CT Sounds CT-1500.1D Monoblock Amp vs Kicker CXA400.1T

The CT-1500.1D is the pick for anyone chasing big subwoofer output: it is 1-ohm stable and rated at 1500W RMS, roughly four times the Kicker's 400W RMS. The Kicker CXA400.1T is the better fit for a modest single sub or a factory-system upgrade, with a smaller, lighter chassis, preamp outputs for daisy-chaining, and Kicker's long-standing reliability reputation. Owners of the CT Sounds amp praise its power in a small footprint and cool running; the Kicker is the conservative, lower-strain choice.

• Choose the CT-1500.1D if you run one or more subwoofers that can take serious power and want 1-ohm-stable output, subsonic filtering and bass boost in a compact chassis.
• Choose the Kicker CXA400.1T if you have a single sub in the 300-400W range, want preamp outputs to feed another amp, and prefer a light, proven amp that is easy to mount.
