"Cheap Sound"0.5 starson by E_Net_Rider
Pros: Adequate hookups and features, but not really a plus with the output being so poor.
Cons: Extremely poor bass with most songs. Treble not terribly good either. Adjust limited to +/- 6 db and maxed it has less than my small sub on computer. My two previous amps drove these speakers without any trouble whatsoever (my mains have 16" woofers)
Summary: ;My factory car audio is much better, THX certified. I am trying to work this out with dealer and Yamaha. Only hope for this unit is it being defective. I gave Yamaha a try because of claims the user interface is better than Pio-n-eer, which was very poor on my last unit, but superb audio.
