Power Acoustik VA1-10000D Vertigo Amp vs Power Acoustik RZ5-2500D Amplifier

These are two different jobs, not two versions of one. The VA1-10000D is a single-channel bass amp built to drive one or more subwoofers at 1 ohm, with a 3,500W RMS rating at 1 ohm, a subsonic filter and a dash-mounted remote gain knob. The RZ5-2500D is a five-channel amp that runs four door speakers plus a sub from one compact chassis, with high-pass and low-pass filters, bass boost and automatic high-level turn-on for factory radios. Buy the VA1-10000D if bass is the whole build; buy the RZ5-2500D if you want one amp to cover the whole system.

• Choose the Power Acoustik VA1-10000D if you are running one or more subwoofers and want a dedicated 1-ohm monoblock with a subsonic filter and a remote gain knob on the dash.
• Choose the Power Acoustik RZ5-2500D if you want to power four speakers and a subwoofer from a single small amp that works with a factory radio.
