STINGER 4-channel amplifier SPX700X4

Stinger's SPX series amplifiers are very compact in size and all of them are IPX4 / IPX5 protected. The amplifiers have a wide range of installation options, such as various boats, tractors, ATVs, mopeds, campers and all other possible vehicles where the amplifier needs to be physically small and/or resistant to splashing water, for example.

The SPX700x4 is a four-channel Class D amplifier with physical dimensions of only 200 x 120 x 41mm.

The SPX350X2 is excellent for driving front and rear speakers, for example, or alternatively the amplifier can also be used as a three-channel amplifier, in which case it is suitable for driving front or rear speakers and a four-ohm subwoofer, for example. The amplifier has its own crossover filters for high or low pass for both channel pairs, or the filters can also be bypassed for both channel pairs if desired.
The crossover frequency is adjustable from 40 to 400 Hz and the crossover slope is 12 dB/octave.

The amplifier comes with a wired volume/level control, which also has a mute function. The control controls the Rear output, so it can also be used as a subwoofer level control, for example, if the Rear outputs are bridged for sub use.
