Small in size, big on sound!

The CT Sounds 400.1D amp was literally 1/2 the size of the one it replaced (a vintage Kenwood from the mid nineties) despite the compact size I was surprised & impressed at the quality & performance. I would recommend to anyone that needs a great amp @ a great price point.
Email was also promptly answered,so these guys are also focused on customer support! Highly recommended! Thanks CT Sounds.

Dual strapped CT 400.1D's

Bought a second 400.1 D to run pair strapped to two Tropo 10's at a 2ohm load. Well exceeded my expectations. I come from the old school 90's car audio world where it was about a dollar per watt. The pair of these amps for a just over $200 and a real 800 watts RMS amazes me! I wouldn't believe it if I didn't hear it.
