So I recently purchased a used aguilar db750 with an aguilar GS 4x10. I'm pretty new to owning equipment seeing that I have always borrowed gear so I don't know my way around. When I start to crank it the cab seems to not be able to handle very much. You can't even hear me when the full band plays. When I turn it up, it starts to get distorted like the driver is about to blow. I plugged it into an ampeg 6x10 and it is immensely louder.. The ampeg is really beat up and not great condition so I'm lost as to what is wrong. There isn't any crackling so I wasn't sure if a driver was blown already or not in the GS.. I'm so lost.
