i need a good sound cuality amp that can overpower the noise of a drum kit

i need suggestions on witch amp to get
yeah, try an acoustic guitar amp with an XLR input. Crate and behringer have some low cost units, try them out.
Just watch out for Behringer, they tend to advertise their peak wattage instead of RMS.
