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.

Absolutely brilliant, outstanding service from advice on which alarm to have, very professional install and great introduction to the system when it’s fitted. I’d recommend these to anyone. Well done!

I have had several products installed by Source and have always been happy with their service. They are a great bunch of guys who take the time to understand your needs and provide professional advice. No pushy sales just pure knowledge and friendly advice. I would not trust anyone else with my car audio and security.

A rare treat to experience excellent customer service, real expert and knowledgeable advice, enthusiasm and on-going support. Nothing is too much trouble for Paul and the team at Source Sounds. I wouldn’t even consider going anywhere else!
