This type of question usually means you aren't ready to do this yourself. Study some electrical material and the National Electrical Code and work this answer out for yourself, or call a professional electrician. If I were to give you an answer, you might attempt to do something you shouldn't be doing, and that may cost someone a shock, a home fire, or their life.

How do you wire a light to a switch at the end of a run and which controls an outlet?

Bring power into the light switch box 12/2 or 14/2 wire depending on the existing wire. Make sure you use the exactly same size wire that is used on that circuit. If you do not know look at the breaker in the main panel that controls power to that circuit. 20 amp will be 12/2 wire and 15 amp will be 14/2 wire. Now run another wire from the switch box out to the outlet. Inside the switch box, strip both white wires back 3/4" and connect them together under a wire nut and push this back into the box. Connect the 2 ground wires together and then connect that to the ground screw on the switch. You now have 2 black wires left. Connect them to the 2 screws on the light switch. Does not matter which black wire you connect to which screw. At the outlet connect the ground wire to the green ground screw, black wire to copper screw, and white wire to silver screw. That outlet will now be controlled by the light switch.


How do you wire a double outlet to a lightswitch?

Bring power into the switch box with a 12/2 or 14/2 wire and send power from there to the wall outlet with another 12/2 or 14/2 wire depending on the circuit. 12/2 for 20 amp and 14/2 for 15 amp circuit. You will now have 2 sets of wires in the switch box. Connect all the whites together under a wire nut and push them back into the box. Connect all the ground wires together and attach them to the green ground screw on the switch. Connect the black wire from the power source to one of the screws on the switch, does not matter which one. Then connect the black wire going to the outlet to the other screw on the switch. Put the switch back in the box and install the cover. At the wall outlet connect the ground to green ground screw, white wire to silver screw, and black wire to gold screw on one of the outlets. Run 3jumper wires from all three of those screws to the other outlet in the box. Ground to ground, black to gold, and white to silver screws. Put it in the box and install the cover.How_do_you_wire_a_outlet_to_work_from_a_light_switch

Black/White/Ground power in and the same out. Tie the incoming and outgoing white wires together under a yellow wire nut and push them back in the box. Tie the ground wires together under a green wire nut and connect the pigtail from those ground wires to the ground screw on the switch. Connect the 2 black wires you have left to the 2 screws on the switch. Doesn't matter which black wire you connect to which screw.

Can you use 40 amp breaker for your lights and plug ins?

If you are referring to house wiring then the answer is no. A breaker protects the wire size that is connected to the breaker. In home wiring most homes are wired with a #14 wire which is rated at 15 amps. That is why the wire is protected by a 15 amp breaker. The correct wire size to connect to a 40 amp breaker is a #8. This size wire is too large to connect to receptacles an light fixture terminals.

What's the best way to install a subwoofer box and amp in an Oldsmobile Alero?

If you have an after-market head unit, it will be easier. You need RCA audio cables, speaker wire and some pretty thick wire for you power connection. First, you should take out the stereo and plug in your RCA cables (red to red and white to white)and then plug those into your amp as well. Then you need to find the wire marked Acc. on the wires in the back of your stereo. connect a pretty long wire to this wire. This will be plugged into your remote on your amp. The next thing you need to do is plug your thick cable into your positive side of your car battery and plug the other side into your power on your amp. The last thing you need to do for your amp is put a wire from the ground on your amp to a screw in your car that is unpainted and connected to the chassis. If everything else is hooked up correctly, you might need to play with the ground wire as this is usually the problem area. Then plug speakers into the appropriate places on the amp and box (Pos. to pos. and neg. to neg.) Make sure the amp turns off when your car does or you could drain your battery.
