I used to work at circuit city and behind the display wall is 4 or 5 computers that run the entire show, and all those amplifiers and subs are all powered by huge DC power supplies that can put out 100+ Amps constant.
Ive tried making one, Ive tried finding one, But i can get a hold of one.
Does anyone know where i can get such a DC Power supply that i could plug into the wall at my house and then run a car amp/subs off it?
Cause id love to get 4 infinity's to go with my 1210a amp
ive looked there, but they have nothing close to the Supplies they got at circit city. There is a electronic supply store where i live called You-Do-It-Electronics and they didnt have anything close
yes im gona walk into C City and go behind the display by knocking over the subwoofers to get to the secret door and then walk out with a 200lb black thing the size of small filing cabinent
Why not just make a bank of Optima Yellow Tops (deep cycle sealed batteries), and a charger.
You're probably not going to run the system for hours and hours, so it only needs to last a short time.
Plus you can always re-use the batteries in a big system if you decide to get rid of the display.
I have 2 optimas on a trickle charger in my home, I use a Soundstream Reference 1000s car amp on a pair of home subwoofers. I have the charger hooked up so that it charges them when I'm not using the system.
May I ask why you would want to do this? If you already own the amps/subs and just want to use them at home I can understand. Otherwise...
You would be much better off just buying a home receiver/amp from BB or CC to drive the subs. Or you could look at the used market for home amps. Audiogon is a place to start. Then of course there is eBay.
Of course for a home system you would be better off with home components / speakers / subs. Car equipment typically doesn't fare too well in a home environment (exceptions to higher-end stuff of course). I tried using a sub-box at home once. It sounded like arse.
A final note: Any power supply that could adequately drive the amps would most likely require a dedicated 15 amp circuit minimum. The approach with batteries and a separate charger seems to be the best route.
I have a JVC 7.1 700w Home Theater Reciver, With 7 Sony Speakers incuding 5 ft tall floor speakers. I have a KLH 12" 150w Home subwoofer.
My point is that i want more subs in my room, but home powerd subs are expensive, Its cheaper to buy car subwoofers and they are much louder than home subs. So i just want to get some of those so i can have 2 12" subs in my room.
If it is a large room (18' x 18' or more) I can see the desire/need, otherwise I don't get it.
I personally would recommend another powered sub, and have one in each corner. Make sure everything's in phase, or some/much of the bass will be canceled out.
I just can't recommend using car subs/boxes in a home system. They're just not going to sound that good.
By "good" sound I'm referring to smooth frequency response, balanced appropriately with the rest of the audio spectrum.
If you're after the "one note bass" sound that seems to be popular, then I'd go ahead and use the car subs, but still use a home amp to drive them (but get a really powerful one, DJ equipment would work well here).
you don't need to have such a large power supply to power a sub in your house
just use a computer power supply.....you don't even need a constant power supply, though if you really want peak efficiency, you can splurge on one
after that, it's really just matching an efficient amp to a good quality sub with a well tuned box
my buddy has about 100w rms running through a bridged 2ch a/b amp to a ported 12" polk and it shakes the house no problem even with a non-constant power supply which he picked up for 15bucks at a computer shop
