What kind of rear seats do you have? 60/40?

I do have 60/40... i've seen the risers, but never thought they looked very good

You can take the 40 out.

I could... but I think i'll go with the stealthbox... I want it to look as clean/stock as possible.

I understand that a cap isn't the answer for a weak battery/alternator, but my understanding of a cap is basically its able to provide the quick burst of power that your battery might not be able to due to the fact that it can discharge its power much faster than a battery (think camera flash)...

Again, if your alt is capable of handling your power needs, then a cap is useless. Think of it this way as well. If your alt is unable to handle those power bursts, then how is it going to handle having to recharge yet another item (the cap). Also, you're battery doesn't handle your stereo's power needs if the car is running.

My space is pretty limited... i'm currently looking at about a 8-9 inch verticle clearance on the high spots of my back seat, with all the supports and what not underneath them there's just not much room for a decent sub without using risers on the seat which I'd like to avoid. There also isn't anything behind the back bench as its flush with the rear of the cab. I know MTX makes the thunderform with dual 8's but that isn't my first choice.
My other option is to use the back seat and set a sub box in the seat, but I want to make it look as clean as possible and hate to give up the seat (even though its rare anyone uses it)

I know what you mean. IMO the best systems are ones you can't see. But most regular/ext cab trucks are tight on space for sub boxes. In order to even get my truck's sub box in, I had to lose the jack and it's attachments from behind the back seat and build the box slightly smaller than specs called for.

So when the car is running the power comes directly from the alternator?

Yes. Batteries store power and when the voltage drops to a certain point the batteries release energy to compensate.
