Weak String Sound

[adams83]

I need help regarding a '97 Fender Standard Jazz Bass string sound problem. My E and A string sound is great but my D and G almost sound flat/weak when I play? Changed strings but still sound same. I have it set-up with Roundwound strings at the moment. Any and all help is greatly appricated!
