Q:im installing a JVC raido in my 1990 nissan maxima and cant figure out how to properly conect the wires

The easiest way to install the head unit is to buy the harness adapter that's for your car and match the colors of the harness adapter to the head unit wiring harness. An antenna adapter will also be needed for the new head unit. A dash kit will obvious will be needed to make the installation seamless.

Q:I have two white wires left...one is a speaker wire and the other is the constant 12v wire and I don't know which is which. They are the same thickness so unless one of you guys know I'm pretty much screwed here. Also, I have a black ground wire sticking out of the wiring harness and the ground wire from my stereo harness doesn't look like they should attach to each other. This is my first install and I've got everything else hooked up. Just need some pointers.

Q:friend i want litz wire in this wire consits of group of enamled coted copper wire(like machine winding wire with multi lead wire),so i want types different guages(that each lead in wiretotal wire guage) and no of leadds.my pupose is for project wire for with standing wire capcity of 20amp's. please give information............................

20 amps is a lot. Litz wire's advantage is for use at RF frequencies, since RF current flows on the surface of the wire mostly. Linz wire because of the large number of strands, conducts RF much better that ordinary stranded wire or solid. Litz 175/40, 175 strands of #40, sells for $15 for 75 feet. #40 is 1.07 ohms per foot dividing by 175, that is 0.006 ohms per foot, about #18, which would not carry 20 amps. Ref has more sizes.

Q:I have 12/3 wire running from the breaker box on a 20 amp breaker that powers a bathroom (2 lights and 2 receptacles). I want to splice into this and run 14/2 wire into the living room to run 6 recessed lights. Is this OK to do?

No, you can't extend a 20A circuit with 14 G wire. And you can't legally downgrade the existing 12 G wire circuit to a 15 A breaker. And you can't put two wires into a single breaker inside the panel. Fastest solution? Almost all brands of panel offer a two breakers in one slot or high density option. So you can get a new thing that fits in the space of one 15A breaker but has two breakers in it and two connection screws on it. Replace an existing 15A breaker with a high density 15/15 and hook up two 15A circuits. These are also available in unequal configurations - so you could get one that had a 15A and a 20A breaker in the space of a single 'normal' 15 or 20 A breaker. In some brands these high density breakers only fit in certain (closer to the mains connection) spaces - typically the top 15 or 20 breaker spaces. Slower solution. That 15 A breaker that you wanted to put two wires on? Follow the wire from it into the attic, cut it, put in a junction box and splice your new 14 G wire in there. Then again, what else is on that circuit and will 15 A supply it all?

Q:i have my wires installed by a professional, and i wanted to put an taco switch to run to my amp, if i run a taco switch will it be okay? and with messing up the wires that he already ran would it screw it up?

Are you wanting to listen to your stereo with your Sub off sometimes? There would be no problem putting a in-line toggle switch on your REM wire. Just look at the color of the small wire going into your amp, then find that wire under the dash. Cut the wire and strip both ends. Connect one side of the toggle to one wire and the other side to the toggle to the other wire . Now it is just a In-line switch. mount it where you want Turning this off and on wont hurt your amp.

Q:On a 1985 Dodge D-250 there are two wires coming off of the starter the thicker off the two goes two the starter the smaller one has been cut up by the battery. I was told the truck was running last week and all they were doing to start it was touching it to the positive post with the other wire but when I do this the starter just clicks. I pulled the starter and had it tested and was told its good and I have power to the cab I.e. lights and all so were does this wire go and what do I need to do to start this thing

Sounds like it may have a temporarily weak battery. Hook it up to a charger overnight or get a jump off someone. If manual transmission, you could try a push start and just let the alternator charge the battery while you drive around.

Q:Ok. so i wired my cd deck into my 92 buick, but everytime i start the car i have to manually turn on the cd deck. i also have to change the settings everytime! and once i turn off the car the setting will not save and the setting will be lost. Now everytime i turn my car on i have to manually put the settings again! this did not happen in my old car! and i think it might be the wiring! Because the last cd deck i had did save the settings! and would turn thge cd player on everytime i turned on my car!! and it would play the track back, right where i left off. please help! i did attach the yellow cable wire the red cable to the battery current.? is there a problem!

You should have the yellow power wire connected to constant power and the red wired to ACC. You don't and this is why it's bahiving the way it is.

Q:The wire from the pinball machine only has two wires. How do I rewire the machine with a grounded wire and plug?

Just go to your home cente or electric supply house, and get as long as you need of 16/3 SJO or SJTW cord and a grounded plug, and replace the cord there.

Q:when installing two subwoofers to an amp, can just normal speaker wires work or do I need any special wires to hook the subs to the amp?

speaker wires will do just fine

Q:On what actually does ampere depends, thickness of wire or number of turns of wire or what else? Electrical

Your okorder /... and get ohms/1000 ft for the size of wire you select. Also check fusing current while you are there. Eg, #30 has 105 ohms/1000'. So if you have 10' of wire, it's resistance would be 105/100 = 1.05 ohms. Once you have the resistance, use ohms law and the voltage applied to calculate current. For 12 volts, I = 12/1.05 or 11 amps. Fusing current is 10 amps (which is in the open, not in a coil) so you need more length or thicker wire. For AC, and coils, you need more complicated calculations.
