long time bass enthusiast long time forum reader finally had a unique enuff question to ask.. still waitin for response. drive a 98 subaru legacy gt limited, got TWO oldskool 12' 300w rms cadence q drive's and i am currently waiting for my TWO new cadence 600w rms amps.. hence my question is it ok to hook those up together if i keep the gain down???
