Infinity Reference Speakers with Stock Head Unit in 99 Accord Part 1

20hz? no way. You might be able to see the speakers moving, but it takes a substantial cone area to have any audible representation of 20hz. 45hz and 60hz may mildly improve. honestly the most likely improvement you'll find is in clarity/loudness in the mid to high range. stock head units just don't push bass notes very well. the double tweets (possibly at half the omh load of your stock speakers) may well increase upper range loudness though. let us know how it goes.

in addition i feel i aught to mention that i do have a little experience with this sort of thing. before i upgraded to a 4ch amplifier or changed out my head unit i switched out the rear door speakers in my blazer for Polk db651s... imho polk speakers are made for midbass and are very efficient at producing it and i noticed a substantial improvement in that sense even off the bone stock head unit. i've since upgraded w/ kenwood head unit, 2 more sets of components, and a 500w 4ch amp. WORTH IT.

@tonythephatone I agree with your comments and expect that to be the likely result. I still like to quantify things though. The sweep from 20hz to 20khz is pretty standard as that is the range of human hearing at birth but as you say I don't expect much content at such low frequencies from this size speaker and space.
