CT Sounds CT-700.1D Monoblock Amp vs CT Sounds CT-80.4D 4-Channel Amplifier

These are different tools, not rivals. The CT-700.1D is a 1-ohm stable monoblock built to drive subwoofers, rated 700W RMS at 1 ohm, 380W at 2 ohm and 200W at 4 ohm, with a subsonic filter, bass boost and a remote bass knob. The CT-80.4D is a full-range 4-channel, rated 80W x 4 at 4 ohm, 125W x 4 at 2 ohm and 250W x 2 bridged, for door speakers or a small sub. Owners of the monoblock praise its durability and cool running; the 4-channel carries the higher rating count and a slightly lower score.

• Choose the CT-700.1D if you are powering one or more subwoofers and want a compact, strappable monoblock with a bass knob.
• Choose the CT-80.4D if you need to power front and rear speakers, or bridge it to two channels for a modest sub.
