N**D
this is a mono amp (all is well when the description matches the product)
much of the description of this board is inaccurate.primarily, it's a mono (single channel) amp... meaning, it's not stereo and would be useable for only te left /or/ right channel, as a subwoofer amp or as a single-speaker (mono) set-up. past that it's a great board.the seller refunded the product cost when this was pointed out (thus the five stars), yet 3 months later, the description still reads: "100W output power channels(left/right channel and subwoofer channel), high efficiency and low-heat."make no mistake: one channel in // one channel out ... this is a mono amp.
