Why Choose This Product?
The T400x4ad gives you four discrete channels in one compact chassis for a front stage and rear fill. If your system calls for fewer channels, it also supports bridged operation, with the stated dynamic rating of 290W x 2 at 4 ohms.
Its constant-power design maintains similar stated output at 4-ohm and 2-ohm loads. That gives you more flexibility when selecting speakers for your system.
Installation & Compatibility Notes
Plan for the amplifier’s 1.6 × 4.3 × 8.3-inch dimensions and 8 AWG power and ground connections. The high-level inputs and RCA connections provide options for integrating the signal; remote-out supports auto turn-on compatibility.
