: Question on installing Aftermarket Sub in CTS

03-23-09, 07:37 PM
I have an '05 CTS with the Bose sound system and would like to swap out the Bose sub under my rear window with an aftermarket sub. The sub that I want to put in is 10" 1000 watt Rockford Fosgate. I'm assuming that it will fit, but if I need to make a new base to bolt it to if it doesn't match up with bose sub bolts that's no problem. Do any of you know if the sound system that the CTS has is already powerful to make my fosgate sub pound pretty good or will I need to install the amp too?

It all depends on the facotry sub rms wattage and the ohms of the sub. Bose is usually at 1 ohm so you have to match it to get the best out nof your sub so test wire so u don't waste ur time and make a mount and it doesn't fit
