2002 Vauxhall Astra Bass Upgrade
This is the second variant of LOUD BASS in this particular vehicle. We have replaced the 4 x 15″ subwoofers and amplifiers with a selection of 8 x 12″ Hertz SPL Show subwoofers and 2 x Hertz SPL Mono Amplifiers driving 4 subwoofers each. To go with this upgrade the front end is now powered by a Hertz SPL 2 channel amplifier.
