I bought this to run my Hertz HSK 165 components and my rear doors as well. Currently I have it connected via the High Level Inputs as opposed to RCAS and haven't had any complaints. The sound is clean, there is plenty of power available. Not much more I could ask for. I don't hear any strange sounds when it's running. It just runs and runs and runs. I don't know what else I could have expected in an amp. I will definitely use more of these.
