I don't see why not. You should be fine as long as you don't bang 100% of the time.
Edit: I got 2500 to 2600 watts to two 600 watt rms subs. They get a little warm after banging out a 4 min. song, so I let them cool off and try it again.
If you guys remember Derrick already has two 18's.....So that would make 14..... Plus he was selling his bro's T4k's.
Nope, its not Derrick...
Sorry people...
Here is a tip for you.... point the box forward or up. Push the box all the way back against the taillights. If you have to point it back get it as close to the back of the car as possible. Leave enough room for sub excursion and yes I know it will block some of the port but it is louder.
Edit: I know a little something about getting our body style Altimas loud.
I would recommend two Sundown Z15's. There on pre-sale right now. They are some tough ass subs. Check it out...
