Install a CAR Head Unit
If you have an older car that doesn’t contain a CD player or want to update your stock CD player to include MP3 capabilities, personally installing a head unit in your car is quick, easy and fairly inexpensive if you have the proper know-how.
First off, you’ll need to buy a head unit, a wire harness and a dash kit (only if the head unit you bought isn’t a “direct fit,” meaning you’ll need the dash kit to help your head unit fit snuggly into the dash), all of which you can find at Wal-Mart, Best Buy,
Circuit City or Tweeter. Popular brands of head units are Clarion, Pioneer, Kenwood and Aiwa.
Tool-wise, you’ll need a butt connector, crimpers, a stripper, an adjustable wrench, a flattened Phillips screwdriver and possibly a socket set, depending on what kind of car you have. Most cars manufactured by General Motors or Mopar and most foreign will require the use of a socket set to pull the dash cover off if it is connected with bolts.
Once you’ve bought all the necessary materials, you’re ready to get started.
1. Start by disconnecting the battery in your car by taking the adjustable wrench and loosening the nut on the positive side and pulling the positive terminal (or wire) off.
2. Remove the dash cover. Though many dash covers are attached with clips or screws, some are attached with bolts. Depending on how your dash is attached, you’ll either need the use of a flattened Phillips screwdriver (screws) or a socket set (bolts).
3. Once the dash cover is removed, you can connect the wire harness to the head unit. Follow the directions that came with the wire harness. Simply, you’ll need to match the wire colors on the wire harness to the wires on the head unit.
4. Then, you’ll need to crimp both sets of wires together with a butt connector and a crimper. Before placing the wires in the butt connector, though, you’ll need to strip the wires first. Stripping the wires consists of taking the stripper about an eighth of an inch from the end of the wire and squeezing the stripper, pulling the coating off.
5. Put the head unit in the dash kit. Again, you can skip this step if you bought a “direct fit” head unit.
