Are you capable to install car audio or video equipment???

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.
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.

I hope those questions will get you thinking, and either:
A. Reassured you that what your about to do is doable and you posses the skills to take care of it.
B. Helped you realize this is out of your abilities and it might be wiser to bite the bullet and hire a professional to install it. Remember, a car's electronics system is a very costly repair.
So good luck on your endeavor, whichever route you choose!
