I haven't had the seat down much. I will have a potential problem, say, if I want to put skiis through the back seat area, over the amp. I'll have to put a blanked or something over the amp, and not overheat it.
When adding an amp, I guess it depends which space you want to lose. Side area, or back area. I'm sure a creative installation team can give you some suggestions.

 

Just wanted to back what al503 said.

There is definately NOT a sub under the back seat.

to double check this for your self, simply grab the front of the seat and pull up firmly. The bottom os the back seat just clips in the front area. And then just look for yourself.

Sub under the backseat????? Which dealership told you this? At least you now know where NOT to take your car in for service.....Take your G in for an oil change and you might return to have tricycle tires mounted....lol

 

To match the stock impedence rating of the Bose headunit, look into the Image Dynamics ID62 comp set. I believe they can be had with a 2ohm mid and a 4 ohm tweeter. This would allow you to run them off of the stock Bose amp if you wished to.

 

Most component sets are 4 ohms and you should have no problems running them off the stock amp if needed. The only time you really need to worry about the ohm ratings is when impedence of the speaker is less than than the minimum impedence of the amp. IE: if an amp is only good down to 4 ohms and you try to run a 2 ohm speaker or sub, you might have problems. Running a 4 ohm speaker with an amp that is given it's nominal/max watt rating at say 2 ohms will only cut the amps power down by half. There is no real danger here, just a loss of power.
