As someone who isn't very knowledgeable in the audio world I dedicated a lot of time into doing extensive research on the best audio equipment for my UTV before making my purchase. Through that research, I came to the conclusion that my best bet would be DS18. BOY am I glad I went with DS18. This stuff is LOUD! All my buddies are envious of how loud my Side by Side is compared to their other brand audio equipment. Rumor has it, every squirrel within a mile radius are plotting a lawsuit for hearing loss. These things are so LOUD they brought Bigfoot out of hiding. Not only are they LOUD, they are DURABLE. These things have survived the elements, the rough terrain, and my singing. I'm tellin ya, these things attract more attention than a UFO sighting. I ain't lyin', these have more bass than a fishing tournament!
