    Icon32 How to wire a system in my house

    I am trying to wire up a 12"polk audio sub with a brand new blue series pyramid 2 channel amp. 300w each or 6oow branched. How do I do it and what type of power converter do i need (how many amperes), or can I use a car battery with a charger.

    600 watts at 12 volts needs 50 amps. At 60% efficiency you're talking 90 amps. That's a big-*** power supply and it'll be hard to find one that big. A car battery would go dead in 20 minutes. You need a battery and a realy big charger (the equivalent of a 100 amp alternator).

    You'll also get 60 cycle or 120 cycle hum because battery chargers are unfiltered and unregulated. Car alternators are 3-phase and have very little AC ripple, battery chargers are not. The hum will drive you nuts.

    Do you happen to know of any other way I can do this. I don't think I will be using all 600 watts. I think I am just going to use the 300 watts for now, because I don't know how many watts the sub is. People told me it will between 3-400 watts. If you know, please tell me. It is a 12" polk audio sub. It is a DX12 series. That is really all I know about it. Can I use one of those caps in my home to help power it. If so what kind. (New to this audio stuff)

    No. You need a regulated 12 volt power supply. Radio shack used to have a 120 watt unit (10 amps) but I don't see it in their web site. A 53 amp unit (600 watts) can be had from Kepco for $650. Buy a stereo, it's cheaper.

    Go here if you're serious: http://www.kepco.com/rkwmod.htm

    YOu need a 13v power supply
    Pyramid makes a bunch of them

    They're big and hot, but if you want to be safe and still run your ****, its the only way

    WIht like a 100 watt amp you can run it on a little DC converter, but it will blow before to long. But above that, you simply need to buy a power suply
