i know the recommended farad per wattage ratio.. but im working in a tight space and i wondered if adding any sort of capacitor like a .5F to a 1500rms system would prove some usefullness or would it be more of a hinderence? I already have a HO Alt so i got a decent flow of juice coming.. but let me know your thoughts.. the cap im looking at is the Harrison Labs .5F which is only 2.5 x 4.5.
