This is my first post, but I have been lurking around the forums reading
as much as I could in order to learn as much as I needed, but did not
quite get an answer I was looking for. But yea I just got my Maxima
SE-L with Bose about 1-2 months ago and I've been planning to work on
the stereo.

Right now, I see my choices as-

1) Get a new HU and a PAC kit(ROEM-NIS2, so the aftermarket HU can work
with the Bose speakers/amps)
or
2) Get a new HU and some how dish some money for new speakers

But my main concern is the HU(I want one that pretty much plays MP3's
and CD's). I know I should try and look for one with 4v preamp outputs,
but those HU's tend to be out of my price range(Dont offer Eclipse
because in my area, well what can I say, people tend to "want" alot of
stuff for a five finger discount) and I would like the 22+watts RMS
coming from the HU because I don't think I'm getting new speakers and
an amp to run them anytime soon.

My price range is pretty much $200-300 and I've been looking into the
Kenwood Excelon KDC-X579 and the Pioneer DEH-P7600MP. and I do, well
from what I've heard that the Pioner Premier name and price, is well,
just for the name, correct me if I am wrong.

If anyone has any other suggestions or has experienced these two HU's,
I would appreciate it if I was enlightened by your
opinions/experiences.

Right now, my path is probably going to be getting the new HU with the
PAC kit.

Then I would want to add some subs with an amp

oo and I ran into this today - the Pioneer DEHP8MP

heres a link-

from what I understand, it's pushing 10 more watts peak from the MOSFET
amp than the previous Pioneer HU I listed, would this be too much for
my speakers? Has anyone heard much of this new HU?

Thanks for the help guys
