Power Acoustik RZ4-1200D Amplifier vs Power Acoustik BAMF5-2500 Car Audio Class D 2500 Watt 5 Channel Amplifier

The BAMF5-2500 is the one to buy if you want a single amp to run front speakers, rear speakers and a subwoofer. Its fifth channel delivers 850W RMS to a sub, and the four main channels are adjustable. The RZ4-1200D is a small four-channel amp with fixed 80 Hz crossovers and 150W RMS per channel at 2 ohms. It suits a compact system with no sub channel. Owners of both report the rated power is optimistic, and the BAMF5 runs hot and needs room for its 17-inch chassis.

• Choose the Razor RZ4-1200D if you only need four channels, have a shallow mounting spot, and want a small Class D amp for speakers or a bridged pair of subs.
• Choose the BAMF5-2500 if you want one amp to power four speakers plus a subwoofer, with adjustable crossovers, bass boost and a remote bass knob.
