Thunder4300x Amplifier

expand

--------------------------------------------------------------------------------
The front and rear crossovers are 18dB/octave, continuously variable between 50Hz and 200Hz high pass or low pass, giving you several options in setting up your system.

The new symmetrical power supply allows for better thermal distribution.

The "sum output" jacks on the four-channel amplifiers provide a line level summed output of the right front/right rear and left front/left rear input signals. This output is typically used to drive an external subwoofer amplifier.
