Right out of the box, the speakers are heavy and solid. All the wiring is there with quick connects and labels on everything. I had to splice every wire to make this work on my cart, but that is not the manufacturer's fault. This was the first stereo I have wired, and even with the cutting and splicing of wires, this was a relative breeze. I spent about 5 hours putting this all in, with 2 hours of that just making sure I was doing stuff right. I wired everything to a switch and back to the amp. Again, never done this before, but nothing to it!!
4 speakers are pretty loud. Half volume on the knob is easily enough to overpower the 39 year old 2 stroke engine. 3/4 volume and you can't hear your passenger. I am sure I will be heard right across the whole course if I wanted to be.
There is not a whole lot of bass, but it is a 3" speaker so it won't be breaking any spl records. The music is clear. It goes loud and still stays acceptabley distortion free.
There was a little bit of background noise through the bluetooth connection that was not as noticeable with the wired aux port. This thing picked up the bluetooth on my phone within seconds of me first turning the power on. I literally did nothing and my phone was connected.
I would recommend this to anyone looking for a decent sounding, budget friendly stereo system. I am sorry I looked at so many different products all summer when I just should have ordered this all along. I will be ordering a second set for another cart I have.
