Can this amplifier be used in a boat or outdoor environment?
Yes, the KMA300.4 is marine certified with a weather-resistant design, making it suitable for boats, ATVs, and other marine applications.
What type of power supply does the KMA300.4 require?
It requires a 10-16V DC power source, typically from a 12V battery system. A proper fuse (e.g., 40A) is recommended.
Can I bridge channels?
Yes, channels 1&2 and 3&4 can be bridged. For bridged operation, connect the speaker to the positive terminal of channel 1 and negative terminal of channel 2 (or 3&4). Minimum impedance is 4 ohms.
What is the input sensitivity range?
The input sensitivity is adjustable from 100mV to 4V, allowing compatibility with both low-level (RCA) and high-level (speaker) inputs.
Does this amplifier have built-in crossover?
Yes, it features variable high-pass and low-pass filters (50-250 Hz) for flexible system tuning.
What size fuse should I use?
Kicker recommends a 40A fuse on the main power wire near the battery for protection.
Can I use RCA inputs and speaker-level inputs simultaneously?
No, use only one input type at a time. The amplifier automatically detects when speaker-level inputs are used.
What are the dimensions of the KMA300.4?
The amplifier measures approximately 8.1 x 6.3 x 2.1 inches (L x W x H). Always verify fitment before mounting.
How do I connect the remote turn-on wire?
Connect the blue REM terminal to a 12V switched source (e.g., from the head unit's remote output). If unavailable, use a switch from the battery with a fuse.
