## Description

Great Product

Review: Sound is good. They do tend to overdrive when the volume is increased but it is very loud at that point. I bought them to use outside and haven't beanpole to do that yet due to weather. Inside they work great
Review: I own a 2015 KZ 20RBS with a Jensen Stereo/DVD player and have been disappointed in the sound of the system since it was new. The A-channel are the two cheapy inside ceiling mounted speakers and the C-channel are the outdoor speakers. Channel B was unused. I decided that I wanted to fix it where the TV would work through the stereo (The DVD would work through the speakers but not the TV) Head scratch ?? Since I was working with the system I decided that I would utilize Channel B and make the sound more full. Enter the BOSS 4.3" speaker set !!! I just got done installing them in the trailer and they sound amazing. I have a pretty good ear since I have been a musician for years and these little guys have an incredible frequency response with crisp highs full mid-range and surprisingly deep responsive bass. I couldn't be happier especially for the price. These speakers are a perfect combination for the Stereos that come in most Travel Trailers. They are well made and super easy to mount. ****Note I'm a person that likes to listen to music and movies at a medium volume level so I'm not sure how they would hold up if "cranked up". They are rated @ 200 watts but I've always only fed speakers half of their rated amount.
