So here are my plans. Would love some input. Vehicle is a 2012 Armada w/ Bose.

I have an MS8 to integrate with the factory HU. I plan to use the onboard MS8 amps to power speakers, 2 ohm nominal (other than sub). The fronts are JBL P660c. I am hoping to run these active and leave out the external crossover box. I have a JBL 328 for the center and a pair of JBL 608C's for the rear doors. I would use the crossover with these since I only have 8 channels.
So that is 7 channels, 5 front, 2 rear and the 8th channel will run to a sub amp in the back. Any comments or suggestions are welcome!

the ms8 really doesn't have enough power to do front midbass justice, nore do I feel it would do well with the center as depending on material playing back, center gets a hell of a lot of sonic info. Consider a five channel amp instead of a monoblock for sub only, one that you can run the 660c woofers on two channels of, and use a third for the center. This wastes a channel but I cant really see a more practical way, perhaps use the fourth channel for the navigation voice? I don't know on your car but some pipe this spoken output to different speakers than the main stereo ones.

Thanks much for your input! So I purchased an Alp MRX V70 5 channel amp. The 5th channel will power the sub and I'll sell the Power Acoustic mono amp.
I definitely will power the 660 woofers with the amp and run the tweets from the MS8. Should I run the rear 608's from the amp, or as you suggest, amp the center speaker and waste a channel (no biggie)? It is only a 3.5 (2 ohm) center. It will get 30 wpch from the MS8. It will sound inadequate running off the MS8?
