2002 Vauxhall Astra Audio Upgrade

A custom audio upgrade, concentrating on a heavy heavy bass sound.  4x 15″ Hertz Hi-Energy subwoofers, each powered from a Hertz HDP1 mono amplifier.  Hertz SPL Show 8″ mids and SPL Show tweeters mounted into each door to give an extremely loud but clear sound, which are powered from the remaining amp, a Hertz HDP4.

When I arrived back home after my short trip from Source to Donny today, I thought a short thank you email was in order. When I first sat behind the wheel and heard what a difference your adjustments had made, I was very pleased. I put Pink Floyds’ “Dark Side Of The Moon” in and set off for home. When I pulled onto my drive, I couldn’t get out of the car for 10 minutes because the CD hadn’t finished. It was stunning ! All the meticulous work you put into my install came together today and exceeded all my expectations. The sound stage is now immense, fills the front of the car and is fully balanced to my seating position. A great many thanks to you and all the team at Source Sounds, I wish you every success in the future.

I just wanted to say a massive thank you to yourself and your team on the fantastic job you did on my BMW 1 series. Initially I was stunned by what you guys had managed to achieve using a standard head unit. The sound quality is awesome, I am hearing things I have never heard in tracks I listen to time and time again. Now that I’ve had some quality listening time the system continues to only impress me. The install of the speakers and amplifier is exceptional to say the least. In line with the high level of standards you guys install to and combining this with the excellent customer service Source Sounds provide, I can only applaud you for the operation you guys have there. Thanks again (from a very happy customer)
