YES, it its better than just any good! I don't know why people bash the 9.3" Power Acoustik PD-931NB. I have one, that I bought on Amazon, along with the 4 year warranty. I installed it in my BMW 740i and it works great. The touch screen is just like an iPad, and the DVD/MP3/CD player plays better than the BMW original unit.
Out of the box the speaker level outs, are 17W RMS X 4, so for just the head unit power, it sounds good.
There was no alternator noise with the speaker level outputs... but...
Here's my only problem, that I am asking for your help on, from anyone out there that has had this problem: I hooked up an Alpine amp via the RCA Preamp outs... and I have high pitched alternator noise. When I mute the head unit, or disconnect the RCAs, it stops. So its coming from the head unit, not the Amp. I have tried grounding the head unit to the same point as the Amp, and an Exterminator inline noise suppressor. PLEASE...can anybody help me get rid of the Alternator Whine ???
