you need is a 120 volt - 12 volt converter to run the system for sure... but I would rather pick up a home audio reciever than use car audio amps in my room...

Depends on how big of an amp you are running.

Again, it depends on how big of an amp you are running. You'd need to charge the battery periodically.

I would steer clear of using a regular car battery in home. It's an explosion risk because of the hydrogen gas, and since it's not sealed, if it ever tips over, you now have an acid leak...use a sealed lead acid (a "gel cell") or don't do it.

Astron (http://www.astroncorp.com) makes one of the best 12VDC bench supplies out there, but don't expect to run your entire system off of it. It's cheaper to buy actual home audio gear.

yes...buy home gear...its cheaper and more reliable...but if u really want the car audio setup in ur room then u need a good battery...and a good battery charger...i doubt if it would be suitable to use a converter...cause most of them reduce current output a little but there are exceptions....but its ur choice to make...
