Our take on the MB Quart Reference RAA2400 by Crutchfield's Tim Sprinkle
The Reference Series RAA2400 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 2-channel powerhouse produces plenty of power to drive your subwoofers or speakers. 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- and high-pass filters to get the best sound out of your 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. 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.
LED indicators warn of distortion, handy when you're tuning up your system. And all Reference Series amplifiers are exactly the same size, so your MB Quart multi-amp setup will look perfect.
Bought this amp to push to JL Audio 12w1v2...and all I can say is wow! Lots of power left to get something beefier even. Running them at 2 ohm mono bridged on this amp. Very very strong, no lack of fine tuning with the built in crossovers. No complaints here! Awesome deal!

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.
Internal Crossover: The built-in crossover, adjustable from 50 to 5000 Hz, can be set for high-pass or low-pass operation, or it may be turned off for full-range output. The crossover has a slope of 12 dB/octave.
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.
Amplifier Wiring: The amplifier uses three 30A fuses, so its total fuse rating is 90A. 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 100A ANL fuse and ANL fuse holder.
