Hey, I just bought a 2007 HHR, and was wondering if you guys could give me some subwoofer/stereo ideas. I want to keep the space usable, and want to know if you guys have done. Thanks!

My HHR is all stock. About the only place for a subwoofer box is in back of the back seats, which will take up space.

I'm thinking about what I want to get in my HHR too. Too many ideas at the moment.

If I were you though, I would go to Crutchfield.com, get the phone number and talk with an advisor. They are very good with helping pick the right equipment to suit your audio needs.
