Help Hartke 4x10 cab vibrates!!!!!

[Langueta]

Hi 2 days ago I Played for 200 people in a pub I was using 300 watts and I think that I would need another cab. Yesterday I ve bought a hatke 1x15xl..I will connect both with a gallien kruger 1001rb2 bass head.
If the head has 700 watts and both cabs together 600 watts
I can use the head at full volumer???Or it will damage the cabs


Other suggestion I have is why when I play in my studio the 4x10 cab vibrates when it is exposed to low volumes...Why not when I played live the other day. ...I was thinking that could happen because the acustic is not so good so the sound bounds and goes to the lid of the cab...When I press the lid with my hand it stop vibrating
Thanks

When you say the cab "vibrates", do you mean that the sound is distorted?

i think you mean your cab is rattling?

cuz vibration is what produces sound, and I generally like to hope my cab vibrates.

No, the lid of the cab vibrates, the front part...where it says hartke 4x10...When I put my hand to the lid the vibration stop..Moreover when I play trouhh the amp in my house and when I played live the lid dont vibrate......very strange. What do you think about it
