hello im building a sealed box for 2 q15 subs in my 1996 honda civic hatchback, i have a few questions? 1.... should i have each sub in seperate chambers or the same chamber? what is the pros and cons of doing either? 2.... what kind of difference in sound should there be between the largest recommended size encloser and somewhere inbetween? and whats the pros and cons of each? 3.... what kind of effect would there be having the subs down facing? Now for my front stage i want some more midbass, i have 2 different types of 6.5 inch woofers, infinity perfect 6.1 and older set of diamond audio hex series, i was thinking of putting the infinitys in the doors and getting some q-form kick panels for the diamond hex. what are your thoughts on this setup? i will have these crossed over at 80 herts, i dont have the tweeters anymore for these sets so i ordered some silk dome tweeters from parts express and hook the tweeters up to the crossover from the diamond set, then use the infinity perfect 6.1 woofers with their crossover without a tweeter, these two sets would be hooked up to a single stereo amp, what are your guys thoughts on this setup? should i have the infinity set powered by a seperate amp and use the built in crossover on the amp? well thanks for reading...... brian
