- Will it run two subwoofers?
- Yes, if they are wired together to a final load the amp can handle, such as two 4-ohm subs in parallel for 2 ohms. It is a single-channel amp and cannot be bridged.
- What impedance should I wire my sub to?
- 1 ohm gets the full 1500 W RMS, 2 ohms gives 750 W and 4 ohms gives 400 W. Match the sub's voice coils to one of those loads and check the sub's power rating.
- Does it have a subsonic filter?
- No subsonic filter is listed. The low-pass filter runs from 30 to 250 Hz, so very low frequencies below 30 Hz are not filtered out.
- Can I use it in a boat?
- It is not rated for marine use. Moisture and vibration in a boat are outside what this amp is built for.
- How much power does it need from the electrical system?
- At 1 ohm it draws high current, so use a properly fused power cable and a solid ground. A stock electrical system may struggle at full output.
- Where is the HiFonics A1500.1D cheapest?
- At Lowe's, for $289.99, as of our latest check.
