CT-400.1D / Single BIO-8 D4

Caught a flash sale at the same time I was building a small system in my wife's car. Wanted something small, discreet, and a low end fill in for her daily driver. Sub worked perfect with my small space requirements in a custom made sealed downfiring rear console box. The amp fit perfectly under the passenger seat and disappears into the interior of the car.

CT-400.1D Review: This amp is a beast in a very small package! The amp I received seems underrated, but more testing is required. Set the gain with an oscilloscope and initial testing doesn't seem to clip until it's close to 350W RMS on a 2 ohm load! Amp fit well in my tight space requirements, and delivers clean power to a single Bio-8 D4 in a sealed box!
