When you first buy a new stereo system for your car you will probably be in a rush to hook it up and start listening right away. However, it pays to take a few steps back and think before you begin tearing out your dash. Before you begin ask yourself the following three questions:
1. How much experience do you have:
If you have experience working with car wiring before then you have a good start. If you're a novice you might want to just let the pros handle it or at least read up. Also, how knowledgeable are you of your vehicle specifically? Although the general procedure is going to be generally the same, there are some different steps you may have to take depending on the make of your car, so take those into consideration.
2. How much room do you have
Not all cars can easily fit all systems. If you have an older car your not going to just be able to plot some huge DvD screen into it. Your going to need to cut out some trim and create more space. This obviously makes it more complex and more likely you'll need to hire someones help. If you have never done it before, it is probably not the best idea to start tearing away at your trim on your brand new car. Your going to be really disappointed if you mess something up, and believe me it's really easy to cause some serious damage.
3. What tools will you need
Depending on your car and situation you'll need a set of different tools. Maybe you'll need to take out some screws or bolts. You might need to drill through your firewall in order to power your new unit. If trim needs to be taken off, you will need something to take care of that. Go through the procedure of what you will be doing and think of all the tools you will need. This will not only save time, but will help ensure you do it right. This also applies to miscellaneous supplies. Your going to need something to keep those wires together and, as much as it pains me to say this, duct tape wont work.
And there you have, Three questions to ask BEFORE you begin. I hope they got you
