Right now I have 1 15" Avalanche in a 3.5ft^3 box tuned to 27 htz powered by an Orion HCCA 250 G5. Is there anything I can change or get to make the sub louder?
Louder? I dont kow about you but I am running the ava 15 in a 2.5 sealed with the orion 250g4 and it is extremely loud if you want louder try an spl sub not a SQL sub.
if you want louder try an spl sub not a SQL sub.
