Review: It is FOCAL quality! Nevertheless DSP features would be nice to add! - The amp was installed matched with the front and rear VW IS 180 and IC 165 in a TIGUAN, it works just flawless. Nevertheless the price I consider too high for what offers. There is other options in the market for $100 less but with DSP features, like Kicker. I purchased as it was at discount from $399 to $270, otherwise I would not be purchased. The high input is very sensitive so if using it keep gains like in a 1/4. I would suggest to use line level inputs as you can get a better control. The size is just perfect, it fits at any space so it can be hidden if you want.
