I only can complain about the inputs. I wish the inputs weren't pre assembled on the clip so I could use my own wiring
I bought 2 of these during the sale event and installed one in my daily F-150 Super Crew, and just finished the second one today in my daughters Mustang. There are rumors of heating issues but haven't experienced any yet. These little amp sound great. I'm very impressed with their small size and great sound quality as well as the level. I definitely recommend this amp especially when a small size is needed.
Great definitely does the job love the size very compact and just looks perfect in my car
Its a decent amp but the first thing I noticed is that the gain pots are backward. They go from 0.2 to 8v and you would think that 8v is Max but that is not the case (at lest on mine?). Make sure you tune these amps with a sine wave tone generator, a multimeter, oscope, or an SMD DD1 to make sure you aren't clipping your signal.
For the price though its a decent amp and it fits basically anywhere. Good value for the money.
Skar, please consider changing the printed gain indicators to Min-Max to avoid confusion or at least ensure the pots attenuate in the proper direction. This was very confusing initially.
