|
| Highlights | | Excelon Performance & Quality - eXcelon products incorporate the latest technologies and deliver the highest sonic performance. From advanced audio tuning capabilities, crossover and equalizer systems, high voltage preouts and two-year warranty, eXcelon represents the very best product available. | | | |  | Small Footprint Design - Reference-Fit amplifiers are Kenwood’s best sounding amps and have one of the smallest footprints in their class, making them the perfect solution for vehicle installation where space is at a premium. This compact size was made possible by the development of a high-density mount circuit board in conjunction with an enhanced air cooling and heat control system. Kenwood’s created a compact amplifier that enables installation in tight locations previously restricted to lower performance amps. This is ideal for users who do not wish to sacrifice space or prefer a stealth installation. | | | | | Dual Power Supply - This design results in two power supplies working together inside the amplifier to help stabilize the internal operating voltage under the most demanding conditions, ultimately reducing noise and improving performance compared to an overworked single power supply. | | | | | | Dual Sigma Drive -This advanced negative feedback circuit eliminates unwanted speaker movement, resulting in reduced distortion and accurate low frequency audio reproduction. | | | | | Air Cooling - By positioning the fan in close proximity to heat producing circuitry, heat is dissipated efficiently. This allows the amplifier to operate at comfortable temperature levels even under the most stressful conditions. | | | |  | Variable Low-Pass Filter - Filters high frequencies out of the music and improves efficiency and sound quality by allowing only the low frequencies to pass to the subwoofer. | | | |  | Infrasonic Filter - Eliminates frequencies too low to hear and too low for a subwoofer to reproduce. This improves subwoofer control, power handling and amplifier efficiency and prevents unnecessary oscillations causing distortion. | | | |  | Gold-Plated Line Input Terminals - This type of connector is non-corrosive and will maintain conductivity for long periods of time. Gold-plated connectors inherently have lower contact resistance resulting in wider frequency response, lower distortion with improved dynamic range and signal to noise ratio. | | | |  | Gold-Plated Battery/Ground Terminals - These HEX-type terminals can accommodate up to AWG 4 - AWG 6 battery and ground wire thickness for better voltage maintenance from the vehicle's battery. The HEX type design allows for maximum tightening and contact onto the wire. | | | |  | Gold-Plated Speaker Output Terminals - These HEX-type terminals can accommodate up to AWG 8 - AWG 12 speaker wire thickness for better signal delivery to speakers. The HEX type design allows for maximum tightening and contact onto the wire. |
