Fosi Subwoofer Amplifier 300 Watt Mini Mono Stereo Audio Amp:
Ordered on July 5th - Received in YUL on July 22nd
Bought this amp to convert my Active 300 Watt PSW125 Polkaudio into a Passive Sub.
Connecting the amp to both the receiver and driver is straight forward.
Once powered on, crossover, and volume adjustments are to taste!
Sounds great at all settings - Works as advertised!
Very happy of my purchase.

I am amazed by reviews of this product that say it underperformed. I purchased this amp to replace the blown amp on a 150 watt Kef sub and it drives it just fine.

Super solid construction and always runs cool.
