Do not buy unless you are a professional electrician. This product doesn't come with a wiring diagram of any kind and does not tell you how to wire it.

I have an Echo Show in my bathroom that I like to use when I get ready for work in the bathroom. It’s not very loud when I’m in the shower and could use more just in general. Enter this speaker system. I was able to install this Bluetooth system with speakers into my bathroom relatively easily and pair my Echo Show with the wall receiver and now I can hear my morning briefings and other Alexa controlled content easily and understandably. The wall receiver fits into a single gang electrical box and connections are made in the back for speakers. The wall receiver has a place for power and auxiliary connections in the back too but I currently just have my power connected to the front and speakers in the back. I will eventually figure out how to run my 12-volt DC power into the wall so I can have a clean finish on the system but for now I just plugged power into the jack available on the front. The aux audio can also be connected to the front if you have a 3.5mm connection needing to play. For me, I just wanted the Bluetooth for my Echo and connect it wirelessly. My set didn’t come with a DC power adaptor but I have several around the house and just found one that fit the plug on the front and was up and going. The speakers came with a cutout template for cutting the holes and all the wire you need for average spacing to get back to the control box. You’ll need a small flat screwdriver to terminate the wires on the back and they are labelled so you know which terminal to connect the positive and negative wires too. The speakers also came with a gasket to go between the grills and the ceiling. I bought a hole saw with the size I needed to make installation a little easier and accurate but you could use a sheet rock saw just as well. If you’ve never installed anything into a ceiling before, make sure to check where your studs are. You sure don’t want to cut through those when you cut the holes out. Once you know where the speakers will go, cut your holes and you can easily fish the wires from one hole to the next as the holes are large enough to get your arm up into the attic the pull the wire. If your speakers are going far apart and can’t reach, a straightened metal coat hanger works wonders as a fish tape push rod. Once I got everything wired up and plugged in, I simply set the selector to BT (Bluetooth) and turned on the power. The controller immediately went into pairing mode and I told my Alexa to connect to Bluetooth. My Echo synced up and connected and I was able to play music now over my speaker system in the bathroom. You can adjust the volume up and down from a rotary knob on the controller but I actually set mine to 75% and tell Alexa to change volume levels if I want to adjust. Since I leave my system on now, I don’t have to physically change anything on the controller and can let Alexa do the work for me. Once I figure out a way to run my 12-volt DC down inside the wall I will get rid of the plug on the front and it will have a nice finished professional look to the system.

This is a pretty cool bluetooth speaker setup. You install the 4 speakers in wall or in ceiling and connect them to the amp module that is also wall mounted. I question the 600 watt rating but the speakers do get loud enough for my taste. It is pretty cool to be able to set the input to Bluetooth and port music for many of your Bluetooth devices (phone, tablet, pc, echo devices etc).

These work well as surround speakers. They have the potential to have some bass, but that also requires them to be in enclosed boxes. Used as surround speakers, you're not really looking for any sort of bass but more voice and special effect sounds. They mount in the drywall pretty easily, but the hardest part for anyone is going to be running the speaker wire. In un insulated walls, it's easy, but if it's an insulated wall....good luck. The speakers seem well made and have the crossovers built right onto the speakers. You don't have to use the included amplifier system because they are just speakers and will work with any sort of receiver that you have. Anyway, they look decent once mounted and serve a purpose for me, so I find them to be a good value for what you get.

Installed these speakers in the game room. Really disappointed in the sound quality. Simply not enough power pushing the speakers. Can't recommend these speakers. Many other better options to consider on Amazon in this price range.

Installed all four speakers and the In-Wall Receiver. The system does NOT come with a power supply, so after purchasing one and plugging that in, the unit powers on, but does not put out any sound. The bluetooth connects but the LED does not light up and no sound comes out. I tried the AUX and MIC sources and still no sound is generated. Very disappointed in this product.UPDATE:So after leaving the above review along with a one star rating, the Seller RETX reached out via Amazon messages wanting to see if they could rectify the situation. First of all the product does come with a power supply. Also, I discovered that my in-wall amplifier was defective (not working). After exchanging messages back and forth, In about ten (10) days, RETX sent me a replacement amplifier unit and the power supply, all free of charge.I was able to install the amplifier and power supply and the system works wonderfully. Before I was contacted about the replacement parts, I ordered another in-wall amplifier to get the system up and running. I had installed the Herdio Bluetooth 4 Channel Wall Amplifier. After switching out the in-wall amplifiers, the PNWCZ sounded slightly louder than the Herdio. I see other reviews saying that the speakers are under powered with this amplifier, which may be the case, but the system in an eight foot ceiling sounded good and is louder than my Bose Soundlink Flex. For the price point of this product I am extremely happy with the sound quality and loudness of these speakers.
