- What does free-air mean for installation?
- The sub is designed to mount in an opening or panel without a sealed box behind it. That makes installs simpler, but output is looser than a sub in a proper enclosure.
- Is 2800 watts the real power handling?
- That is a peak rating. Continuous RMS handling is much lower, so match it to an amplifier's RMS output rather than its peak number.
- How do the LEDs get power?
- The built-in LEDs are wired separately from the audio signal. Plan a power and ground run for them when you install the sub.
- Can it be used in a car?
- It is built for marine use, but it can work in a car if mounted free-air. The marine finish and LEDs are the main differences from a car sub.
- Does it need a separate enclosure?
- No. It is made for free-air mounting, so it plays from a panel opening. A sealed box would give tighter bass but is not required.
