Ok well I am interested in these two systems but i don't know which one is better for a kid i like bass/subwoofer and also nice great sounding quality. But I also like durability I have heard that the panasonic breaks a little to easy while the sony is great with great quality but not as high wattage on the subwoofer. I just need someones because i don't want to waste my money on one of these systems thank you

P.S. I WILL ALSO TAKE ANY RECOMADATIONS TO OTHER SYSTEMS thanks
