Good alternate to cutting the parcel shelf, though being stuck down behind the seat won't do much for sound volume or frequencies above about 3khz...which is the top end of midrange anyway.
Isn't the whole point of 6x9's to take up that midrange where the sub and fronts can't go in terms of frequency?
So still no answers as to how to get some holes cut behind the seats? Anyone done it before?
Well there's the inherent problem with 6x9's. You'll rarely find a decent well thought through system with 6x9's as they do high sensitivities to midrange (ie comparatively louder), which in effect pulls the whole sound to the rear of the car. When was the last time you went to a concert and stood with your back to the stage? Music is meant to originate from in front of the listener, with rear fill provided by speakers with substantially less power output.
In a car environment, the goal is to provide an even spectrum of midbass-high frequencies (80-20,000hz) from the front, with the sub in the rear (<80hz) with rear fill provided in the back in the range of 80-4,000hz with 6-12db (about half to quarter) of the SPL of the front. For example if I was powering the front splits with a 100wRMS/channel amp I'd probably run 6x9's off 20wRMS, or even the headunit. Even then it would need a whole lot of tuning to get the balance right.
