Adding 2nd battery today

I am going to run the second battery for my amps in the trunk, will this make the subs hit harder, or sound better? Will this act as a power cap, or will this just put strain on my altinator? is this a good idea, or bad idea , any answers?

you can use a little thing i forget the name but it allows you to have power flow one way so the second battery charges the stock on or something like that

I added the batery a few days ago now with no problems, both batteries remain charged equaly, and no dimming of any lights, and no signs of power loss, this was a really good idea, I didn't even need an isolator,
Is my car draining juice from the 2nd battery in my trunk, for the headlights etc.. ? or is that power from the 2nd battery only going to my subs, and amp?
I checked both battreries with a multi-meter and they both read 12.35, you think this is gunna be hard on my altinator?
