RockvilleRGHR2 Marine Gauge Hole Receiver, Bluetooth/USB/AM/FM, TDA7851L Amp, 288W Peak (72W x 4), IP66 Waterproof, Wired Remote, for Boats/ATVs/UTVs

Nice loud system with good bass (I like the +7 setting for bass). Don't need a subwoofer - could feel the bass through my legs on the front seats. Bluetooth worked fine with an Android Pixel 2 phone (I tested that I could walk 50 feet away and it still was working), and the USB worked fine with an old 8 GB FAT32 thumb drive that I had laying around.I had to enlarge the hole in the dash where the original Clarion stereo was - couldn't use a hole saw because a hole already existed (see pics). I just drilled dozens of small holes to enlarge the original hole. System didn't power on at first because I didn't connect the yellow wire to the accessory switch. I decided to connect the yellow accessory wire to the red wire so it is always powered on when the battery switch is turned on (this is fine because I always turn my battery off when not using the boat). I didn't want any issues so I ran 12 gauge duplex tinned marine wire from a fused battery circuit to the Rockville receiver - dedicated circuit. (see pic) Also, I ran 14 gauge duplex tinned marine wire to all speakers. The 13 year old speakers work just fine - can't find anything wrong with them so I won't replace them.Went out on the lake a couple of days ago and floated in the middle while cleaning the interior. Ran the system for an hour. No problems so far. Cranked it up to top volume of 40 briefly just to test it, but mostly while stopped I had the volume between 10 and 20.

I have purchased a few items from Rockville for different vehicles. This head unit is for my pontoon. EASY install and great sound (even without an amp). I do have a powered sub (rockville) too.. which makes my boat sound awesome! ***** ON THE CHEAP!!

The media could not be loaded. I have used this for 3 days and the buttons are starting to break and get stuck. Unless you pushed them in the right spot they barely worked too. Incredibly disappointed in the durability of the radio. The plastic screen cover is still on it.

The product Seems to be quality and sounds really great. The chrome bezel was a bear to remove and actually broke upon removal. They don’t make it easy to get off for installation.

Great head unit for the boat! It is easy to wire and use and really puts some power to the speakers without an amp even. Can’t go wrong with this head unit from what I have seen so far.The hole was needed to be enlarged for mounting compared to the clarion head unit it replaced.For all the 1-star reviews saying this unit doesn’t work... there are 2 power wires that you need to connect to power. The main red wire and the yellow memory wire. If you do not put power to the yellow memory wire, the unit will not power on.I’m very impressed with this head unit so far and it blows away the clarion I had in the boat previously. I don’t think I’ll even add an amp, it powers the kicker 8” speakers wonderfully!

Purchased this unit a few months ago. Just today finally was able to have it installed. Unfortunately, the unit is completely dead. Everything is verified correct as was the 12V power source. Both the Red accessory and Yellow power wires connected to Pos source. Black wire connected to Gnd. Tried to connect directly to a fresh 12V battery to confirm. Still completely dead. The install guy said he saw the same thing happen to another customer who ordered one. Tried to return to Amazon but past their 30 day policy. Trying to contact the seller through Amazon Chat. Hopefully, can get some resolution.

Sometimes it goes haywire does its own thing like jump modes while you’re listening to music. Or doesn’t pick up someone’s Bluetooth it has to be reset / fuse taken out and put back to refresh

Nice compact unit weather proof installed in my military humvee
