About this product
Borrowing from Powerbass's former ACS series, these new amplifiers offer upgraded features, terminals and a dual layer PCB all packed in the most compact chassis allowable. To accomplish this they selected SMD parts and engineered a brand new high density heat sink engineered for maximum efficiency and cooling. The result, an all new line-up of two, four, five and mono channel models that offer amazing performance and fantastic value. Ultra efficient, the PB Series amplifiers produce plenty of low distortion high fidelity audio in a footprint small enough to fit nicely in nearly any vehicle. The PB Series Amplifiers provide the perfect mix of performance and style in a sleek new compact chassis.

The G1000.4D is a 4-channel car amplifier from the DS18 G series, built as a Class D design. It delivers 2 x 300 watts RMS at 4 ohms, 4 x 150 watts RMS at 2 ohms and 4 x 90 watts RMS at 4 ohms. The channels are bridgeable, so you can combine them to drive a subwoofer or a pair of higher-power speakers from the same amplifier. Total harmonic distortion is rated at 0.01% with a signal-to-noise ratio of greater than 90dB. A selectable LPF/FLAT/HPF crossover covers 50Hz-2KHz, so you can send each channel only the frequencies it should reproduce. Bass boost is adjustable from N/A centered between N/A. Match the amplifier to the RMS rating of your speakers or subwoofers and set the gain to that rating for clean, reliable output.
