MB Quart RA1-280.4

MB Quart Reference series two channel car audio amplifier featuring innovative sound quality and power technology. The RA1-280.4 is a 280 watt car audio amplifier. Reference amplifiers feature DC Sensing to allow any amplifier to be easy integrated into an OEM system by simply adapting a RCA cable from the source unit. MB Quart output devices, FLUID-FETS are painstakingly selected for their ability to efficiently produce power and mimic the sound quality of the highest end home amplifiers. Heavy duty connections allow for secure electrical signal to pass into wiring and resist erosion which will add longevity to the amplifier.
