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.

A Closer Look At Car Audio Crossovers

Car audio crossovers are a class of electronic filters designed for use in audio applications such as hi-fi. A dynamic loudspeaker driver that is commonly used is incapable of covering the entire audio spectrum all by itself.

Crossovers split the audio signal into separate frequency bands which can be handled by individual loudspeaker drivers optimized for those frequency bands. Let’s take a closer look at Kenwood’s KE-600 Crossover, KPX-F801 Crossover and Kenwood KPX-L101 Crossover.

Kenwood KE-600 Crossover

Kenwood KE-600, one of the most advanced signal processors, is a 6-Way electronic crossover with built-in parametric equalizer and a DC to DC power supply for high voltage outputs and low noise.

It has input selection, phase switching, variable level controls and the following outputs: subwoofer, low-pass, low-cut, high-cut and high-pass. It is a great component for multi-amp installations and is available for around $370.

Features

● DC to DC converter.

● High-frequency output.

● Input selector.

● Different phase switches.

● Subwoofer output from 30Hz to 800Hz (low-pass).

● 6-way multi-amp configuration.

● Variable level controls.

Kenwood KPX-F801 Crossover

Kenwood KPX-F801 Crossover is a 3-way passive crossover network. It is available for around $75.

Features

● Guard circuit that protects against excessive tweeter inputs.

● Special capacitors and inductors for audio purpose.

● Phase inverter switch for midrange and tweeter.

Kenwood KPX-L101 Crossover

Kenwood KPX-L101 Crossover is a low-pass passive crossover network. It is available for $50.

Features

● Special capacitor and inductor for audio purpose.

● 80Hz crossover.

Remember, an audio crossover splits the incoming audio signal into separate bands that do not overlap at all, and which, when added together, gives the signal unchanged in both frequency and phase response.
