Frequently Asked Questions - PRX1500.1V2 Memphis Audio
What is the RMS power output of the Memphis Audio PRX1500.1V2?
The PRX1500.1V2 delivers 1500 Watts RMS at 1 Ohm, 1000 Watts RMS at 2 Ohms, and 600 Watts RMS at 4 Ohms.
What gauge power wire should I use for this amplifier?
For a 1500W RMS amplifier, use at least 4 AWG power and ground wire. Ensure the wire is OFC (oxygen-free copper) for best performance.
How do I adjust the gain on the PRX1500.1V2?
Set the gain using a digital multimeter or by ear. Start with the gain at minimum, play a test tone, and increase until you hear distortion. For precise setting, match the input voltage to your head unit's output.
Does this amplifier have a remote level control?
Yes, the PRX1500.1V2 includes a wired remote level control that allows you to adjust bass output from the driver's seat.
What is the recommended impedance for a single subwoofer?
For maximum power, use a subwoofer with a 1 Ohm final impedance. If using dual voice coil subs, wire them to achieve 1 Ohm. Always verify the sub's impedance capabilities.
What type of fuse should I use for the PRX1500.1V2?
Install an external 150A ANL or AGU fuse within 12 inches of the battery. The amplifier itself does not have an internal fuse.
How do I set the low-pass filter?
Adjust the low-pass filter (40-250 Hz) to match your subwoofer's specifications. A typical setting for a sub is around 80-100 Hz. Use a subsonic filter to prevent over-excursion below the box tuning frequency.
What are the dimensions of the PRX1500.1V2?
The amplifier dimensions are approximately 9.45 x 6.30 x 1.97 inches (240 x 160 x 50 mm).
Can I bridge this amplifier to power a mid-range speaker?
No, the PRX1500.1V2 is a monoblock amplifier designed specifically for subwoofers. It cannot be bridged; use a multi-channel amplifier for mid-range speakers.
What is the damping factor of this amplifier?
The damping factor is >200 @ 100 Hz at 4 Ohms, providing tight and controlled bass response.
