    Re: Help with German Maestro SV 6509s

    could be phase issues.

    what vehicle?
    what headunit?
    how wired (new or factory)?

    1. if some are out of phase with others they will sound weird.
    2. if you didn't adequately seal the openings and speakers they will sound hollow. i use weatherstripping foam on front and back of each speaker to seal against the door panel and door metal, respectively.
    3. head unit amplifiers are small and low power. external amps are key, but only after the above are resolved.



    have you been helped by me? i'd love to know. shoot me a PM.
