Just use it like a distribution block. To tackle dimming the right way start by figuring out the theoretical current draw of your amps by dividing their rated rms power by 14v. That would represent your approximate peak current draw at full volume, divide that by 3 to figure a reasonable long term average. If that number approaches or exceeds the current rating of your stock alternator then that may be the upgrade you need to make. If it's close to or below the current of your stock alt you can help the charging system out by adding 4 gauge wires to the 3 main charging system wires -- batt to alt (+), batt to chassis (-), and engine block to chassis (-). A cap is rarely a solution for dimming headlights. When they do solve that it's purely coincidence -- it is not what they were designed to do.<br><b>References : </b><br> you never need a capacitor, but yes you can use ONE with 2 amps.
