[QUOTE="wickedwitt, post: 8059059, member: 622908"] An isolator is not necessary if you are charging them to the same voltage (ex. both 12v batteries). As long as the 8s and 12s are truly crossed over to be playing different frequencies, that would be acceptable. Decently amped mid speakers should handle this just fine, however. The 8s in this scenario are really inane. I don't have the time to fully explain cancellation to you, hopefully someone will chime in. Essentially, the varying characteristics of the two different drivers, on differing power, in different enclosures means the sound waves produced by them will cancel each other out. What this means to you is a muffled sound, and less output by having both than if you say just had the 12s. In all honesty, I wouldn't do the 8s at all and would save the money from that part of the system to upgrade to a bit bigger mono and run R2 12s in a decent ported box. Crossover the R2s at 63hz Low-Pass Filter, then cross your mids at 80 High-Pass Filter. They should meet up quite well giving you full range from the lower end of your subs response (20-30hz depending on box tuning, size, and power) all the way up to 20k (the upper limits of human hearing).
