Hi all-
This is semi-OT; I'm working up a 'system' for my Buick.
I've got a Profile 3channel amp, 2x75w + 1x150w (all RMS)
for the back. This will be running a 12" sub (80hz low
pass) and a pair of 6x9's (120hz high pass, optional).
My question relates to the quality and specs of 6x9's I
need; The amp puts out 2x75 RMS, 2x150 peak, at four ohms.
Most 6x9's I've seen range from 40-60watts RMS; 100-200-
300 maximum watt ratings. Frequency response varies from
20hz-20K to 40hz-38K and everything in between.
As the sub is going to pick up the low stuff, I was planning
to cross the 6x9's over at 120hz. Now, if I do that, the
lion's share of the power (which AFAIK comes from the low
frequencies), will not be passed on to the speakers; which
would lower my power handling requirement from the 6x9's.
Right?
If that's the case, and I don't use the 6x9's for bass,
then I figger a decent set (~$90-100) would be plenty to
do the mids and highs. Sound okay? (that's sony, pioneer,
kenwood, etc.) (and if I put nice seperates up front, I'll
get most of the highs from them, meaning the 6x9's are just
for volume and basic full range fill.)
However, I don't HAVE to crossover the 6x9's, and who
knows, it might work out well to have them do full-range
sound. So maybe the 6x9's need to be able to handle the
full 75 RMS and have good low-frequency response. That
puts me in $150 territory, which is fine; but I'm trying
to stay as inexpensive as possible. (that's infiniti and
polk as near as I can tell)
Not a lot of room for that much 'stuff' in a roadster,
but maybe someone has some experience with other cars to
fall back on?
TIA-
Kyle
