[QUOTE="6r33n3y3z, post: 8853697, member: 689446"] I was wondering about that. I have an older amp that I want to hook up for mids and highs. The manual says the inputs are 200 mv - 2 volt. As you know most head units are now manufactured with 4 volt. They still make some 2 volt head units, but they seem be limited on features compared to the 4 volt and higher. I have not purchased a head unit yet. Can I use a head unit with 4 volt outputs on this amp and just turn the gains down?
