About: Infinity INFM10001AAM 1000W RMS Monoblock Marine Amplifier 

Marine 10001A mono subwoofer amplifier delivers a blistering 1,000-Watts RMS using Class D amplifier topology to ensure cool running and minimal current draw. Speaker-level inputs allow this amplifier to integrate into almost any system, even one using your marine's factory radio — and Infinity includes RCA-to-speaker wire adapters so you'll make the right connections. You can use the low-pass filter and variable bass boost to maximize the performance of your subwoofer and enclosure, while a phase switch ensures that the bass will blend well with your full-range speakers.

Features:

• Compact size
• Infinity amplifiers have been engineered with a compact footprint to fit in more boat even if available space is limited.
• Input Level Control
• When low-level inputs are used, this control adjusts the input sensitivity between 200mVrms and 4Vrms. When high-level inputs are used, this control adjusts the input sensitivity between 1Vrms and 22Vrms.
• Phase Switch
• This switch changes the input phase to inverted or non-inverted. This is especially helpful with the subwoofer channel.
• RBC wired remote
• The RBC wired remote is an easy installation and can be mounted for convenient volume adjustment from driver's seat.
• Strappable for up to 2,000 watts of power at 4 ohms
• Enable to strap two marine 10001A together to double your power, the Primary amp will be in absolute control of Secondary in terms of the crossover points, the gain and remote level control
• Turn-on mode
• This switch changes DC to REM to adapt with low-level signals or high-level signals, this is especially helpful as part of remote turn-on lead of your installation more choice. A selectable "Turn-on mode" can protect battery to avoid current drain, when you don't expect turn on your amplifier.
• INPUT Mode
• Multiple switching: Switch to 2 Ch: To control RCA inputs from #1 and #2 channels:
• - The audio signals from input #1 will be transformed to output #1, #3, #5 and #7;
• - The audio signals from input #2 will be transformed to channels #2, #4, #6 and #8. Switch to 4 Ch: To control RCA inputs from #1, #2, #5 and #6 channels.
• - The audio signals from Inputs #1 will be transformed to output #1 and #3;
• - The audio signal from #2 will be transformed to Channels #2 and #4;
• - The audio signals from Inputs #5 will be transformed to output #5 and #7;
• - The audio signals from Inputs #6 will be transformed to output #6 and #8;
• Switch to 8 Ch: Each of all inputs are transforming its corresponding output #channel.
