Kit includes custom made connection harnesses and is 100% plug-n-play into the Ultra’s electrical system, providing 4-channels of amplification at 230w RMS power per-channel x4 (920w RMS total) into a 2-ohm speaker load. New high-efficiency Class-D IC circuitry, (no cooling fans needed) properly shielded against FM/AM radio interference. PCB is conformal coated for complete protection against water damage in the motorcycle or powersports riding environment. This ROKKER amplifier uses advanced digital switching power supply technology to dramatically reduce the 12v current demands on the motorcycle electrical system, compared to other brand amplifiers in this power range. Amplifier is tuned for connection to the Harley GTS, 6.5GT, or 4.3 Std radio with Stock Harley Flash and is also fully compatible with the Sound Stream HDHU.14si, Precision Power HDHU.14si, & Fosgate PMX-HD14. Amplifier mounts to the Lazer-cut stainless steel 2-piece bracket system, to provide solid and secure mounting inside the fairing. Custom made plug-n-play JMC red-band wiring harnesses are included with this complete amplifier kit, top quality heavy gauge power/ground wires are used for the fused battery connection, along with all necessary mounting hardware & complete installation/operation instructions. Amplifier is dialed-in for this specific speaker configuration, to provide maximum highway performance. Amplifier itself measures 8 ¼ x 5 ¾ x 1 ¾”. ROKKER XXR 6.71” speakers are spec'd at 2 ohms impedance and 300 watts max input (- 91db sensitivity), these speakers provide maximum on-highway performance. Speaker drivers feature lightweight waterproof woven-fiber cones with super-rigid metal basket and a high-density lite-weight Neodymium magnet structure with integral high-output grill-mounted PEI tweeters. Mounting hole pattern and spade electrical connections are exactly the same as the factory specification.
