hello sinstealer,
carnival 6, adequate bass for music....again for video, sub is a must, somtimes a pair(subs
) maximum effects!!!
more wattage...... tighter bass, finer mids and highs......clean/quiet amps,speaks,sources.
noisy amps/speaks/sources...more wattage, more noise.
not sure about the carnivals paired with the nad.....most likely okay din naman. nad is a good brand.
wattage to drive the 6s???..... more than the minimum required would be a better option.
listen,listen,listen.take your time and enjoy listening.
good day
