the #4800 8v batteries in series. This will give you the desired 14.4v but will limit the current of the pair to 1000cca. (the batteries are 1000cca ea. at their respected voltages.)
parallel wiring = Connect the "+" to "+" and "-" to "-". adds cold cranking amps's but voltage remains the same. (2 12v 1000cca batteries in parallel would give you 12v at 2000cca.)
series wiring = Connect the "+" of one battery to the "-" of the 2nd battery, then use the REMAINING "+" and "-" to hook up the electronics as normal. This add's voltages but cold craking amp's stays the same. (2 12v 1000cca batteries in series would give you 24v at 1000cca.)
IF IN DOUBT SEEK PROFESIONAL HELP!!!!!
Most altenator shops or battery dealers can help you.

Would isolating another battery in the rear help my voltage. I usually stay around 12.5 with the system on. I am hoping to get that up to 14. I also have the Alumapro 15 farad CAP in there, if that affects anything.

the only ways to increase voltage is to use higher voltage batteries and adjust your voltage regulator. If your alt can keep up with your system, you can just increase the alt voltage and stay 12v. From what you have said this is not the case as you drop below the 12.6v that a 12v batt actually produces.

Here is the problem with 14 or 16 volt systems first of all your alt. cannot charge either of these systems effectivly even a 14 volt system needs between 15.5 and 16 volts to charge. and the 16 needs even more. call the amplifier manufacter to find out what kind of voltage they can handle. most amps cannot handle a 16 volt system charged (17.2 volts)and YES get the small batteries they discharge faster.
