DS18’s GEN-X Series has a successor and is guaranteed to boost all systems to the top-of-the-line performance! The brand new G1000.4D is designed for the competitor and enthusiast on the journey to creating the system of their dreams!
The G1000.4D delivers pure power with unmatched reliability and efficiency so you can trust the heart of your system will never give out.
As a Class D amplifier, the G1000.4D uses Class D circuitry components significantly smaller than your average amplifier, making it the perfect size for any vehicle’s custom build: but, what it lacks in size it makes up for in power.
The G1000.4D comes with variable full crossover filter for crystal clear audio whenever you want it! Fully adjustable High Pass, Low Pass, and Full Filters give you control over your sound! Surface mount component technology allows for creative control over the placement and design of your build! High Level Input Compatibility for direct signaling to radio unit!
Protect your equipment effectively with Protection, Clipping, and Power Indicator LED’s that notify you when your amplifier has reached it’s limit!
The G1000.4D has a power output of 300W x 2 CH bridged at 4-ohms, 150W x 4 CH at 2-ohms, 90W x 4 CH at 4-ohms: perfect power settings to supercharge any custom build.
