Waterproof Off-Road Speakers 800W RGB Lights Marine Grade 4" (2 Pair)

The photos say bluetooth compatible, wireless audio streaming. How does that work if you need a receiver to use speakers.

These speakers are passive speakers only ande requires an amplifier to make them work

Do I need a stereo to hook the speakers into? Or can I just play music directly from my pho e to the speakers

A stereo is required for the speakers to work

I have a ecoxgear soundbar on my rzr already, i want to know if i can connect them together in synchrony or if it has eco cast

No, the Pyle PLUTV47R does not feature EcoCast, and it cannot connect to your Ecoxgear soundbar wirelessly.

EcoCast is a proprietary wireless audio broadcasting technology exclusive to Ecoxgear products. Because the PLUTV47R consists of passive speakers (meaning they do not have a built-in Bluetooth receiver or internal amplifier), they cannot link to any wireless streaming network on their own.

How to Make Them Work Together:

To get these Pyle speakers to play in synchrony with your Ecoxgear soundbar, you will need to establish a physical, wired connection:

1. Add an Amplifier: Because these Pyle speakers are passive, you must first wire them to an external 12V marine-grade power amplifier hidden inside your RZR.

2. Use the Aux Audio Ports: Check your specific Ecoxgear soundbar for an Aux-Out (3.5mm or RCA) port. Run a physical audio cable from the soundbar's Aux-Out directly into the Aux-Input of the amplifier powering the Pyle speakers.

By wiring them this way, your Ecoxgear soundbar will act as the main Bluetooth controller, and it will physically pass the audio signal back to the Pyle speakers so they play at the exact same time.
