I had my Alpine SPX-F17M and F13M isntalled on the kick panel, and the sound sucks on both sets.....The sound from stock door location with tweeter in the kick panel facing the rear of the car sounds a lot better.....of course, deadening and sound absorbing in the door too(every hole is covered up), so that the door doesn't rattle at all.
Here's the result I got from Q-form: the left speaker sounds like coming from a cave, with tons of reflection. The right speaker sounds so loud that the whole sound stage seems pulling to the right. Since the F17M/F13M crossover is adjustable, I tried every possible settings, time correction, and even reversing phase, not helping at all. Anybody has any idea?
Otherwise, I will keep my speakers in the door, and try to compensate the loss of high freq on the woofer from the tweeter on the left side, and cutting freq from passenger side tweeter to compensate for the higher freq on the woofer produced.

its possible your speakers are designed to perform better off axis. its a rare car audio speaker that is sold designed to be used completely on axis.
however, in this case, I believe there are other factors at work here. possibly resonance of the Q-forms, maybe the crossover settings, I dont know.
But ive seen Q-forms in many instances take their owners very far in SQ competition, so its definitely not your Q-forms as a statement about either the company or this product in general.
could your specific Q-form be a dud? maybe, but id check the tuning first to see if there was anything I had missed.
The resonance of Q-form? Do you mean the back wave?
Nah....I think it's the car's characteristics anyway....
I have the same speaker and different speaker with a box to put into kick panel and still sound like shit....I tried tunning, angle rotating, and some other method with the box(not Q-form) in the kick panel....still, sound like shit, especially on the driver's side.....
Now I am thinking if the space under the dash is an issue....
I chatted with another guy in Canada with a 99 Si and he said he had more under-dash space than I do, in term of the height from the floor to the lower dash cover(cover removed).
cant be characteristics or speaker locations, Ive run two different builds of custom kickpanels in my car, and both sound amazing from a staging point of view
i know when mine came from qlogic they were flimsy, now after a few layers of glass and a can of rubberized undercoating ont he back, nd recrpeting the front, i can step on them and they wont break

thank you.
May be 03 Vic is different!?
Anyway, I can now run 3-way passive without anyway problem, one speaker in door, 2 in Q-form. Stage set, and nicely sounded. At least not from a cave.
