It actually does look quite sweet but at least it would take care of any interference (ripples) in the power. In the long run how will it affect the system?
Thanks

short run no real problems at all. long run can present you with a knackered cap/battery and worse case- an alternator as well.
In real terms 1 Farad is next to nothing in the time it takes to discharge. Think of it this way the cap stores power which is provided through the alternator charge, once the cap discharges (which is normally within a couple of seconds- if that) it then has to pull that power to "store up" again from the alternator.
This means your alternator is working double time to charge the battery, the cap AND run the electrics in the car itself.
Caps look nice- but their usage in real life applications are very limited- I have had conversations with plenty of industry pro's who disregard them altogether and me personally I have never got on with caps either!
There are some people who beleive however that in a small low power SQ system (say between 200-300 watts RMS) that a cap can increase responsiveness in subwoofer performance, I must admit whilst I have my doubts with this appllication, I have never tried it in this particular way so I cant comment
for the money though, Its far far more effective to go for a split charge system (split charge relay- £20, heavy duty diesel/dry cell battery £70/£150 respectively) Given the average cost of a cap is anything between £60-£160 it works out roughly the same cost wise but the performance benefits are far far greater.
oh and charge comparison?
average cap= 1-5 farads
BatCAP(cross between battery and cap) = 80-400 farads
dry cell battery.....lots and lots of farads
bsodmike you've done the work already and looks smart as hell so for now at least i would keep it- but in the long run if you get electrical problems, rip it out, upgrade the "big 3 cables" (battery to alternator, alternator to chassis, battery to chassis) and put in a split charge.
then you will notice a HUGE difference in the way your system responds.
