About the MB Quart Reference RAA1000
The Reference Series RAA1000 amplifier from MB Quart delivers the high-end performance and reliability you need for a serious audio system. Housed in a sleek, low-profile black chassis, this mono powerhouse can produce up to 1,000 watts to multiple subwoofers. Its convenient top-mounted controls make tweaking the output a snap, while removable end caps hide all of the wiring for a professional-looking installation.
Use the built-in low-pass filter to get the best sound out of your subwoofer/box combo, then adjust the subsonic filter to eliminate the inaudible, ultra-low bass that can hamper performance. You also get a set of preamp inputs and outputs for tapping into your other audio components — flexibility that means this amp can be incorporated into just about any system.
If you're using an outboard preamp or crossover, you can bypass the amp's built-in gain and crossover controls for a cleaner sound. The included remote level controller lets you adjust low-frequency impact right from the front seat. And all Reference Series amplifiers are exactly the same size, so your MB Quart multi-amp setup will look perfect.

Features
Inputs and Outputs Notes
Wiring Recommendations
Trans-Nova (Transconductance Nodal Voltage Amplifier): This circuit simplifies the signal path of the amplifier, allowing the signal to travel through the amplifier at a low voltage. The result is greater reliability, cleaner performance and exceptional musicality with the speed, durability and power of MOSFETs.
MEHSA (Maximum Efficiency Heatsink Application): MEHSA is a process that yields up to 5 times better heat transfer than traditional FET mounting techniques using the exact same components. A multiplayer insulated metal substrate operating with minimal thermal resistance spreads heat both downward and outward to quickly dissipate heat from each device across the heat sink.
Low-pass Crossover: The built-in low-pass crossover is adjustable from 50 to 250 Hz. The crossover has a slope of 12 dB/octave.
Bass EQ: The Bass EQ allows you to adjust the Q from 2 to 4. Q changes the effective bandwidth of the boost control at the selected frequency. Higher Q values reduce the effective bandwidth, lower Q values, increase the effective bandwidth with an adjustable frequency control variable from 25Hz to 100Hz.
External Controller: The external controller lets you adjust the gain level (0 to -20 dB) and the bass boost level of the amplifier from anywhere in the vehicle. The external controller has the following dimensions: W=1.979", H=1.131", D=2.995" (including the knobs and attached cable).
Subsonic Filter: The subsonic filter allows the amplifier to block ultra-low frequencies that your subs can't reproduce, improving the efficiency of your speaker system. The filter is adjustable from 15 to 50 Hz and has a slope of 12 dB per octave.
Phase Switch: The phase is a variable control used to adjust the phase of the output signal relative to the phase of the input signal. The phase is adjustable from 0 to 180?.
Line Outputs: The amp includes a pair of RCA line outputs for sending an unfiltered signal to another amplifier or component without splitting the signal.
Front End Defeat: The Front End Defeat is used to reroute the input signal around the signal processing circuitry within the amplifier. While in the On position, all gain and crossover functions are bypassed. This feature was designed for use with external processors to provide the purest possible signal path through the amplifier.
Set-screw Terminals: The power, ground, and remote turn-on terminals are on the power plug connector, which plugs into the power plug receptacle on the amp. The speaker terminals are on the speaker plug connectors, which plug into the speaker plug receptacles. The power and ground set-screw terminals will accept up to 2-gauge wire. The remote turn-on and speaker set-screw terminals will accept up to 12-gauge wire.
Note: The power and ground terminals each have an installed sleeve that allows you to use 8-gauge and smaller wire. The sleeves must be removed to use wire larger than 8-gauge.
Remote: This RJ45 jack allows you to connect the supplied external controller.
Amplifier Wiring: The amplifier uses three 40A fuses, so its total fuse rating is 120A. Since pre-packaged 4-gauge amplifier wiring kits normally have 60A or 80A fuses, you will need to replace the fuse and fuse holder in the kit with a 150A ANL fuse and ANL fuse holder.

I purchased this amp along with the 10" 4 ohmn Premium Sub from MB Quarts and the sound is Flawless. Please notice it's deminsions and make sure it will fit. It is quite large. The alluminum case is very rich. All the adjustments allow you to make it your Bass!
