Q:hello,i have lots of 8 gauge wire resting at my closet. And i'm very interested on doing the big 3 upgrade to my 2000 mitsubishi eclipse gt. May i see any improvement with 8 gauge wire?...i know that at least 4 gauge is recommended...but i dont want to spend money.

4 gauge? LOL Go big or go home. 1/0 gauge or it didn't happen.

Q:i have an amp (sony xm 2002gtr) that says it requires 4 gauge wire..but they cost $100+ and i have plenty of 8 gauge wires. can i use two 8 gauge wires as a substitute for one 4 gauge wire?and also, i have my capacitor grounded to unpainted metal of my car AND the ground port of my amp..is that incorrect?

Two 8-gauge wires combined are equal to a 5-gauge wire, but that should be close enough for that amp. Make sure each wire has its own fuse near the battery; 40-amp fuses would be a good choice. If you capacitor is connected to ground, and your amp is grounded, then you don't really need a wire between the capacitor's ground terminal and the amp's ground terminal. It doesn't hurt anything, though. If the only ground wire at the amp is the one that runs to the capacitor, then you're better off connecting the amp ground directly to chassis metal.

Q:cat chewed two wires computer speaker wireand wii sensor bar wire well i can't just buy new ones or replace the wire so i need to reconnect them some how using insulated ferrules and electric tape and wire strippers any suggestions how to do this properly do i crimp them together with insulated ferrules or solder them together?what else can i do?i'm clueless how this worksneed help

The wire nut option would work but wouldn't look the best. I would go to your local hardware store and get a butt connector and some shrink tubing. Slide the shrink tube over the wire. Then place each end of your wire into the butt connector(be sure to remove appr. 3/8 of insulation). Crimp the connector onto the wire. Slide the shrink tubing to cover the connector and heat with lighter. This will give a smooth, finished look. Much cleaner than tape.

Q:Im replacing the factory rear speakers in my car but cant figure on which wires are positive and which are negative. I went on a site for impalas but the color wires they have listed are not the same color wires in my car your help will be appreciated.

your positive is always going to be the lighter color or the one with the stripe running down it

Q:Who sells just 4 gauge power and ground wire so I can do the big 3 upgrade?

You okorder /... It's also available with black insulation and in 2 gauge. Parts Express also sells appropriate ring terminals.

Q:u said when i buy a jvc wiring harness one end plugs in the back of cd player and the wires coming out of that connect to the wires in car will they be the same color though? right now there is a harness already on the cd player and the wires are on it and they are pretty long i thought i just wire those wires from it to the ones in car but they diff. colors

Do you have a wiring diagram for your car? In there, they have the color codes for the speakers, dash illumination ( so when you change the lighting on your dash, your radio will change too), power attena, constant power for the clock and presets. If you don't have the diagram, check online for it. If you bought your deck from crutchfield, they include plugs that fit your car so you dont have to cut wires. Good lluck with it.

Q:2.4) A wire has a resistance of 19.2 . It is melted down, and from the same volume of metal a new wire is made that is 5 times longer than the original wire. What is the resistance of the new wire?

the quantity of twine ought to stay the comparable that's A L, so once you double L you decrease A in 0.5. Resistance = Rho L/A, so the recent twine has 4 cases the resistance or 20 ohms.

Q:I don't like wiring nuts because I always feel like it's not a solid connection, like it could come out.

Install the wire nut then pull on each wire to check that it is secure. there are alternate approved devices to connect wires. Crimp connectors like butt splices, split bolts, terminal strips. Any or all of these might be used in a situation.

Q:what size of wire do i need and is the new fuse box/trip box kept in garage.or where can i get wiring diagrams from

Depends if you plan on running welder or welders,lights of course and an air compressors,you requir 220 to 240 volts,the breaker box should be in your garage,now go to the welding store,or tractor supply and get 10 gauge wire,might as well get a small spool of it cause you're gonna need it,depending on the size of your garage,i own my own auto body shop and my 8 employes are either welding or running the air compresers to shoot a car,now my shop can hold 6 cars maximum inside,others stay out side,+ they're under constant survalance watch,along with the shop and my office,so theres more power being drawn there to,my electric bill is around $1,900 a month,give or take,find someone that knows what they are doing a bit with electrical work,a buddy or something,it's hard to say what it would cost with not knowing what your garage will be used to do.

Q:I wired an outdoor lamp-post. I tested it before wiring it to the fuse box...and if I touch the lamp-post I feel the current (a slight shock). I will be using a ground fault breaker....so I assume if I wire it to that I am going to loose the connection. Any thoughts on what is wrong?

You likely scratched the wire somewhere. When I did an outdoor shed the wire made a corner on some metal and scratched the insulation. It is a leak rather than hooking up the wrong wire, otherwise you would have gotten more than a tingle. First I would examine everywhere the wire comes in contact with the post. Second Check all the connections to see if some were improperly taped, or the wire was cut when stripping.
