Sounds fine for what it is a radio and 2 small speakers. If you plug phone into USB this won't charge phone but will play from flash drive (from my experience lots of radios won't charge phone) if you install to thin material unbolt wire clamp as in my pic. I'd say the big negative is no remote turn on if running amp so you'll need a separate switch to turn on and off amp.

Installation complete and I'm going to give this product four stars. I bought this radio and speakers kit to go into an aluminum fishing boat. I haven't had the boat on the water since the installation has been completed though. I will conduct a followup review of this product after the boat has gotten wet a few more times.

The radio and speakers arrived on time and there were no issues with the packaging. It was clear that I received a new item still in the original packaging.

Installation is pretty basic. Follow the instructions. I will say though that you certainly need to follow the speaker wiring diagram. In the instructions book, the top wiring diagram is intended for four speakers. Remember that this package only includes two speakers. You will need to follow the bottom wiring diagram if you only have two speakers. The bottom diagram is for a two-speakers bridged configuration. If you only have two speakers and wire them in an UN-bridged configuration, you will only receive HALF power from the radio. ... Remember, 2 Speakers = Bridged wiring configuration.

After installation, I must say that these speakers and radio sound very, very nice for being about $100. I mounted the speakers up towards the nose of the boat right underneath a little overhang. I think having them up underneath the overhang helps the sound. I've ran the radio for 8 hours one day and it didn't drain my deep cycle marine battery, and that was with LED interior lights on as well.

I will say that there is one thing I don't like about this radio. I know that it is probably meant to be a replacement for modern boats that already have a hole for a radio, but if you're installing into a boat that has never had a radio before, you will need to drill a really big whole to slide this unit into. The base of the radio is appx 3-4". Thats a big hole. I didn't really want to drill that big of a whole in my boat just in case this unit craps out and I need to remove it. I built a little box for the unit and drilled smaller holes to afix the box to the boat. Yeah, the box sticks out a little, but I can live with that.

I haven't tested the radio yet, because I haven't purchased and antenna yet. I have tested the Blue Tooth and I'll say that it connects excellently. I've bought BT crap from Amazon in the past and always hated fighting with getting it connected. This unit connected very quickly to my Wife's iPhone and has never dropped the connection. The BT connection is very strong and doen't break in or out. I've also tried the USB connection, and that too works very well. There is a 3.5mm jack for older devices that I haven't tried out and there are also RCA hookups that I ended up just cutting the head off because I didn't want to stick those fat heads through the smaller hole that I drilled, plus... who uses RCA connects these days anyways?

I connected the two Positive wires to a rocker switch mounted on the boat and ran a single positive wire from the other lead on the rocker switch back to the battery, which also has a master kill switch. The battery kill switch and the additional rocker switch give me piece of mind that this unit will not drain my battery by defect or by my forgetfulness in turning it off.

Again, very impressed thus far. Will have to wait until it's had a few lake trials. Will be putting in on fresh water. Will update this review afterwards.

Worked for my needs

Easy!

Installed on golf cart Sept 2021. Bluetooth stopped working in July 2022. Contacted Herdio about this and had a new unit delivered in 3 dats. Great customer service. As for the radio "¦ it's a hundred bucks including speakers"¦. Don't expect too much. Well worth the price for what you get.
