The Prime R250X4 is a 4-Channel amplifier perfect for any Car Audio Fanatic getting into mobile audio wanting a single amplifier to run a complete audio system. This amplifier features selectable Punch Bass to tune low frequencies, variable crossovers to either protect your high frequency speakers or feeding only bass to your subwoofers, and Pass-Thru jacks for daisy-chaining another amplifier.

An amplifier topology with the best of both worlds; a Class A preamp and Class B output stage. Class A topologies area great for sound quality but can require alot of current. Class B designs are great for power delivery. Amplifier designs utilizing a Class A/B topology reaps the benefit of great sound quality in the front-end (preamplifier stage) while delivering great power in the output stages (MOSFET drivers).
