A month back, I pulled the trigger on the Power Acoustik PD-931NB. Now, it's been about a month and I'm ready to review it (and tear it out to install my stock unit back in)

Power Acoustik PD-931NB (PD931NB) In-Dash 9.3" Inteq Car Receiver

Image


History: My research has concluded that the company that made this head unit has also branded the same model under the name of SoundStream and Farenheit, same model# 931NB or 931NBT.
The NBT has a TV turner.

The Install: Crutchfield and Sonic Electronix both claimed that this headunit fits in a 2012 Tundra. It does fit, but not with the Scosche Tundra dash kit. I had to trim off the opening for the head unit to fit. This is where I spent most of the install time. I think if I used the Metra tundra kit it would have been easier because Metra has a bigger opening. The head unit also sticks out since it has an over sized 9.3" screen. Thus, I also had to trim the wider trim bezel that came with the unit. Again, more time spent adjusting the little things. Wiring was easy, and straight forward. This unit also has RCA speaker outputs which I used since I have an amp for the speakers and an amp for the subwoofer.

The Screen: 9.3" inch screen - size is nice, big. But wait! There is a BAD glare on this screen! Thus, I can barely see anything during the day. At night, it is fine. I have stock tint in the rear windows, none on the front. I think if I had tint on the front windows the glare would not be so bad.

The Software: The unit responses to each tap of the screen is OK (and I say OK very lightly). It could be better and faster. Versus Pioneer or Alpine units, which I've played around with at BestBuy and Fry's, the screen response sucks. There is some sort of film that makes it almost feel like you're pushing a button on every tap. There no customization with the unit (at all). The settings are all very basic, elementary. In other words, if you have no idea how to adjust a head unit, and have never used a decent head unit before in your life, this is the head unit for you. Everything is basic, almost like a child's training toy on how to use head unit. (Seriously)

The Features: SD card reader only recognizes 25% of my videos. All the formats are exactly as stated in the manual, yet still no explanation why the 75% of the videos cannot be played. iPhone4 compatible, you have to use the IC3 cable to connect the phone to the unit - However, since the connection is on the side of the screen, it is an eye sore to me to see wires hanging off the side of the screen to my phone. Versus the stock USB port is close and low to the center console where I place my phone. Playing videos (that do work) are good, loads quick for an hour long show. However, the names of the videos (for example TV shows from iTunes) don't always display. Sometimes, it displays the name of the episode, other times the name of the TV show. Radio is basic, does not tell you the name or title of the song playing or radio station, etc. The reception is weak, versus the stock head unit where I could get many stations clearly without any static. The bluetooth connects auto or manual, but when using bluetooth for audio, there is no title of songs or artist on the screen. Just a play, stop, forward, and back button. Making/Receiving calls is OK (not great) - you can actually see your last dialed numbers, phone book, but it is not easy to use, and you can't use the remote for that, you have to touch the screen.

The Remote: You can only use it for certain functions and features. For example, if I wanted to go to the home screen, I'd have to use the touch screen to navigate to it... Making the remote about 75% useless for me.

Other notes (more complaints): I bought the 931NB model, without the TV turner. However, when I navigate thru the available sources, i.e. DVD, Raido, iPhone, etc, I have the option to go to TV Turner... I thought I bought the model WITHOUT it... I'm not sure why they would have it available on this model.

I haven't used the navigation because you need the NaviBox additional component. Which retails about $200-$300... which means the price of the head unit... I passed on the navi for now.

The unit also FAILS to turn on the amps about 20% of the time since I've had it. There have been a number of times when I have people in the truck, and the radio turns on but no sound. So I turn off the unit, turn it back on - NO sound. I remove the screen, put it back in - NO sound. It isn't until I arrive at my destination, turn off the car and back on - the amps finally turns on. And YES I did correctly install the ACC, +12v, amp turn on wires, etc. Trust me, I checked!

Conclusion: I could go on and on with how HORRIBLE this piece of junk is... I'm not sure if this will help anyone or if I just needed to vent on how stupid and dump on the little to no engineering went into this head unit. I cannot believe any of the good reviews on SONIC or anywhere. They are all full of it. Or they all have no idea of what a quality piece of car audio equipment really is.

Overall, I'd recommend to STAY FAR FAR AWAY from this brand/company for head units. I know some of us use their amps, speakers - which I'm sure are OK since there isn't much user interface with amps/speakers.

My advice to them - (1) Hire some REAL car audio enthusiast to design the user interface (2) Test your products, and test them thoroughly (3) Think logically, not like a baby. This thing is just JUNK.

Yep...

I once ordered a power acoustic amp kit, it came, it was like 8 ga with tons of sheathing...

power acoustic anything is shit. Sorry, plain and simple, no other way to put it...

Then again, at @259, it is a decent deal to someone that hasn't had functional steering wheel controls, or an unnecessary fully functional remote...

For $259 anything is a joke unless it is a basic head unit without video.

I have a Clarion in my gfs jeep, I bought it in about 02ish, it smokes the head unit you installed, remote works right, had immaculate sound, however it is a single din unit and 12 years old...(by year code) however, back in the day I paid about 229-259 wholesale. It is still a rocking ass head unit, however I can not get an adapter to make steering wheel function with it other that Ir units....

Otherwise I would install it in my truck and have my gf use her oem hu..

You get what you pay for man, sorry.

Here are some pics:

I've also posted these in another tread.

Day time, with a sunshade. You can easily see the reflection of the interior roof compartments.

This is the top view, you can see how much the unit sticks out. This is with the "thinner" trim bezel that came with the head unit.

Here is what I had to trim off: It is the red part I trimmed off so that it would align with the round curved

I don't trust anything Power Acoustik sells. I've seen pictures of that radio in other cars before and couldn't think anything except how awful it looks. Truly does look like an iPad just slapped in there, haha. I hope you'll be able to get your money back for it.

Thanks for the thorough explanation of the problems... now I can pass this on if anybody else I know asks my opinion on Power Acoustik again!

Just a quick follow up again: So it appears that this unit has a heat dissipation issue. On hot days, 90degrees +, the head unit won't turn on the amps, meaning it won't trigger the amp turn on wire. It won't be until about 10 min of driving with the A/C on, or windows down (when the interior of truck has cooled), I'll restart the head unit and finally the amp turns on...

A quick follow up since my last post.

I've tinted the windows on the truck now, 35% front windows and 5% rear windows. Making the inside of the truck much cooler now, the radio actually works about 10% more of the time now.

On really hot days, like the past two weeks about 90 degrees+, the head unit still won't turn on the amps. After about a 10 min drive with the air condition on MAX, I'll restart the head unit (turn off then back on) and it is OK - amps turn on and everything is normal.

Again, it is more than likely a heat dissipation issue... :runinafire:

On another note, I've gotten myself a nice Android phone. Bluetooth still works great. I can play music and take calls without changing any settings (versus the stock HU where you have to reconnect your iPhone to play music OR take calls - But not both). However, I have to select songs thru my Android phone, little to no control over song selection thru the unit or head unit's remote.

I'm still sticking to my initial comment: Piece of JUNK!

I'm going to part this guy out on ebay soon. And either pick an Alpine unit or build a Car-puter with a 10" touch screen.
