MOTO 800 Amplifier

Description

New for 2025, ARC Audio is proud to introduce the all new MOTO800 compact high-power audio amplifier. The MOTO 800 is an ideal amplifier for vehicles and motorcycles alike with its compact design and wide range of flexibility.



This new amplifier delivers more power and features from the compact HD motorcycle-specific chassis of the legendary MOTO 600.4 and MOTO 720. While it carries the MOTO category name, many ARC Audio dealers find the compact 8.125 by 5.5-inch footprint ideal for under-seat in exotic cars and behind-seat installations in trucks.



The MOTO 800 delivers an impressive 800+ watts of power across its four output channels and up to 400 x 2 watts when bridged to a single four-ohm speaker. The Load Select switch adjacent to each speaker connection plug allows installers to optimize the power production capabilities for each installation. This flexibility is ideal for side-by-side and automotive applications that use front speakers that need full power at four ohms and a subwoofer that presents a bridged four-ohm load. Speaker terminal blocks integrated to the amplifier chassis deliver solid and reliable power delivery to the speakers in even the harshest of conditions.



Signal connections are made using the same quick-connect plugs that ARC Audio has used for speaker-level inputs on their amplifiers for decades. These plugs have proven their reliability and durability in thousands of installations and are compatible with the wiring in the MPAK kits and the PSM-Pro digital signal processor connections. These same input connectors are plug and play to the provided RCA signal input dongles that come with the amplifier. Input level range switches have been added to the front panel to make it easy for installers to switch between high- and low-level inputs. Each pair of channels features an adjustable sensitivity control that allows the amp to make full power with signals ranging from 200mV to 4V in low-level mode or 600mV to 14.0V in high-level mode.



Defeatable high-pass and low-pass crossovers that are adjustable from 50Hz to 500Hz allow each pair of channels to be configured for full-range operation, or use with a subwoofer and accompanying speakers. The high-pass crossover can also be used to optimize the performance of speakers like the MOTO CX6, MOTO CX69 or the MOTO602-HD high-efficiency coaxial speakers.



The amp can be configured to work with a single pair of inputs and knowing the enthusiasm of some of our clients, the amp has a 2-channel bridged mode that delivers 400 watts into a pair of four-ohm speakers.



All the sensitivity and crossover adjustments are made by removing the machined aluminum top-panel of the amplifier, so the system is easy to fine-tune once in place in a motorcycle fairing or under the dash of a side-by-side. This same removable top logo panel also prevents water from entering the switches on the top of the amplifiers.



The remote turn-on detection circuit remains the same with the same proven circuitry found in the MOTO720 including options for DC-Offset and Signal detection. These options ensure your installer can integrate the amp efficiently into any vehicle, if needed without the need for external processors.



Power and ground connections are made using a set of proprietary terminal blocks that will accept 8-AWG cables to ensure reliable performance. The remote turn-on connection moves to a similar dedicated terminal block beside the speaker terminals in this new design.



The MOTO 800 incorporates ARC Audio’s unique microprocessor design that monitors the operation and health of the amplifier across multiple zones. In the event of an issue, the onboard microprocessor will flash a sequence of lights displaying a unique code to identify faults in the installation or system component failure such as a damaged speaker or short-circuited speaker cable. An internal fan is controlled by the microprocessor to ensure the amplifier stays cool and sounds great in even the hottest of weather conditions and volume levels.



While the amp isn’t considered “waterproof”, the main circuit board of the MOTO 800 has two conformal coating layers to prevent damage in high-humidity installations and possible water from events like riding in the rain. The accent panel on the top of the amp has been enlarged to cover the top cover panel gaps, and all of the panel gaps have been tightened to reduce the chance of water drips from getting into the amp. Finally, the upgraded speaker connections blocks feature a sealed design that routes any moisture that enters from the top away from the circuit board. These key design features help make the MOTO 800 an ideal option for Motorcycle, Marine, Powersports and Automotive installations alike.



What separates the MOTO 800 from the ultra-compact amplifiers that many people use in motorcycle and powersports applications is the sound quality. The engineering masterminds at ARC Audio continue to sustain impressive S/N Ratio and THD specifications well over other competitors designs. Advances in power supply design and components have improved overall efficiency to an incredible 94% while reducing EMI and RFI noise production to ensure audio systems sound great.
