If you are looking for serious power for serious sets of speakers, look no further than the Frx line of amplifiers. These are the can-do anything amps of DS18. Specifically designed to run everything, these full range amps are beasts that can power subwoofers, midrange speakers, and tweeters just with a few tweaks of the built-in crossover. These units have built in high flow fans to help with the thermal capacity, bass knobs to fine tune sound, and come in a very small package so you can save space for other important things. These amps are all 1 ohm stable so you can wire down and get all the desired speakers on one channel and can get the maximum power from the amp. These amps come in 1k, 2k, 2.5k, 3.5k, and 4x4k so the power options are vast!
