i think we should add power ratio to this also. i always liked going 4:1, sub power:highs power
sadly im going 4x18s to 4x6.5 and 4xtweets
power ratio is bad 11200:300
i never cruse around with my subs at full tilt, just at comp. daily driving i keep my subs low enough to balance out my highs. its loud enough for my daily driving.
