Thanks again guys for the advice, it is much appreciated.
I tried to keep the woofers as far as possible from the driver's/passenger's ears in attempt to maintain as equal pathlengths as possible (within reason as space and pedal position restricts this to a degree). Hopefully this will keep the imaging tight, and eliminate frequency shift and separation.
This is partially why I ended up going with the Alpine 9833 HU as it has time alignment facility - not something that I would want to mess about with too much to adversely affect the SQ for passenger/s...but may be a handy feature to correct for the differences in pathlengths.
The tweeters down low may result in a slightly lower stage height, hence why I've tried to keep them as high as possible (within reason again). Hopefully it won't be too noticable, and without installing some abient tweeters to raise the stage height, its something that I probably won't be able to overcome all together. I wouldn't want to move the current tweeter further up though as it creates other problems (freq separation and bigger differences in pathlengths).
Once I get the preliminary placement issues sorted out and the actual hardware installed (still have to rewire the whole car remember! - will be using optima yellow top batt by the way)...I will be taking it to a reputable (lots of feedback and input on car audio forums and in person) installer (shop) to have it all tuned so that should help.
I am an Audiologist (fit hearing aids, perform hearing assessments etc) and some of the similarities with car audio are quite cool, some of the things I've learned through reading about car audio has helped me in my job, and vice versa!
This arvo I will put the seats back in temporarily (may even pick up a cheap laser pointer) and have a closer look at woofer/tweeter placement before I glass the outer skin!
Cheers again
Alan :agree:
