This Is The Part You Need! Adding An Amplifier To Your 2014 Or Newer Harley Davidson Touring Bike Has Never Been Easier.

True Plug & Play! This is the very best way to integrate an aftermarket amplifier with the factory radio of any '14 or newer Harley bagger. This harness gives you all of the connections and features you could want and it works with all variations of Harley stereo systems from basic to CVO Ultra models, both factory-amplified and non-amplified.

This Part Replaces All of the Following Harnesses. Which makes it the best deal, and the cleanest and easiest way to go:

• 2014-Up Harley Plug & Play Signal Adapter 14FPNP
• 2014-Up Harley Plug & Play Rear Signal Adapter
• Stealth Accessory Harness Power Tap
• Rear Harley Speaker Wire Harness for Bags or Tour Pack
• Stealth Power Tap Harness for Battery & Ground
• Ultra Rear Radio Signal & Speaker T Harness
• Harley Speaker Pod Plug Adapters for Fairing Speakers

Fitment: 2014 and up Road Glide, Street Glide, Electra Glide, Ultra, CVO, and all amplified and non amplified variations. Amplifier bypass plugs required for all factory amplified systems.?Amplifier bypass plugs are available. Balanced speaker level on RCA, requires an amplifier or DSP that is designed to accept speaker level in on RCA connection (most all quality amplifiers and DSPs do accept speaker level, but check your equipment to make sure). CVO and bikes that only have fairing speakers will require a radio flash to enable the rear RCA output. You can flash your own bike with a separate single bike flash tool.

Does Not Work With Sound Digital Or Dayton Amplifiers (there may be others we're not aware of though)

• True Plug & Play! No cutting any factory wires.
• Both front and rear (4 Channel) RCA out from factory radio (balanced speaker level on RCA, requires an amplifier or DSP that is designed to accept speaker level input on RCA connection).
• Front and rear speaker connections for factory locations.
• Built-in load resistors keep factory radio happy and eliminate distortion.
• Accessory, battery, and ground outputs for powering DSP without the need for any additional parts or plugs.
• Wire ferrules and crimp connectors built into the harness. No extra connectors needed.
• 100% developed and designed by American Hard Bag in the USA.

This power amplifier kit comes complete with all the cabling, speaker wires, terminals, disconnects, and waterproof fuse holder needed to perform a quality installation for a typical amplifier, except for RCA interconnects.

What We Like About This Kit:
It has a waterproof eight gauge fuse holder that uses mini ANL-style fuses for superior current transfer and reliability. Furthermore, the fuse holder is compact and very friendly to mount. All of the wire runs are blacked-out with a nice-looking braided loom and heat-shrunk at each end.

Are you looking to add 6x9's to your stock lids? Don't want to spend the big bucks and buy color matched CVO lids from the dealer? Yet you don't want to chinch out and buy crummy aftermarket lids. The Hertz HD14H saddle bag lid cut-in kit makes it possible for you to add their 6x9 speakers to your stock, non-speaker lids you currently have without sacrificing quality, safety and without emptying your wallet.

Will only work on stock, non-CVO lids, without electric lid lock motor, on 2014+ lids.

DON’T SETTLE FOR 5X7S WHEN YOU CAN HAVE 6X9S IN YOUR FACTORY HARLEY SPEAKER LIDS!

This kit requires modification of your factory speaker lids. The integrated plastic basket on the underside of the speaker lid must be cut off and ground down to create a flat mounting surface for the adapter to mount on. This is done quickly and easily with an oscillating cutting tool, or a Roloc disc on a die grinder.

This kit includes (8) eight aluminum threaded nutserts. A nutsert tool with an 8-32 insert is required to complete the installation. If you do not have a nutsert tool, one can be found locally, check with your nearest Hardware store or tool company. 

Update!: This kit will now work with CVO electronic lid lock mechanisms, but you must select the optional lid lock adapter above before adding it to the cart.

The ultra-compact S8 DSP is the perfect solution for integrating any OEM source into your audio upgrade project for cars, motorcycles, and boats! S8 DSP is a distilled essence of technology at the service of the highest audio quality in a corrosion-free case cast in metal and composite materials.

S8 DSP processes the audio signal with 96 kHz / 24-bit resolution and has obtained the Hi-Res certification from the JAS (Japan Audio Society), an acknowledgment that certifies the extreme level of audio performance achieved.

The powerful 32-bit DSP manages 6 high/low-level analog input channels, one digital coaxial input, and 8 output channels, offering maximum freedom of configuration to the specialist. The SPDIF coaxial input is ideal for digital connection with a Hi-Res player, a solution that allows for maximum listening quality. For each of the eight output channels we have a level control, the 15-pole parametric equalizer, time delays, and crossover filter available. The 7-band parametric equalizer of the input signal allows obtaining a flat response from OEM sources, which often have an exaggerated emphasis on the low frequency.
