I purchase this system for a Christmas gift for my family . and I have not be disappoint . the system be easy to set-up and configure . the instruction be clear and efficient . with 650 watt I be not sure what to expect , but this system will rattle you window . I have crank this system way up and still have volume to go . the bass be incredible for such a small speaker -lrb- the speaker box be big though -rrb- . the input option on this system allow I to configure my setup the way that I want it with minimal effort . if you want a system that will give big bang for the buck , go with this one !
