Speaker's fitted professionally. However drained my new battery so had to pay for an additional on/off switch. Sound quite loud but could do with a lot more bass. Also impossible to register warranty as American company.

So far so good, time will tell about long term durability Installed into a Honda pioneer 1000 I needed to purchase clamps that would fit the 1 3/4 roll bar as the clamps that come with the speakers are only meant for motorcycle or ATV handlebars As many have said the speaker wires are short. I fixed this by using regular speaker wire and some heat shrink electrical splice connectors to make the wires long enough to run to under the front hood The unit itself is small enough and mounts neatly and easily under the hood. Everything works good and though the unit has no bass, the treble is really nice and it pumps some really good sound *4 year update* Still running strong with no issues
