JensenJXHD35 Heavy Duty 3.5" MINI Weatherproof Surface Mount Speakers (1 Pair), Black

Nothing

They are okay for use in my bobcat. Not much depth but i expected that and they are Heavy duty outdoor rated, so they are very good when you consider the environment they are used in.

Easy to install, sturdy construction and sound great. Don't expect too much bass from these due to their size (I mounted them in a "glove box" type enclosure on a golf cart which acted like a speaker box improving the depth of the sound) but they sound great anyway.

We bought these for our golf cart. They sound pretty good & they are small & compact. We didn't want to drill holes in our cart so the brackets are great other than the metal is very tough unless you need it to be. Reasonable shipping time & price

ask me again come spring and I be able to tell you if they work good there on a motorcycle and it been snow here

Obviously, these speakers are small and having read the reviews before purchase, my expectations were not real high. The speakers are average at best. I bought these to use in a trailer I use at the drag races. They will be fine for what purpose they were purchased. Just turn the bass down very low and they are ok.

These could sound better.not a lot of bass

For a name brand speaker the sound quality is absolutely terrible.
