1. When is a Line Driver needed? My HU (Kenwood DNX 7100) has only 2v out.
2. What brand is the best?
3. Do these devices have any other features like EQ, etc. that would help justify the expense and install?
4. Would you put one in? Or are they a pain and hardly ever help?
...I travel 18 states for my job and listen mostly to AAIF, AAC ...basically all uncompressed audio from my Creative Zen 30GB wide view (sweet pc).
Speakers are sr6500's front AND rear! Still trying to figure out my sub issue.
