Kicker and Kuryakyn: Competently Combining Quality Components

What would happen if we combine the innovation and style of Kuryakyn with the audio expertise and sound quality of Kicker? We thought it’d be good to explore the notion, so we recently joined camps and came up with some of the best-looking and best-sounding motorcycle audio systems on the market today.

Best of all, you don’t have to be an electrical engineer to install a complete audio system upgrade on your late model Harley-Davidson Touring bike.

With such a great selection of Kicker Audio products from which to choose, we have some exciting opportunities to upgrade your current Harley-Davidson audio system. We’re also proud to include the Kicker Amp (Kuryakyn Part No. 871) as the heart of our audio upgrade. This kicker amp enables you to continue to possess the functions of your current audio controls, only with increased clarity and volume. And even more important, this amp is optimized for use in late-model Harley-Davidsons, which means you know everything’s going to fit and work just right.

As with any new product, there are questions and concerns, which prompted us to create the following Q&A to address some common concerns and shed some light on some of the possible applications of the Kicker products.

What is the power output of the Kicker Amp (Kuryakyn Part No.  871)?

The Kicker Amp (Kuryakyn Part No. 871) has a maximum output of 46 watts per channel RMS at 2 ohms resistance and a total of four channels; Right Front, Left Front, Right Rear and Left Rear.

What is the advantage of using the Kicker Amp (Kuryakyn Part No.  871)?

The Kicker Amp allows for use of all stock controls and audio functions. It also includes a wiring harness for plug and play installation for up to four pairs of Kicker KPS5250 Speakers (Kuryakyn Part Nos. 874 & 875).

What is the resistance of the stock speakers?

Stock speakers on the 2006 and later models are 2 ohms.

What are ohms?

Ohms are a measurement of resistance to current flow. The lower the ohms or resistance per channel, the more power required to drive or power the channel.

Why is speaker selection and installation so critical?

When choosing speakers for use with the Kicker Amp (Kuryakyn Part No. 871), the maximum current flow output should be matched to 2 ohms total resistance per channel. That means that if the total circuit has 2 ohms resistance, you will achieve maximum performance or output from the amplifier. If you reduce the resistance of the channel to less than 2 ohms resistance, you can damage the amp by requiring more current flow than it can handle. This has the potential of shutting it down and not functioning at all. If the total resistance is greater than 2 ohms, there will be less output or current flow, resulting in lower performance.

  • Optimal output with 2 ohms resistance per channel
  • Great output with 4 ohms resistance per channel
  • Good output with 6 ohms resistance per channel
  • Poor output with 8 ohms resistance per channel
  • Harmful output with less than 2 ohms resistance per channel

What is meant by Series versus Parallel speaker installation?

When speakers are installed in Series, their respective resistance or ohms are added together. This can be used with the Kicker Amp to ensure that the maximum output of 2 ohms per channel is not exceeded. When the speakers are installed in Parallel, the total circuit or channel resistance is decreased and current flow is increased. Care must be taken not to decrease total channel resistance to less than 2 ohms.  The formula looks like this:

Speaker 1 resistance X Speaker 2 resistance / Speaker 1 resistance + Speaker 2 = Total resistance

So when using a 4 ohm speaker and a 2 ohm speaker on the same channel installed in Parallel, the total resistance formula would look like this:

2 X 4 / 2 + 4 = 1.3 total ohms —— This is too low and will not work

For optimal output, you will want to use two 4 ohm speakers installed in Parallel for total channel resistance of two ohms:

4 X 4 / 4 + 4 = 2 total ohms

What does a Series circuit wiring diagram look like?

What does a Parallel circuit wiring diagram look like?

Why is the Kicker Amp required when using the Saddlebag or Fairing Lower speakers?

The Kicker Amp (Kuryakyn Part No. 871) kit contains all the wiring necessary for installing up to eight speakers in either Series or Parallel. We can’t be responsible for other amplifier specs or outputs. That’s because we can’t be certain of the sound quality when installed with other amplifiers. As a result, there’s the potential for possible damage from the unit being overpowered,  possible damage to the stock radio or poor sound quality if installed without an amplifier.
