Hey I've got a MTX 895 5 channel amp and i want to get two mtx thunder 6000 12 inch subs. Do yall think I could put these on my sub channel of my amp?(b/c I've got the other channels filled with two 6 1/2 inch and two 4" speakers) Also, i jsut made a sealed box that has an internal volume of 2.5 ft^3 will this work?
