I won't comment on the isolator because so many people argue on that. However, skip the batcap, it's not going to do much for helping out electrical problems (assuming that's what you have). What the Big 3 does is it increases the efficiency of your electrical system. There is a sticky on it.

if you have electrical problems, just do the big 3 (sticky in wire forum) then upgrade alt, and make sure you have proper sized power wire for your amps. batterys and caps are just a waste for a daily driver. i run at a constant 14.5 volts at my amps and have no expensive batteries or caps
