Simply put larger the trunk thicker and heavy the lower octaves sound plus the notes feel lethargic.

2) A direct input to the cars interior is the best approach for best overall SQ but not necessarily what some people want in the bass tone ( to flat sounding to their ears )


D.

I tend to disagree with 2) - i have tried various ways and in a sedan as close to the opening of the trunk face rear is the best in most situation, least cancellation of bass.
