Okay, so I have the 1001-RB II (700w) and i use it with my 4x10 and 1x15 GLX cabinets. With both, i have 700w power handling. anyway, as some gigs require less or more sound, i decided both cabinets would be overkill for the smaller ones, so i decide it's best to bring only the 4x10 cabinet. I've done this for a while in small bars, but on sunday this week, im bringing the 4x10 and my head to church because of a internal problem in the church ampeg 115. And im just wondering, since my head is 700 watts, and the 4x10 is only 400 watts, it is possible to overload the cabinet at a certain volume and cause damage to the cabinet? all help appreciated. thanks so much.
