well first off your running pretty sub par run of the mill stuff. There's nothing high end about the equipment your using. And I'm not saying that to cut you down at all. It's decent stuff Just not real good stuff. which brings up the powering issue and you'll see why. All that stuff together if your lucky is going to push maybe 600watts RMS. maybe..... so your proably not going to have to invest into alot to power it properly. You optima batteries will probably just be over kill but if you got a hook up on one get it. I doubt your going to need a cap but what alt are you running??? the 85 (I think is the lower end one) or the 105? If your already running the 105 your probably already producing more than enough to run things properly. if it's the 85 you just very well may kill it and your cap might not be a bad investment. Get some decent 4 AWG power wire and 4 AWG grounds. a distrubution block and a handful of gold connectors and your system should be decent enough to hold your own :wink:
