Adding Car Audio Battery
I want to add a second battery in my trunk to run my amps. Does anyone have a website for info. like this? A diagram would be very helpful. I spend 8 hrs. a day here at work searching the i-net and I can't seem to find this info. out.

im not sure how to wire up a battery in the trunk, but i believe when some charge they release gasses that need to be vented...
i might as well throw out an oposing thought, why not upgrade whats under your hood, like ordering a HO alternator for your car, and adding something like a yellowtop?

The easiest way to do it would be to plop one in the trunk (your best bet is using the same type of battery as what you have under the hood so they charge evenly) and just connect it to your main battery + to + and - to -. I don't think you'll have to worry about venting a sealed deep cycle battery.

I would agree somewhat with zinger. Unless you are running your system with the car off a lot, your alternator is what needs upgrading the most, along with the big 3.
If you have the coin to spend, adding a 2nd battery will always let you handle more, but, if its not your weakest link, then put your money elsewhere.
Also for a second battery, look into an isolator or solenoid between the two batteries. It keeps your car stereo from touching the juice in your car's battery, as they don't generally cycle well. (Every time they recharge they lose capacity)

This is true, an alternator sounds like a better upgrade in your case, but if you're adament on adding a battery then you should probably replace the one under the hood with the same deep cycle as well. Done in this manner, I don't think you'd need an isolator since you would be able to discharge both batteries without worrying about wrecking them.
