T400X4AD

The Power T400X4ad 400 Watt 4-channel ultra-compact, amplifier is built on Rockford Fosgate’s proprietary Class-AD technology, featuring Constant Power to produce the same output at both 4-Ohm and 2-Ohm impedances. Flexible vehicle integration enabled through low-level and high-level inputs with auto turn-on. Top mounted controls allow easy access to built-in crossover and C.L.E.A.N. input/output clip detection circuits. The 3-stage thermal lock extrusion with dual fan forced induction keeps everything cool while real-time thermal/protection schemes safeguard the amplifier.

SMALL AMP WITH FAN. WORKS GREAT

The following review is for T400X4AD, which is a part of the bundle you are viewing.

wow, this is a tiny amp and it pushes 100 RMS per channel at 2 ohms. Rockford also makes a mono amp the same size. Perfect for small trunks. I have both amps, crossover, and a lc8i under where the spare should be. Happy I got it. Sonic Electronix has a great deal.
