I am new to the site, and just wanted to give my thanks to Andy Mac and C following a SS install recently in my A3. Following a lot of research I decided to give Andy a shout at the beginning of the month for more information on the SS. Firstly he gave excellent advice on parts and prices, and a decent timeframe to get things built (from first contact install was 2 weeks later). He let me decide exactly what I needed - no pressure, and gave impartial information on what he could do for me.
On the day (following decent directions to his place) Andy and C were very hospitable and Andy cracked on with the job at hand straight away. The job took about 4 hours and was a better install than you would get from a specialist, as he took his time and had his technique down - no joke!
The sub enclosure is a proper professional job (excellent finish and bomb-proof build) and the sound quality has been a revelation. Once that bass was taken away from the cabin speakers they sounded so much clearer and picked up a lot more detail from all types of recordings. Obviously you can't compare the sub to a massive boot filler, but if you're after an upgrade that will provide excellent sound across all frequencies then this is the one to go for. The bass is now very tight and punchy - goes much deeper and is a lot louder.
Once again, I can't recommend Andy and his SS enough. If he's got the time and you want one, just do it. You wont regret it! In my opinion, for the money it's the best upgrade you can get from a standard setup.
