Yes buddy u can works great in a garage hook a car battery to a 12v power inverter commonly found on hobby websites and wire accordingly..one more tip rem goes to pos terminal.and im not sure if this is four channel amp but a dvd player will be the rca wires red and white of course but attached to a good size speaker it will crank and if u decide to use a bigger amp get a small capacitor u only need .5 farad for about every 500wrms u will need.it will help so a larger inverter wont have to be bought unless u go much bigger and if ur like me and want it done a cheap way any battery charger will work but not for long periods of time
