Bluetooth Amp Recommendations

I use my bluetooth earbuds synched to my S6 when driving to help with road noise and just because the factory radio isn't that good. I think a good solution would be to have a simple bluetooth amp that I could stream music from my phone to the factory speakers. I would like to know what some of you have installed in your own rides. Thanks for any suggestions.

I used the LG Tone bluetooth, like "Slingshot Garage" uses, for everything from mowing the grass to my morning walk and riding my Slingshot. They work great. I was Looking for a small amp to use when putting around town to listen to my music from my phone.
I haven't been able to sync my Galaxy S6 to the factory radio from day one. My wife's I-Phone has no problem. I was looking for a work-around to eliminate the factory radio for my music listening. The reason I need a work-around is I can't sync my phone and the factory radio. I use Spotify from my phone for all my music.
The manual outlines how to pair an I-Phone but never mentions an android phone. My infotainment screen never acknowledges my Samsung phone, whether bluetooth or usb. It says no device. Is it not compatible?

Only 2 that I know of if you want a pure set up out of the factory is Kenwood and Kicker. The rest you will have to piece together.

All I really want to do is get a small amp that I can wire into the existing speakers and then stream music from my phone. I could use bluetooth speakers but they are usually pretty big and cumbersome, and I already have the factory speakers. I think the ATV community probably has addressed this since most of those don't come with radios.

Thanks for the replies to my post. I think it's the Kenwood for me.
