2018 Polaris GEM radio replacement

My factory-installed radio (Lightning Audio-1500BT) died and I need a replacement and hopefully upgrade to better model. The model installed is only 4 inches deep but I think I need a larger (i.e. deeper) radio. Has anyone upgraded their radio? If so, what brand/model did you go to and how did you overcome the welded bracket that limits the depth of the radio?

I put this one in my 16", is is less than 4" deep. Fit perfectly. It is not going to rock the stage but it works for a golf cart.

I use the Sony MEX-BT100 it’s a Powerfull single Bluetooth head unit. Check out all the reviews on it. It’s got some serious power for a indash stereo.

This is the 100 watt unit. They have a cheeper 50 watt unit
