I just finished installing a new premier deh-p360 hu, eclipse amp, and eclipse 6.5 3-ways in my doors. (Something that I'm pretty proud of actually, being my first install ) Now I have a dilemma. I'm not sure whether or not to install my 6x9s in the back OR just run fronts and a sub (which I don't have yet) OR both. Any suggestions?

Also, would there be any problems if I used my amp to power the fronts AND a sub? I'm thinking that if I did put both the 6x9s and the sub, I can use 1 amp to power the fronts and sub while I'm saving money to buy a mono amp for the sub. The amp is 4x50 RMS at 4 ohms and 4x70 RMS at 2 ohms. I think I could bridge 2 channels for 140 RMS at 2 ohms to run one sub. Would that be enough power for any 2-ohm stable sub? Maybe a DVC sub?

Thanks.

It comes down to personal preference. I really don't care much about rear speakers, so I don't use them. I have a 9833 alpine, and component speakers up front so I have them bi amped, and it sounds amazing. I've had people telling me it sounds much better than any front/rear setup.

I have you setup, amping fronts and bridging a pair to power a sub. About the same wattage too, everything sounds great, I have a lot of the sound faded to the front anyhow, I don't like too much sound coming from behind me either.
