So I'm not getting my stuff installed until April 21st which is killing me cause I really wanna check my headunit and just mess around with it. Its a Kenwood DDX812. Is there anyway that I can power it with it in my house. Any help would be appreciated.

use your car battery, or a battery charger, or a radio shack 12 volt power supply

 

You can use a car battery and hook up the 12+, Ign, and Gnd.

 

It’s always a good idea to bench-test your equipment before doing the installation. That way you know it’s working before doing a lot of work. And, if it’s working before the installation, but not working after installation; at least you know you have working components and the problem is the installation and not the devices.

As Sean mentions, you could simply use a 12v battery (not great since it will run down during your tests) or one of those battery chargers with its own self-contained battery (plugs into a household outlet and continuously charges the self-contained battery so it maintains power and never dies or loses power during your testing). You should be aware that using either of these won’t provide any protection if you connect your devices incorrectly so be use to ground everything correctly and in the right order to avoid damaging your equipment. These power sources are always “hot.”

Sean’s other suggestion, a household to DC converter, is the best way to test your equipment. Here are a couple examples of these devices:
