Installed a Blaupunkt Woodstock a few weeks ago but still used the old speakers which were in the car as standard. Despite fiddling with the graphic equaliser and audio settings the bass is not really what I would like. However I don't know whether to upgrade the speakers to 2-way or 3-way with better woofers or go for a sub-woofer with the existing speakers. I mainly listen to blues and rock, anything from Clapton/Pick Floyd to Motorhead and Metallica but techno and rap will never be allowed near the thing. Any advice gratefully received re set up gratefully received.
