I found these hidden in my basement. I havent used them in like 10 years. Designed for pick up trucks, stand up behind the seat. I guess you could mount them anywhere. I had them in my Jeep CJ on the back wheel wells.
They sound really good for what they are. Says 150w max music power.
The mounting system is broken off the back, someone tried stealing them from my open jeep. Looking for $50.00
