Step 1: Describe Your Needs to Car Stereo Installers or Car Electronics Shops
Explain what type of car audio, car video, GPS navigation system or security alarm system you want. Be consistent and specific in the way that you present the information so each of Los Angeles County auto electronics specialists will have an opportunity to meet the same needs.
Step 2: Answer the Electronics Dealers' Questions & Ask Some of Your Own
You'll learn a lot by the questions each car audio, video, navigation system, and car alarm retailer asks. Take note of what questions each auto electronics representative has about your inquiry. Does he cater to your needs or just want to get you in and out? Does he exhibit a firm knowledge of the equipment he's selling? Is he listening to what you are saying, or does he push a specific product over and again?
Illustrate that you are an informed consumer by asking questions. Take notes on the answers and how you personally feel about the car electronics representatives. Remember, the stereo installers' attitude at this stage can impact your satisfaction with the sale.
• How long have the car electronics dealers been in the car stereo, car GPS navigation or car alarms business?
• How many car audio, video, navigation, security systems or alarm system sales and installations have the car electronics dealers completed in Los Angeles County?
• Do the car alarm companies or car audio video installers specialize in a specific type of electronics system?
• Are the car alarm system or portable GPS navigation installers accustomed to working with my type of car or truck?
• Do the car sound systems come with car speakers, subwoofers, amplifiers, radios, CD players and MP3 players?
• Do the auto electronics dealers specialize in the car audio, car video, car alarms or GPS navigation system in which you're interested? If so, ask for examples of similar systems that the electronics dealers have sold or installed.
• How do car audio or car electronics stores determine pricing on vehicle electronics systems, GPS navigation systems or car alarms?
• Will the car electronics dealers provide a written estimate for the car alarms, vehicle navigation systems or car amplifiers?
• What type of warranty will the car electronics stores provide? Will the warranty cover all car audio systems including car amplifiers, car speakers?
• Do the car navigation systems dealers or car audio installers do the installation work on site?
It is important here to understand your own needs to avoid being sold sub par or unnecessary equipment.
Step 3: Make a Preliminary Decision on a Car Stereo or GPS Navigation Systems Dealer
After you've spoken with different automotive stereo, video and security vendors serving Los Angeles, Beverly Hills, Santa Monica, Malibu, Long Beach and Redondo Beach CA, it's time to narrow the field. Review your notes and assess which aftermarket car electronics in Los Angeles County will be your best choice.
Which car audio, portable GPS navigation, car security systems and car alarms or car audio electronics products do you like best? Which car audio and video and car alarms vendor do you believe had the best quality installations in your price range? Which did you personally feel the most comfortable dealing with? This is very important and should have become more evident by this process.
Step 4: Do Some Final Research on Your Car Electronics Choices
After you've selected your first choice automotive stereo, automotive video and automotive security system store, it's time to do some final research. What credentials and sales history does the shop have? Don't forget to check the certifications of the technician performing work on your ride, as well.
Step 5: The Final Decision on a Car Stereo, GPS Navigation System or Car Alarm Dealer
Now it's time to select and purchase the car alarm, GPS navigation system, car stereo system or other car electronics for your automotive needs. Call and ask any final questions and then ask for the representative to provide a written and signed pricing, quality and warranty agreement.
Tips About Car Stereos & Auto Electronics in Los Angeles, Beverly Hills, Santa Monica, Malibu, Long Beach and Redondo Beach CA
Know Exactly What Auto Electronics You Need.
The purchasing process will be much more difficult if you don't know what you want or need.
• Do you need a new audio, video, navigation system or just a couple of car speakers?
• What brand of car stereos do you prefer?
• What components do you want in your car stereo system or car sound system (car speakers, car subwoofers, car amplifiers, car radios, car CD players, car MP3 players)?
• How many car video monitors do you want, and where do you want the car video monitors placed?
• Do you want a car DVD player or car video system?
• What kind of GPS auto navigation system do you want?
• Do you want a portable navigation system?
• Do you want other car electronic features such as car remote systems, keyless entry systems, car remote start systems or remote starters? What about car audio accessories?
• Know what kind of automotive security systems you want—car alarms, car alarm systems, auto security systems, car security alarms, talking car alarms or car-disabling car security systems.
Knowing specifically which auto electronics products you want will give you a more accurate picture for timing and pricing.
Research the Vehicle Electronics Products You are Considering.
There are many quality automobile electronics products out there, and chances are, your local Los Angeles County car audio and video specialist offers a majority of them. Use the power of the Internet and trade magazines to sort overpriced and low-quality products from those that will serve you best. This independent research, combined with the salesperson's knowledge, will guide you in your decisions on the best car alarms, car stereos and car audio systems.
Take Your Time Choosing Your Automotive Audio, Video and Security System Specialist.
You're not required to buy from the first automotive stereo, video and security vendor that answers the phone. If you take a little time up front to properly outline your needs and find the right mobile electronics dealer before starting the audio/video/security systems purchase process, you're less likely to be disappointed.
Slow Down and Get Your Car Electronics Plan in Writing.
Make sure that Los Angeles County automotive electronics shop of your choice provides you with a written description of the product(s), pricing, installation, and warranty information.
Do Your Homework Before Making an Agreement on Automotive Audio, Video or Security Systems.
For larger auto electronics purchases in Los Angeles County, be sure to check licensing, sales history, warranties, customer satisfaction, and any other relevant credentials before you sign. It may help to visit a company's website to view past projects they've completed.
Write a Description of the Auto Electronics Job.
You'll do better in assessing who the best car stereo installers and car alarm dealers in Los Angeles County are if you personally write down which products you want and what you expect your finished project to look like. You might also include pictures from other finished projects for a well-rounded example. Since each technician will see the same description, you can be sure that you are comparing responses on an "apples to apples" basis. Then you can better judge which car audio, video, and car security dealer gives you the best responses to your consistent description. This is a good stage to test the candor and honesty of each shop, and decide whether they will look after your best interests.
Maintain Great Communication During the Car Electronics Systems Work.
From misunderstanding what you want, to unexpected delays in product shipping or installation, frustration can occur. Meeting the Los Angeles County auto electronics dealer halfway in communication will significantly increase your chance of a successful sale. Ask questions when you have the slightest doubt about the process.
Know Your Rights When it Comes to Working with Car Stereos, Car Audio or Car Alarms Dealers.
Consumers have some special rights, depending on where they live. Since you're dealing with retailers of automotive audio, mobile video, and automotive security systems in Los Angeles County, check out the Consumer Affairs website for the state of California.
Make Sure Your Audio, Stereo, and Security Shop Representative Asks the Right Questions.
If your specialist seems not to care about what you've said or glosses over key issues, take your business elsewhere. Your time and money should not be taken lightly. Make sure you are dealing with the most senior representative available, and that your business is valued. Remember that you're not the only one that should be asking questions. A good aftermarket mobile electronics dealer should go over the areas important to you, asking questions along the way and actively listening.
