Hey, I currently have a single 500 watt amp and sub in my car and I am thinking of adding another 800 watt amp for two Sony 400 watt 4-way 6x9's in the back, but I am thinking this might be too much power draw on my alternator! I found a formula that is supposed to estimate the current draw and I came up wih 188 amps! So I am wondering how to go about including a capacitor, as well how should I run the power wires from the distribution block? How far should I bring 4 ga wire into the car before splitting to 8? Should I go right back to the amps and then split or is it ok to split under the dash and come back with two wires? Also (sorry there are a few questions here) my HU has a sub-out which my amp is on now, as well as front pre-outs. But my amplifier also has an output, so would it be better to connect directly to the HU or chain the two amps together? And is it fine to use the power antenna lead for the turn-on for the second amp? (b/c my current amp is using the amp turn-on lead.) Thanks so much if anyone has some suggestions that would be great!

first off, what amps are you using that are "500 and 800 watts"
second, is there a specific reason why you are putting 800 watts to sony 6x9s? usually there isnt much need for that much power, especially for rear fill speakers.
if you are truly using 1300 watts of power, yes that is too much draw on your alternator and a cap will only make the problem worse. if you are really going to beef up your charging system you need a bigger alternator. but before we get into that we really need to know exactly what amps you are using and the exact specs on these amps.
you would not want to run preouts from your sub amp to your rear amp, there is a reason that there are separate outputs on the Head Unit.
if you are using two amps, you can also use a splice connector for your "amp turn-on lead" and just run both amps off of the same lead.
