Can I bridge this amplifier?
The FA2-1500.1 is a monoblock amplifier and is already designed for a single channel. Bridging is not applicable.
What impedance load is stable?
The amplifier is stable down to 1 ohm. It can handle 1 ohm loads without issues.
How do I adjust the gain?
Use a multimeter to set gain: for a desired output, calculate voltage using P= V^2/R. Start with gain at minimum and increase while playing a test tone until desired voltage is reached.
Does it have a subsonic filter?
Yes, the FA2-1500.1 features a subsonic filter adjustable from 10 Hz to 40 Hz with a 24 dB/octave slope.
What is the power output at 4 ohms?
At 4 ohms, the amplifier delivers 375W RMS.
Can I use it with a factory head unit?
Yes, the input sensitivity ranges from 200 mV to 6V, allowing compatibility with factory head units. You may need a line output converter if your head unit lacks RCA outputs.
What gauge power wire should I use?
For optimal performance, use 4 AWG or larger power and ground wire, especially for runs over 10 feet.
How do I troubleshoot no sound?
Check power connections, fuse, remote turn-on wire, input cables, and speaker connections. Verify that the amplifier is not in protect mode (red LED).
Is the remote level control included?
Yes, a wired remote level control is included and allows you to adjust bass volume from the driver's seat.
