This complete custom speaker installation kit has been designed specifically for the 1998-2013 Harley® StreetGlide, Ultra, or ElectraGlide fairing utilizing J&M's ROKKER XXR series 6.71" speakers. Spec'd at 2 ohms impedance and 400 watts maximum input (200w RMS - 91db sensitivity), these speakers provide the ultimate in raw audio power and include the new custom grills with built-in tweeter and midrange drivers. Speaker drivers feature lightweight waterproof woven-fiber cones with super-rigid metal basket and a high-density lite-weight Neodymium magnet structure, specially coated to maintain flux-strength integrity even at extreme operating temperatures. High efficiency VENTED voice-coils for improved cooling when operating at high volume levels for extended periods. Top-quality adapter rings and bracket hardware are included for secure and clean mounting into the 98-13 Harley fairing and are designed to utilize the old or new designs of the Harley inside-fairing metal-brackets. Mounting hole pattern and spade electrical connections are exactly the same as the factory specification, this is a total plug-and-play no-modification solution complete with easy to follow installation instructions. These are THE most powerful speakers you can buy for your Harley and they will perform extremely well when used with a medium to high-powered accessory amplifier. (NOT for direct connection to the 1998-2005 Harley RSI factory radio system).
