A device that increases or boosts the level (volume) of an input signal by increasing its amplitude.

A single module of a power amplifier designed to carry one signal only, keeping it separated from signals in other channels (left, right, front, rear, etc.).

A fixed or adjustable electronic circuit that splits or filters an audio signals frequency bands for driving different speakers (high range, full range, low range). There are two kinds of crossover implementations, Active and Passive: Active Crossover – This filters selected frequencies BEFORE the audio signal is amplified, between the source unit and amplifier. Our built-in crossovers are an example of this type of crossover. Passive Crossover – This filters selected frequencies AFTER the audio signal has been amplified, between the amplifier and speaker. Some speakers are sold with passive crossover networks included, typically a small plastic enclosure (like our CX Series), or capacitors and/or coils mounted directly to the speaker (like our SX Series).

A unit of measurement used to indicate Sound Pressure Levels (SPL) as numbers from 0dB (quiet sounds such as a whisper) to 130dB and beyond (the level at which sound is perceived as pain).

A safety device that breaks an electrical connection when current exceeding the rating of the fuse occurs (in Amps).

The amount of sensitivity an amplifiers input circuit has to the input signal, increasing or decreasing the output in dB (volume).

A crossover circuit designed to allow only high frequencies to pass through.

A crossover circuit designed to allow only low frequencies to pass through.

A measure of an amplifiers output based on the amplitude rise above ground (0 volts), regardless of signal distortion created in the process. Also used as a measure of a speaker's maximum handling capability of a power source for a short duration (typically a few seconds) without sustaining damage.

A method used to calculate the nominal power level sustainable by an amplifier or speaker. The most realistic measurement of continuous power ratings with minimal distortion, used for realistic comparisons between devices rather than measuring 'peak power’.

A unit of measurement for power output or consumption ( P ), the product of voltage ( V ) and current ( I ) ( Watts = V x I ).

Nothing. Zero. Zilch. All of our products come with everything you need to install them on a factory bike. If your install is custom and goes beyond factory limitations, let us know if we can help.

Here's a list of tools needed to work in/around your fairing:
T-40 Torx Wrench
T-27 Torx Wrench
T-25 Torx Wrench
1/2" Hand Wrench
7/16" Hand Wrench
3/16" Hex Wrench
P2 Phillips Screw Driver
Wire Crimmpers
Wire Strippers
Wire Cutters

Unfortunately at this time we can't offer installation or customization as a service, as we're really set up to design, test, build, and ship our products. Maybe someday though...

No, they don't. We put a lot of engineering into our amplifier designs to make them reproduce your favorite tunes without causing problems or interference with your equipment. Keep in mind that when installing a hidden antenna inside the fairing, it's a good practice to keep it 8"-12" away from any power supply source (radio, amplifier, etc.).

These are the names given to the 2 touring fairing designs by none other than Harley-Davidson themselves. It's a simple matter of what they look like:

Sharknose Fairing
Looks like the nose of a shark, the fairing used on Road Glides.

Batwing Fairing
Looks like a bat with wings, the fairing used on Electra Glides and Street Glides.

We use this terminology around here because it's usually the only physical difference to deal with when installing an audio system in your fairing, regardless of your specific bike model.

Deciding between the DCS and PSC amplifier systems is more than just a question of money. It's really about what kind of system you're looking for long term. Here's the breakdown:

DCS vs. PSC
120W vs. 150W
Fixed gain vs. adjustable gain
Fixed crossover vs. adjustable crossover
Simple harness connection vs. separate PWR/GND/audio wiring

Measuring a stock system the way we rate our amplifiers, there's a huge difference in power. Even with the DCS amp and SX speakers you'll gain a whole lot of power and volume, plenty to hear at highway speeds on a stock or mild bike. For FLHX's or modified bikes (short windshields, loud pipes, etc.), we recommend the PSC systems for the best possible results.

In a nutshell, if you're just looking for a quick, simple installation that does the job of putting the music in your ears on the open road and does the job well, the DCS setup is perfect for most stock bikes. If you're looking for the maximum power possible with the ability to tune and configure your system, try different speaker options, add more amplifiers and speakers someday, or your bike is good and loud, then the PSC system is the way to go. Both systems are considered “plug and play” as neither one requires modifying any of your stock wiring.

Either way though, you'll get your money's worth where it counts; in your ears on the open road.
