Bom dia! Preciso de ajuda, espero estar postando no local correto. Montei um sistema. CD Player Pioneer DEH-P4180SD provisório até chegar o Kenwood KDC-X996 Amplificador Alpine PDX-V9 5 canais Front - Kit 2 vias Focal Access 165 a1 Rear - Coaxial Focal Access 165 ca1 Subwoofer - Jlaudio 12w3v3-2 RCA - Stinger 4000 O problema foi o seguinte, o som já estava bom com o player Pioneer DEH-P4180SD saída 2v, o ganho do módulo estava regulado em 40% stereo e mono, ao instalar o novo player kenwood KDC-X996 saída 4v a qualidade do Stereo sumiu, o som está abafado, o player possui diversas regulagens, porém não consegui melhoras, o ganho do módulo também já alterei, para mais e para menos e também não houve melhoras, o Mono está tocando bem, o volume do player vai de 0 a 35, porém não há diferença por Ex. do volume 20 ao máximo 35, seria somente o ganho o problema ? Segue abaixo as especificações do Player e Amplificador.
