DS18 BTTWO Bluetooth Receiver - IP65 Waterproof Rated, BT 4.0, Remote Trigger Output, Stero Male RCA Output - Allows Connect & Play Integration to Your Audio Device

I currently have this installed in it's third vehicle. It's an easy install (and removal) and is a great solution to add life to, or bypass, your old worn out head unit. It's also stood up to time and being installed and remove multiple times and doesn't show any signs of giving up.The best part is it's easy and clear Bluetooth connection with all of my devices as well as the audio quality it delivers to the amp.

Works great, never had an issues with connecting

The first one I got was so used it was ridiculous. Burnt wires and solder on ends. I didn't even try to use it it was so bad. I ordered a replacement immediately. The one I received, was brand new. I tested it with voltmeter verified connections, and could not get anything out of it. Since there's no LED or anyway to verify that the unit is at least powered on, the only way is by trying to find a Bluetooth signal from it. I tried my Galaxy s22 ultra, my wife's s21 and my Carpuride to find any BT signal. NONE. So ANOTHER broken one. I didn't bother contacting their customer support, as my faith in the product was already shattered, so I can't comment on that. BUYER BEWARE.

Update- Great product-This product is great my first one damaged well due to improper installation. The blue wire is no a remote IN . It’s a remote out. Once sound is detected it will turned on your amp . please do not connect the blue wire to your radio .I have it paired to my phone and it works like a charm just follow the instructions very important that you do and you understand what remote out is . 5 starsMy old review .This is junk it only work for a day and after that it wouldn’t power on . I really had good hopes for it . Don’t waste your money.

I’m running an 800 watt 4 channel SounDigital EVOPS 800.4 with 2 6.5s and 2 8s on my rzr off of this. Sound quality and connectivity are great. I’ve tested range to 50+ feet with no issues. I didn’t want to spend $500+ on head unit and dash panel to mount a head unit. It has a feature that turns the remote power to the amp off when not actively playing music to save power that I’m undecided on. It only has 2 RCA outputs so I just ran aSplitter to get 4 channels. This thing is so small that finding a place to put it is so easy.

This is a great product. only one issue I had was that mine shorted out due to a faulty switch. it has a fuse for the battery but suggest another for switch

I have this connected directly to an amp to eliminate the radio in my classic Ford truck. I get in the truck, my phone connects, and the music plays. I use my Apple Watch to control the volume.

Quality is nice. It's well made and immediately fixed my issues with the stock SeaDoo Bluetooth unit. I have 3 amps on this unit and the RCA output is very good and I have no issues with any of the amps. The sound is nice and clear and no static like the stock unit.
