The SA4.500 is the first 4-channel amplifier in DD’s new SA (Small Architecture) series. This micro-sized amplifier delivers 4x 125 watts of continuous, clean power into a 2 ohm load.
The SA series amplifiers are the result of state-of-the-art, uncompromising design, offering incredible sound quality and unprecedented power in terms of size.
The SA series also uses the traditional DD AUDIO style chassis for maximum cooling.
The SA4.500 RCA connectors also support speaker level signals (adapters included in the package), so you can also connect this amplifier after the original car stereo. to speaker outputs
