There are many brands and options out there. Kenwood, Pioneer, JL audio, and Sony are top of the line in this category. Each of these brands offers an entire line of stereos that are suited to fit different needs and budgets. Match the colors on the harnesses or follow the included diagram. This makes it much easier to install and later remove the head-unit should you decide to take it to another car, and a wiring harness adapter usually only costs around $20 or less. You may also need to purchase an antenna adaptor for your new head unit and vehicle. You will need a service manual such as Haynes, but any manual that provides details for your make and model should work. Every stereo is different, and sometimes it is required that you remove parts of the dash/console to remove the stereo. This is where the manual will be most helpful. It can also be helpful to have a comprehensive guide on aftermarket stereo installation. This will cut power to the car and allow you to safely work on the electrical components (like stereo wiring). This will usually consist of taking off some portion of the dash and or faceplate (consult your service manual) and then taking out the mounting screws that hold in your head unit. Once you’ve done this, the unit will slide right out. It will be plugged into the back of your head unit. You will have access to it when you pull the head unit out.  Some people choose to cut these wires away (especially if they didn’t purchase a wiring adaptor) but this can void the warranty. The wires will be clearly marked, as the adaptor is designed to make your car and head unit fit together. Crimp the wires as instructed in the wiring harness adapter's instructions. After crimping (or soldering as some choose to do), twist on appropriate sized wire nuts and make sure to keep your wires as neat as possible. This part is even easier than connecting the adaptor to the head unit. It literally is designed to plug right into your factory wiring harness. Do that now. If you needed an antenna adaptor, you can plug it into the back of the head unit and plug the antenna lead into the adaptor. Otherwise, your antenna should plug directly into the back of the head unit. The size of your original and aftermarket head units may be different. They typically come in one of three sizes - Single DIN, DIN and a half, Double DIN. If your aftermarket head unit is a different size than the original, you may need an adaptor, or DIN cage, to mount it. If they are the same size, the aftermarket stereo should bolt into the original mounting brackets for the head unit. This is where your service manual will come in handy again. Now you need to put back together any pieces of the dash that were removed to get the stereo out. This will restore power to your car, and by extension, your new head unit. Now you should be able to turn on your stereo and enjoy a crisp, clean sound.

Q: Washing your jacket too soon could do harm to its fibers. Even after six months have passed, you should only machine wash your jean jacket rarely. Wash jackets on a cold cycle, unless otherwise indicated on its care instructions. Jean jackets made from special fabric blends may have unique care instructions. Always follow the jacket’s label care instructions for the best results. Hang your jean jacket on a wooden hanger in the bathroom when you’re taking a shower. Keep vents off and windows closed to build up the steam. The steam will smooth wrinkles and could even eliminate faint stains and odors.  To preserve your jacket the longest, try a shower steam treatment before anything else. Water may condense on metal or plastic hangers. If too much water accumulates, it can stain your jacket or create streaks where it has dripped. When hanging your jacket, do so in a way that keeps it from the surfaces of the room. Your jacket may absorb dirtiness or excessive moisture from walls, doors, and so on. Fill a bucket, bathtub, or similar container with enough cold water to completely submerge the jacket. Add a half cup (118 ml) of vinegar to the water. Stir the solution to distribute the vinegar, then soak your jacket in it for roughly half an hour.  Treating your jacket with vinegar will help maintain its color. This is especially useful for dark colored jackets, which sometimes transfer dye to other clothing, furniture, and so on. Although vinegar has a potent smell, when your jacket dries this smell will disappear. Leftover solution can be disposed of down a drain. Machine drying your jacket will dry it more quickly, but the heat from the dryer will cause its fibers to break down, weaken, and fray. Hang your jean jacket from a clothesline, a hanger, or on the back of a chair to let it air dry. When hanging or draping your jacket to dry, pull on the fabric to straighten wrinkles. This will reduce the amount of wrinkling in the dried jacket.
A: Wait at least six months before washing new jackets. Refresh your jacket with shower steam. Soak your jacket in a distilled white vinegar solution. Air dry your jacket.

Article: Just anyone. Even if it's "What homework do we have in algebra?" It's an excuse to talk to people. Make them laugh, but don't try to be funny. Talk about things you can relate to, be really friendly and always smile, be tight with people; just don't be too open with your secrets, personal things are called personal for a reason and you could really damage your reputation if you let people gossip behind your back. Just know who your real friends are. Ask the cool girl you sit next to in science if she wants to go bowling this weekend and frequently throw sleepovers. If you invite people to do things, they will have to invite you to do things. Sure, this worked in Mean Girls, so why wouldn't it work in real life? This is because things like this only happen in movies, not real life. Think: would YOU like to be known as the girl that is rude to everybody? Neither would we.
Question: What is a summary of what this article is about?
Talk to people. Invite people to do stuff with you. Don't be mean.

Article: If your doctor agrees that you have a kneecap dislocation, he/she will likely perform a procedure called a “reduction,” which will slide your kneecap back into place.  The doctor will likely give you pain medication before manipulating your knee to minimize the discomfort. Generally he/she will follow this procedure with an x-ray to make sure everything is in the correct place. Again, it’s important to not try this at home as it is difficult to figure out which injuries need surgery or specialized treatments, and further damage can occur if this is not done correctly. If you have a rare type of dislocation or additional injuries, your doctor may need to consult an orthopedic surgeon (a specialist surgeon who treats bony injuries) to determine whether surgical intervention is necessary.
Question: What is a summary of what this article is about?
Prepare yourself for a reduction. Be aware that some dislocations may require surgery.
