: Rear deck speaker for 05 CTS

What is the size of the rear deck speaker for a non Bose system and also the size of rear deck for a Bose system.

I looked through Crutchfield and only found front and rear door speaker sizes.

Any suggestions for speaker options while keeping the factory head unit.

thanx stillen

I believe it a 10'' sub in the back with Bose system having two of these and a different ohms as well

Only one 10" and it just under so if you use an Infinity 10" you will need to remove some material from the ID to make it fit.

keep in mind you can use a 2ohm DVC sub and wire it down to 1ohm just like the bose unit.
