Crunch GTX1600.4D

The Crunch GTX1600.4D from the GRAVITY GTX series is a powerful 4-channel Class D amplifier in an exceptionally compact design. Despite a width of just 135 mm, the amplifier delivers up to 4 x 200 watts RMS into 2 ohms, making it ideal for powerfully driving front and rear speakers or high-performance component systems.

Thanks to its bridgeable design, the GTX1600.4D can also be used flexibly with various combinations of speakers and subwoofers. In bridge mode, up to 2 x 400 watts RMS at 4 ohms is available. The efficient Class D technology enables high output power despite its compact dimensions.

Crunch offers extensive filtering options for adapting to different car audio systems. The front channels feature a highly adjustable high-pass filter, while the rear channels offer high-pass, low-pass, and band-pass modes. Additionally, the bass range can be boosted using a bass boost function.

In addition to RCA inputs, the GTX1600.4D features high-level inputs with EPS® (Error Protection System). This allows the power amplifier to be integrated into many vehicles equipped with factory-installed radios or OEM sound systems. An automatic power-on function via the high-level signal further simplifies such OEM installations.
