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.

Power Capacitors

Power Capacitors

What are they?

Power capacitors work by acting as a reserve power bank; they store the charge rather than being the source of power such as the battery. When you are listening to your music, and playing a heavy sub-bass note, the power will draw from the capacitor rather than from the battery so to ensure that the rest of the car will not be starved of power i.e. the headlights dimming. It will act as a buffer so that that the power being delivered to the amplifiers will not drop below the recommended voltages and be steady therefore reducing the risk of damage to the components.

So what power capacitor to choose?

After doing a bit of research, the general rule seems to be 1 farad per 1000 watts of power that your system is running at. So using that, a 1.5 farad power capacitor should be ideally suited to a 1500 watt system. There is a large selection of power capacitors available out there, for example, this power capacitor is a 2 farad power capacitor designed for smaller systems, this is not to say however that it will have a reduction in performance, however for those systems that require more power, a power capacitor with a higher farad will be able to deliver for longer and will usually be of a higher build quality. For a high quality power capacitor, I would recommend high quality car audio brands such as Rockford Fosgate. For example there is a selection of Rockford Fosgate series digital capacitors that are available in either 2 farad power capacitor or 10 farad power capacitor options that are well suited for highly demanding systems and as an added bonus, some might even say they look the business!

How to install the capacitor

Ideally the capacitor needs to be installed as close to the amplifiers as possible. The capacitor requires a 12 volt positive from the battery and a separate ground, to the amplifier; so that the 12 volt positive is 'inline' with the terminal from the battery and the amplifier. The amplifier 12 volt positive is then taken from the capacitor while the amplifier is usually grounded separately as it is important to use as short a ground cable as possible to reduce any potential ground interference.

 

When you need to consider other alternatives

Power capacitors will not always be of help when you are listening to music, if the lights for example dim down, and stay dim, this indicates there is a deficiency of power and there are other methods of solving the problem, it could potentially be that the battery is not able to generate a charge sufficient enough to meet the demands, so installing a higher cranking battery is usually the common solution however it is possible that upgrading "The Big Three" may also solve the issue(see below for more details). It is also important to check that the current alternator can produce a charge that will be sufficient with a larger battery.

'The Big Three'

The big three is a popular upgrade. It consists of upgrading three wires in the car to ones that are much thicker. As a result of using much thicker wire, more current is allowed to flow through; hence the overall effect seen will be that the voltage running through the car will be higher. The three wires that are upgraded are the wire from the alternator to the battery, the engine ground to the chassis and the battery ground to the chassis. It is common, but not always, that people will choose 0 gauge power wire when going about the big three upgrade. This is vital again to ensure that the voltage delivered to the amplifiers does not drop so low that the risk of damage is possible.

Conclusion

So in conclusion, there is no hard or fast answer to if a capacitor is necessary or not. However capacitors may have benefits if used appropriately. There are large selections of capacitors; some come with digital volt meters, distribution blocks etc, while others are purely chosen for aesthetic pleasure, I myself went for a 4 farad power capacitor with a built in digital volt meter with an LCD display so that it was something I was able to display and looks pretty damn cool.

Would you stick with this or start over with something else? Is it true that the 13w7's are the best subs money can buy?

head unit would be better if it were a pioneer, alpine or eclipse. amps without a doubt zapco. mids zapco , rainbow , mb quart. as far as subs go with treo, image dynamics, or boston acoustic. jl subs are over rated and way over priced. if you research jl has never won anything except for a few innovation awards. never use oval speakers they have no real sound quality no matter how much you pay. and without a doubt upgrade your electrical system. that means high output alternator, deep cycle battery and big 3.
