Home cinema and desktop audio builders

This amplifier suits anyone driving four passive speakers plus a powered subwoofer in a living-room, PC or vehicle installation. Tone controls let you adjust bass and treble to taste. Buyers needing more than four speaker channels, a built-in radio tuner or wireless streaming beyond Bluetooth 5.0 should consider other models.

40Wx4 RMS into 4-8 ohm speakers

The rated continuous output of 40 watts per channel across four channels is the figure that determines whether the S-299 can drive your chosen speakers to the desired volume. Peak power reaches 800W for dynamic passages, but the 40W RMS rating is the specification to match against speaker sensitivity and room size.

Questions about this item

What comes in the box and do I need to buy speakers or a subwoofer separately?

The amplifier arrives with its DC 12 V / 5 A power supply. You must supply four 4–8 Ω passive speakers rated around 40 W each and an active subwoofer with its own amplifier; neither speakers nor subwoofer are included.

Should I choose a different channel count or power rating for a small room?

This unit is a single 4.1-channel model rated at 40 W × 4 RMS with 800 W peak; there are no alternative channel configurations or wattage versions to select.

What does the 40 W × 4 RMS figure mean when I connect four speakers?

Each of the four channels can deliver 40 W continuously into a 4–8 Ω load, so all four speakers receive that power simultaneously; the separate subwoofer output feeds an active subwoofer without drawing from the 40 W per channel budget.
