What components are u using ? Stock speakers ? Anyway yes dsp with can run ur component. If want to run ur sub then u need a 5 channel amp but since ur sub is a 12 incher then better u stil retain ur current amp for sub. Use the dsp with amp to run component and use ur dsp to tweak the sun but run that off its own mono block. Anyway u will need a good tuner for dsp. Everyone out there konon konon the best. All will cucuk the previous tuner and say wiring all wrong and bla bla bla that only they could have fixed the problem.
