Capacitor or beefed up alternator?
So with the new system, now I have the problem of dimming headlights and what not when the sub is turned up...should I get a capacitor or should I beef up to a higher output alternator? Does anyone know what the stock alternator puts out on a 04 Edge v6 4.0L? My roomate says to go to an alternator shop and get it 'wrapped' with extra copper or something to increase the output. Any one familiar with this?

Both are useful, but like in engines -- "there's no replacement for displacement". Meaning you need a power source that can handle the load.
That said, a capacitor can significantly reduce the apparent impedance of the source which is of benefit particularly with bass impulses. You do your best to make good wiring feeds but there is always some residual resistance and a cap can help "solidify" the power at the consumption end for intermittent loads.

I believe we have 95 amp alternators but somebody can correct me if I'm wrong. Definately agree with the above, caps are more like bandaids. They still have the purpose of stability so they are still useful. HO alternator is your best bet. Buy 2 and send one my way when you get around to it.

My solution was to calculate the size pulley needed that would be smaller than the one I had, but wouldn't result in over-spinning the alternator. As it turns out, that happened to be the smallest pulley I could find anyway. It helped.
If you have an underdrive pulley on your crankshaft, then the problem is compounded.
My amperage requirements are because of a winch, but I also have a second battery, switching system, and a solar charger to keep the second battery at "peak" while "offline" from the main charging system. This way, it offers the ability to be a "self jump start" power source.
