How to use sub/amp in house application?
I have spare subs and amps and boxes here from prior systems that I want to
put to use. I want to hook a sub and amp to my computer for bass for music. Now, I have the line out with RCA's already to plug in to the amp, my problem is how do I power and ground an amp in an indoor application? The amp I would use has a 30amp draw or so. I know I would need an invertor. Radioshack had a big bulky inverter, 10amps juice and was $80. There must be an easier and better way to do this. Can anyone make any suggestions? Brian |

Brian if you want to do it correctly.. about the only thing you can use from what you have are the subs. more than likely the enclosures you have will be too small for home use. and using car amps can be messy to use in the home.. as far as wiring goes. parts express has a sub amp for about the same price as that inverter. but if you just want something there.. i've used an old r/c car battery charger i had lying around to test and use car amps in the home. hth, -- cyrus |

Think about this, then do some research: Why are amps so big? Why to the
get so hot? The first half of an amp is used to condition the electricity, or in other words, convert it to alternating current, as you know, the power that comes out of your wall is also alternating, if you cut a couple coils and get some resistors, you will be able to hook your car amp up to AC with no problems. -- ocran ------------------------------------------------------------------------ CarAudioForum.com - Usenet Gateway w/over one million posts online!

How about if I was to plug that in to a wall via the adaptor, as if charging the unit... then simply crunch my amps power and ground wires between the charger / power units gator jaws. That should provide it with the 12V that it would need, and keep the power flowing from a wall outlet. Then throw some rubber around the jaws to keep the wires from shorting on eachother/anything. This sounds like it might be doable. Any big problems with this? Brian heh.. sure it might work, probably not the best idea though. -- cyrus |

Why not go out and buy some type of battery (motorcycle, car, or riding lawn mower) and hook it up between the charger and the amp?

You can tap a DC power supply into the amp to skip its power inverter. Most likely it's in the area of +/- 35 volts unregulated. It's not a great idea, though. Car audio equipment often has inferior sound quality compared to home audio equipment. Most of a car sound system's cost goes into the power inverter and its compact size, both of which are unnecessary in home use. |

Um...for all the money this would cost, why not just buy a home amplifier?
Hell, even most pawn shops that sell electronic equipment have old amplifiers for under a hundred... -- Mark Zarella zarellam at upstate dot edu "Sam Carleton" wrote in message ...

How to use sub/amp in house application?
Two big problems with simply charging your battery indoors during use.
1. Possibility of overcharge of the battery and consequent leakage or explosion 2. The production of hydrogen gas in the house as the alkaline battery charges Best thing to do is to get a home audio amplifier than can operate at the impedance your speakers need... n8 Thanks for the post!

How to use sub/amp in house application?
I second the vote for a parts express subwoofer amp. They are REALLY
well made, and are excellent on a watt/dollar basis. My brother bought one for a home theater project using a kappa perfect 12" sub. Sounds SOLID. IMHO blows away other high end home subs at a fraction of the cost. The amp was around $125 and the sub was an extra from his car audio system. I dont think a car battery in the house is the safest thing. There have been threads/discussions on battery explosions and fires before. IMHO you should read those threads first before going this route. A bench power supply would work but IMHO the wire bundles and such would be messy.
