I want to run them in my house off AC current. I've been looking at using this DC powersupply http://www.audioclubhouse.com/proddetail.php?prod=PS52KX Will this suffice? Or will I need a capacitor? A more powerfull PS? Comments pls? |

That model should be alright for home use/testing. If you need more power, the car battery starter/charger can easily work just as well. In fact, it should be cheaper and give more power. My charger is 65A continous and cost around $125 US. |

Gold Member Username: CarguyPost Number: 4357 Registered: Nov-04 | You don't need a car battery, but if you plan on using it often, a deepcycle wouldn't hurt. A heavy duty car starter/charger will give 200A - 225A and 65A continuous. This is enough to power most amps. If you are planning to get a battery, have a look at Yellowtop. It doesn't emit gases. The charger runs off ac. |

They will have a tendency to burn out when using them in your application, but they're cheap enough to make it worth replacing. They're also helpful if you have a tendency for leaving your headlights on all night (d'oh!) |

New member Username: Ww_daggerVancouver, WA USA Post Number: 3 Registered: Sep-05 | I found a DC power supply that just might do the trick. It's an Astron with variable voltage, 70 amp peak, 57 amp continuous, with volt and amp meters. What do you think? The Pheonix Gold website says my MS2125 amp running at maximum non distorted volume can draw 65 amps cont. and 100amps peak... This supply is just shy of that. Opinions?? |

Platinum Member Username: GlasswolfWisteria, Lane USA Post Number: 10510 Registered: Dec-03 | damn you and your logic, man! actually that power supply should be fine.. I meant if he tried to use a battery and a battery charger.. great way to have an accident and set off sparks that set a carpet on fire or something.. all it takes is a careless dog or a cat, or a shoe tripping over a cord. |

New member Username: Ww_daggerVancouver, WA USA Post Number: 5 Registered: Sep-05 | I've found power supplies that are "Linear" and "Switching". I don't understand the difference. Which of these would I need, or would eaither work? This is the linear supply I found: http://store.solar-electric.com/iotdl12volba.html |

Platinum Member Username: GlasswolfWisteria, Lane USA Post Number: 10520 Registered: Dec-03 | you need a regulated switching AC to DC power supply, and go by the continuous current ratings, not peak when picking out the one you want. peak doesn't matter with an amplifier.. you need to know how much current the supply can give all the time. |
