This is a truly amazing Harley-specific speaker. Hertz hit it out of the park with this design. The large oversized 1.4-inch tweeter is the loudest non-horn tweeter we have ever tested and it is louder and better sounding than many stand-alone horns. The woofer of this speaker is a pro audio design that has been optimized for use in Harley applications. Designed to perform in the fairing, tour packs, and lower fairings these woofers deliver clarity and loudness for even the largest scale systems.

Features:

1. Nature-proof high stiffness pressed-paper cone featuring innovative water/ humidity resistant and anti-UV treatments.

2. Durable Extreme SPL performance in a compact size & light-weight thanks to the N38 H Neodymium grade magnet.

3. Unparalleled power handling delivered by the double layer copper voice coil, wound on polyamide former.

4. Hi-SPL 1.4” Neodymium magnet PEI dome tweeter with resettable solid-state tweeter protection circuit.

5. Double faston terminals allow daisy-chaining of multiple units and provide compatibility with most common motorcycle connections.

We are true believers in the all-new SV 165 NEO speakers because we were consulted by Hertz (Elettromedia of Italy) during the design phase and we got our hands on prototypes to use in our own bike a long time ago. It didn't take long for us to report back to Hertz that these speakers are spectacular and perfect for Harley applications.

They asked what we wanted to see in a speaker and we told them.

• Waterproof
• Treated for UV Exposure
• Improved Bass Response
• Premium Neo Magnet
• Higher Resonant Design
• Smooth Frequency Response 
• Efficient, Loud, Extreme Power Handling 

Features:

• Compact dimensions and light weight preserving excellent performance thanks to the use of Neodymium N38 H for the motor units
• Cones waterproofing and anti-UV treatment to allow safe outdoor use without discoloration over time
• Motor units treated with cataphoresis and insulated lead-wires to avoid oxidation
• Terminals and mounting holes compatible for installation on Harley-Davidson motorbikes

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.

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.

Features:

1. Small and weatherproof – perfect for motorcycles

• Compact size featuring all connections on one side to be installed anywhere

• Anti-corrosion-treated PCB to ensure years of listening pleasure in open nature

• Three different application setups: Car, Motorcycle, Free placement (boat, van, pick-up)

• Party & Ride presets, to optimize the sound performance in all conditions

2. Configurable with a PC, a Mac, an Android device, or an iOS device

• IOS/Android control APPs (Bluetooth 5.0)

• DRC control over app from iOS/Android devices

3. Powerful DSP with the excellent sound quality you expect from Hertz
