I used to have an ok system in an old Saab. The highlight was the JL Audio MicroSub, driven by an Alpine amp. That little subwoofer was very musical and packed a nice small punch. Not enough to rattle any windows, but it really made the rest of the system (I think I had JBL speakers) sound so much better.
Car Audio Speakers
I know this rarely if ever pops up on Agon. But I'm in the market for speakers for my car. Anyone have any experience with high quality car audio speaker brands that can rival audiophile speakers? I'm pretty clueless. Most of my experience in car audio comes from those idiots who blast their distorted one note hip hop/rap bass at an intersection on weekend nights.
