Im running a kenwood kdc deck I think it has over 3.5 volts going to a audiocontrol Four.1 i Eq which is able to push voltage up to 13, if it then goes to a kenwood kds-p110 digital processor unit which has only 1-2 volts is there a way to push that voltage back up for the signal? Does the benefits of having a high signal voltage matter so much as that I should eliminate my 1-2 volt processor?
