Don't know where to hook up little black wire in the back

If your amp has an earthing terminal on the rear panel connect it there. If not remove a turntable rca plug from your amp and sit the wire on the inside of the plug then connect back to amp. Cheers John. Styluscity

look down on the front left side of the front panel,you'll see a plastic cap,pop it off and start the dryer,when you start it listen for a click and look into the hole where you popped the plastic cap off from,if you don't see anything glowing orange inside and don't hear a click when you start it you have a bad thermal fuse part number 3392519 and it's around 15 dollars.unplug the dryer,pull it out away from the wall if it has a flex line on it for the gas,disconnect the vent line and remove the back panel,now look on the left side,you'll see the metal duct that the lint filter slides down into,look to the right of it and down low and you'll see a white part,that's the thermal fuse,if you have a volt meter check the fuse with the meter,you have to remove at least one of the wires when you check it,if you don't have a meter you can pull the two wires off,stick them together and start the dryer,look into the front hole and see if the ignitor is glowing orange and the flame lights,if it does shut it down and then you have to remove the metal duct that the filter slides into and clean it,also you have to clean out the vent line,this is why the fuse popped,the dryer got to hot and popped the fuse,you have to remove the 4 screws holding the duct on and remove the two phillips screws on top of the top panel where the lint filter is,buy the fuse and put it in,doesn't matter what wire goes where,you should clean this out once a year with gas,if your vent line is long you can blow it out with a leaf blower,remove the vent line from the back of the dryer,stick the leaf blower in it and blow it out,first go outside and make sure there isn't a cage or screen or anything blocking the air from blowing out,if there is remove it so it doesn't happen again.if the fuse is good then you have to pop off the front panel and the problem will be inside the cabinet,also while you're in there clean out the inside with a vac.let me know what you find and if you have a meter,if you don't it would be cheaper to buy one and i'll be glad to help you,

Why is there four plugs on the back of speakers?

With four plug you will have a jumper from on plug to the other. (e.g. Positive to positive and negative to negative.) This is for single connection (two wires.) If you use two connections (four wires) you take out the jumpers. the bottom pair is normally for the bass and the top for treble. This is to make the speakers clearer, and sound better. As for louder,? I don't know some people think it does some don't. With better clarity of sound, you do get the feeling of it being louder.

Fujitsu tower smoke out of rear no power

Sounds like you need a new power supply. Have a look at the labels on the old one inside the tower. The thing to look for is the total power output in Watts.
If it's 300watts for example then buy another with the same or higher wattage, I would go for a higher one. Then check the leads that come out the back in to the drives and motherboard etc. Especially the power to the motherboard. If it's a 20 pin socket thats the standard, if it's a 24 pin socket thats the more modern type but can still be used on a 20 pin connector on the motherboard, you just don't use the other 4 pin plug thats usually seperate at the end of the plug. The power supply is usually only held in place with 4 screws on the outside of the tower.
The main power connector to the motherboard has a little clip on the side of the plug that you have to press in to remove, it's like a little hook to stop it comming loose. There may also be a black and yellow wire 4 pin plug near the pocessor heatsink on fan, that also has a clip to press.It's not a hard job, just take your time and don't apply to much pressure when connecting the new leads to the board.

How to hook up the wiring on the crunch 520.5 need to know the gage for power

  • I would go with some good 8 gauge. More than that for this amp would be overkill and a waste. Many people thing thicker wire is better but that is not the case. To thick of wire to the power feed can draw to much power and send the amp into protect mode. Also to thick of wire with an insufficient amount of power can actual hamper the amps true abilities.
  • Use stranded copper wire not solid copper wire for the best results of conductivity.
  • Make sure to run a 50 amp fuse inline with the power wire right off the battery. Amps surge and it is far easier to replace a $1 fuse than components inside your amp.
  • Your ground is best served running to a bolt in the floorboard. Using the same size, style and quality as your power wire is recommended.
  • Your remote wire will connect to the remote wire running from the back of your deck. The remote wire enables your amp to shut off when your deck is shut off. A simple 16 gauge stranded copper wire will suffice for the remote wire.
  • I recommend hooking the speakers up using one speaker per channel. I don't bridge amps really. If you want more power then buy a bigger amp.
  • The AV cords will go from your deck to your amp right to right and left to left.
  • That's the way to wire your amp.

Yes, keep in mind that the amps have a constant power (the large red wire) and need a remote signal to tell them when to turn on/off. This wire connect to a switched 12v from the ignition or radio blue wire (if aftermarket)
