Yeah. It's not as bad as the reports make it sound, but it is weird. (Actually, I take that back. I've not yet gotten the balls to thrash my new car, but it exists to some extent at lower speeds, even in a straight line.) I've got an appointment on Thursday at the shop for them to upgrade the software that's supposed to fix that.

are you planning on using the factory speakers and amp?

That's what I'm hoping to do. I'm not 100% sure that the amp they refer to is external to the factory head unit, though. I might eventually see if I can create my own fascia to match the Volvo's dash a little better.

Have you driven the TSX? I test drove one and was terribly unimpressed. It's got a surprising lack of power for a car touted as a sport sedan, and the seats were the most uncomfortable I sat in amongst driving half a dozen or so sport sedans.
