- Q: My car's stock stereo is pretty low power, probably less than 20 watts. I would like to replace the power wires with better ones, if not for any real benefit to sound quality then simply to satisfy a personal whim. 8 gauge wires would be too I think for the small spaces. Anyway, would a good quality speaker wire work just a good as a power wire of the same gauge?
- I trust DJ. additionally you are able to try your subs with a volt meter. turn the meter to ohm mode and touch the finally leads to your subwoofer pos. and neg. (it incredibly is unhooked from the amp). this promises you a analyzing which could be a mild one million,2,4,6, or maybe 8. If the extensive style bounces around ANY, then your subs are broken. you are able to basically be working 4 ohm whilst your amp is one million ohm reliable or some thing. in line with threat try rewiring your subs too when you do the flexibility. The decrease your speaker ohm load, the greater watts you get out of your amp. warning**** do no longer go below the cautioned ohm load of you amp. it's going to capture fire or blow fuses once you're fortunate.
- Q: I have a power adapter that goes to a mixer (Denon DN-MC6000) and reads: INPUT 100-240V ~ 50/60Hz 1.5A, OUTPUT: 12V - 3A. Now I know this is the right adapter but I don't know if I have the right cable that goes from the adapter to the wall. I have one that says 6A 250V~ but I dunno if its the right one. I have a few others but can someone tell me what will be the right one so I don't blow up my mixer :P thanks
- This type of power cable can be plugged into any household power between 100 and 240 volts. So, any plug that fits into the wall plug is the right one. In the US and Canada the voltage is 110-120 volts. In the rest of the world 240 volts are used The plug and wire you mention is for the rest of the world. Now look at the adapter where you plug the cable into. Do they fit together? If yes go for it. If not keep looking.
- Q: I have an electrical source 220 Kv or 380 KV at site X and want to pull cables to site Y to privde electricity for this Y site for general lighting and power sockets.So what is the max distance for the cables i can pull from site X without voltage drop affect the voltage or power at site Y.
- You are not providing enough information. 220 KV can provide power of TENS of miles on reasonably modest cable PROVIDING the current drain is not too high. Sorry but the idea of anyone playing around with almost .4 MV without the first idea about loading / cable diameter / insualtion requirements scares the crap out of me! Without the required information, all I can say is With the right cable at 380KV , hundreds of miles As an aside, if this is a temorary site, then the cost of buying generator will be WAY cheaper than the cost of the cable and transformers you wil require to turn 380Kv into 110 / 220V If a permenent fixture, then suggest for normal lighting and sockets (as in no industrial smelting plants!), then you would eed to be dropping the voltage either at the 380kv site OR at least some distance from the new fixture. Houses do not typically have .4 MV coming into the cellar. It might arc a few metres you see if the air is a little humid. Make things a bit dodgy. **UPDATE** Ok, thanks for clarifying the voltage. Now we also know power too -so at 220v, and about 12KW we are looking at VERY roughly 55 Amps. 25mm cable ought to be good for a couple of hundred metres or so. 16mm for upto 50 metres or so. If a LOT further than that, then either go with three phase/380 OR up the size of the cable. Problem is it can start getting pricey. The shorter the run, the lighter the cable can be - to a point - would NOT suggest going below 10mm under ANY circumstances. You will always get SOME voltage drop, but providing it is in the order of a couple of volts here and there, there is no appreciable waste / heat generation. Is this a fixed installation or a temporary one - if temporary and a fair distance away I would STILL be inclined to sugges a genset hire might work out cheaper than drums of suitable cable.
- Q: Do you need to use both the 6 pin PCI-E power cable and the 8 pin PCI-E power cable on a video card? Why are they used? To give power to the video card if needed? Seems like the motherboard gives the card power as well?
- Different cards have different power requirements. Yes, you need to connect all of the power cables. For example the Radeon 5770 has only a single 6-pin connector and runs fine on a 450W power supply, while the Radeon 4870 and GTX 250 require two power connectors from 500-550W (or higher) psu. Cards draw some power directly from the slot (They can draw more under PCI-E 2.0 and later than version 1.1 or 1.0)
- Q: everything was working great! and then i blew the main fuse! i replaced it everything was fine after that but then out of nowhere i only have power in half of the power cable connected to the amp!! What can i do??
- I okorder /... Under the column for 90 degree cable in copper pick the wire gauge that is closest to your amp requirements without being under. For example: 1200 watt amp = 100 amps of power 2 gauge copper can handle 130 amps (This chart is missing 3 gauge which some places do carry, which can handle 110 amps) 4 gauge is only good for 95 amps. These ratings are about heat build up from inductance of the current. When the heat exceeds the rating, the sheathing melts and conductor degrades at it's weakest point. I recommend use of THHN electrical wire. It is gas and oil resistant and has heavy strands that hold up well to the stress of vehicle install situations. If your wire and fuses are properly sized, then check all of your connections. Often times heat and vibration will loosen screws on amplifier contacts. Also, under the hood, heat can melt your fuse holder causing plastic to coat the contact points (in which case you'll need a small file to clean the contacts) There's really a lot of possibilities here and your question is quite vague and convoluted. Please give more details or take some time and analyse the problem carefully. Chances are that you will discover the source of the problem in a matter of just 15 minutes or so of checking.
- Q: Im looking for a sata cable that has one connector to the mother board and splits in two to connectors for to two HDD's (just like the old IDE cables )IM NOT LOOKING FOR THE POWER CABLE IM LOOKING FOR THE DATA CABLEdo you know were i can find one please give link were i can buy or tutorial were i can make my own

- Q: Can i leave my laptop on the whole day and just turn it off at night? It has a standby mode but i dont no if thats resourceful. Also it has sleep and hibernate. Will leaving the power cord in be bad?
- No need to leave it plug in all night. You can do it the simple way and shut it down for the night. As for myself, I put mine to sleep during the night (unplugged of course) and causes me no problems.. but if you are unsure on what to do, just shut it down during the night and no harm will be done.
- Q: So I had this monitor I used to use, then didn't use it for a while, now I want to use it again but can't find the power supply cable. I can get a new one, but the thing is I have to know what to ask for, right? I don't know what cable to ask for. I did some google search on it too but still can't seem to find exactly the type of the cable that is specified. Help? Can someone do it for me so I can go to my local electronics score and look for a cable that will do the work?
- unerversal 3 prong power chord for pc
- Q: Help in English:do these expressions have exactly the same meaning?
- A cable is usually thicker than a cord. When I hear power cable, I tend to think of industrial machinery.
- Q: I have Windows Vista on my Asus W2P laptop and I have had this weird problem for a while - every time I plug the power cable in when the computer is actually on, Media Centre automatically starts. It's not really an issue, except that it's a bit annoying and weird!! Has anyone else had/heard of an issue lke this?
- Use windows defender hit softwares tab and remove windows media center from startup programs list
