The Power Acoustik OD41800 is a four-channel Class A/B car amplifier rated at 900W RMS and 1800W max. It runs full-range speakers or bridged channels for subwoofers, with adjustable crossovers, gain controls and a MOSFET power supply. Built-in protection covers overheating, overload and electrical faults. It suits budget-minded drivers powering a full front-and-rear speaker setup or a small sub stage. Against pricier Class D four-channels it runs hotter and draws more current, but Class A/B sound is the trade-off many buyers accept at this level.

The Power Acoustik OD41800 is a 4-channel Class A/B car amplifier. It is rated at 900 watts RMS and 1800 watts maximum output. It is full range, so it reproduces highs, mids and lows, and it can power full-range speakers and select subwoofer setups.
The Class A/B design balances efficiency and sound quality. Use it to power front and rear speakers, or bridge channels for additional output. A MOSFET power supply provides stable power delivery.
Adjustable crossovers and gain settings let you tune the system. Built-in protection circuits guard against overheating, overload and electrical faults.
