Need help with selecting head unit

[cheezer82]

I've been looking to replace the stock stereo on my vehicle, however im not sure what to get.

The thing is that my car has 7 speakers with an integrated subwoofer, and the stereos that ive seen have 4 chanels how would i go about connecting all of the speakers to a 4 chanel stereo.
Would I loose two speakers and the sub?

I am looking to set up the new system with a
Kenwood X895 head unit
Kenwood amp KAC 9105D
Two 10' Rockford Fosgate P3D2-10.

I was also thinkning of changing the stock speakers to the
-Rockford Fosgate Punch P1653 (X6) if possible.

Any help I would really appreciate it.

Thank you in advance.

Your car has a factory amplifier. If you list your year, make, and model I can look up the adapter you'll need to install an aftermarket radio.

I would suggest the Kenwood DDX419 for you.. It's about $400 but it's well worth the money, and it has everything that you need. I'm about to order the DDX319 (a step down from the 419, has everything the 419 has except for bluetooth) for $350. Plus it's brand new with an available 3 year warranty for like $30 extra. I believe I am correct about the bluetooth options and stuff like that.. I don't really care about the bluetooth which is why I'm going with the DDX319. I'm a fan of all Kenwood products though.
