### ⭐⭐⭐⭐⭐ awesome extremely customizable
*by E***R on January 15, 2026*

a great amp that is highly customizable with the built in dsp

### ⭐⭐⭐ DSP? lol
*by A***D on October 24, 2025*

Amp is great but do not plan on using DSP, it is impossible to connect to and PE gives minimal support as they did not make this.

### ⭐⭐⭐⭐⭐ Amazing amp for it's price.
*by M***T on August 12, 2025*

Perfect for home audio or for building active studio monitors. Default factory settings is for 4 channel (perfect for car speakers), but if you bridge 2 of the channels together, that pair gets a low pass filter and becomes a subwoofer channel automatically which is perfect for a 2.1 setup. You can't bridge both sides (with factory settings) and get a 2 channel amp, they will both be left channels unless you reporgam the DSP. . The DSP onboard is good for setting up crossover, compressors, EQ's. You can use it to copy any one of those expensive studio monitors you see out there since it packs a great punch and you can tune it to sound however you like! If you're using it for an 8" monitor, you need a 24v supply (or you can go 36v but then it will be at maximum voltage all the time so the fan will kick on every few seconds). The Bluetooth cannot be turned off. You can disconnect the Bluetooth audio in the programming, but your phone will still connect without sound, but the Bluetooth board itself will always be on.
