Which would you guys do???

[rjay 10+ year member]

I've got a 09 Nissan Sentra. I am trying decide if I want to do a 5 channel amp and run all my speakers and 10" sub, or a 4 channel amp and run front set of components (leave the rear deck speakers connected to HU) and my sub. I just know I want a single amp set up. Would it be a problem running the rear speakers on my HU (aftermarket not stock) and the fronts off the amp, or just not connect the rear speakers? I just want whoever would be in the back seat to easily hear the music when it's at a lower volume. Don't have any speakers in mind, I'm just trying to figure out the amp configuration first! Thanks

Either will work. Depends on how much power you're needing and at what load. Most 4 channels are only stable to 4ohm bridged. A 5 channel would give you some flexibility with the coil configuration of the sub.
