new to me 07 torrent questions

[stretch8668]

I just purchased a 07 torrent with 91000 miles car runs great drives good. Is there anything I need to know about these cars what should I do to (maintence wise). It also has the pioneer stereo with subwoofer is it possible to upgrade the subwoofer and amp also what size speakers are in it. I plan on giving it a tune up and put a cai on it and other personal touches.

follow the maintenance plan in the owners manual provided below. Better off doing things earlier than later. Check this site for you options on stereo upgrades www.crutchfield.com . Lots of luck with your new vehicle.

Crutchfield doesn't list anything for factory sub already checked.
