Car Audio Capacitors Are a Waste of Money

After you have discharged the capacitor due to heavy power draw, the capacitor will need to recharge. How does it recharge? Well, the capacitor sits in between your battery and your amplifier. Once the capacitor is discharged, it will attempt to charge itself by drawing power from your battery. Then, when the amp needs power, the capacitor will supply current from the battery as well as any “extra” current it has saved up. Once its discharged, the vicious cycle continues.

Most common car audio capacitors are rated at 1 farad, while I’ve seen some reach as high as 5, 10, 20, and higher. No matter how high the rating, a capacitor will still hamper performance. This is because capacitors cannot supply the needed current for any extended duration of time. When your amplifier needs current, it will suck the capacitor dry in less than one second, leaving your capacitor to use your battery to charge up again. Once the capacitor is charged, that extra current can then be transferred onto the amp.

See where I’m going now? If a capacitor can only hold a charge for less than one second, while drawing substantial amounts of current from your battery in an attempt to charge back up while delaying power the amp, then what is the point? There is none. Capacitors are known in the car audio community as a marketing ploy to make people think they need something, when in reality, they really don’t. Take your money and invest it in a second battery. A capacitor these days runs between $50-$80. Add a few more dollars and you can get a second battery, which will supply your amplifier with much more power than a capacitor ever could, while not straining your electrical system.

Blaupunkt Car Stereo Experience – How to Choose Your Car Audio System

Blaupunkt car stereo has become one of the most reliable makers of mobile audio technology. You’re not just buying high quality car sound system with every Blaupunkt, you will also find reliable performance of stylish car audio components.

When I bought my Blaupunkt car stereo, I did not have any problems with its installation, as it was installed free of charge by a reliable Blaupunkt installer. I found out later on that plenty of Blaupunkt stores offer FREE installation of most car audio unit that you purchase.

Choosing a superior car sound system can be really challenging and can sometimes be painful, especially if you don’t know anything about car audio systems. Remember that speakers and components for a Blaupunkt car stereo are designed for different types of vehicles.

One of the most difficult issues that you’ll encounter in setting up your car audio system is when you’ll be working in tight spaces. If you plan to change your current car sound system with a Blaupunkt car stereo, you have the option to rebuild the entire system or just replace specific components. You can start piece by piece, say, starting with its speakers, which can you’d realize later on, is the most important part of your car audio system.

You need to do a little homework before you even decide to purchase a specific car stereo system. You might just have landed to this page because you are already beginning to do your research. In that case, I will help you identify important considerations in rebuilding your entire system, or in simply choosing specific components.

Car Stereo Repair

Have you ever experienced problems with getting your car speakers to work? Since I think many of us car owners have experienced this problem, I will provide this description of how to diagnose the problem of silent speakers and also give you some hints on how to fix it. Whether you are familiar with car stereo repair or not, this might help you. If it doesn’t, contact a dealer who can do an auto stereo repair or search for vehicle stereo repair help online. If your stereo speakers don’t work, then try

  • checking the speakers to see if they are disconnected
  • checking all fuses that are related to the auto speakers
  • tightening the butt connectors to the speakers
  • replacing all or some of the butt connectors

If your speakers are still not working, I recommend that you test the auto speakers that don’t work directly:

  • Disconnect each speaker that doesn’t work from the car’s wires and do the test below, doing one at a time.
  • Use a 9v battery and connect its leads to each auto speaker to be tested for a short moment.
    • Does the speaker have movement?
    • Do you hear the sound usually known as a ‘pop’ or thump?

    If your answers to the questions above are ‘yes’, your speaker will probably be able to make sound and it is likely to work.

  • Also note which way the speaker are moving, whether in or out of its frame during the test. Thus you can also determine your auto speakers polarity when connecting them up to the amplifier up in the front.
  • If the cone of your speaker moves out of the basket, the lead going to the positive of the battery is the positive lead of the speaker. If it goes in the opposite direction, the lead hooked to the negative of the battery is positive of your auto speaker.

This speaker direct test has two possible results: Either the speaker is not able to make sound or it is. If the first is the case, your speaker are dead and you must replace it. If the latter is the case, you should

  • run new speaker wires and rewire
  • perform the ‘popper’ tests to get the polarity correct as described above

Now, if this problem still persists you can at least rest assure that the reason is not your speaker. The reason is probably one of the following: Either it is caused by

  • problems in the deck itself or
  • the connections from the deck.

In this case I recommend that you contact a vehicle stereo repair shop or do a search online to get information about how to fix these problems.
