After trying to find a way to fix a REL Studio II plate amp (300 watts), I am thinking of just replacing the amp with a new one that is housed outside the enclosure and wired through the plate to the drivers. Can someone recommend a high quality amp (similar power) that has some of the controls the REL has? I won't be able to use the high impedance inputs REL is famous for, but having this sub work again would be great.
