Wow... I didn't realise such a thing was available to tune the sound of your ICE system now??
Things have certainly moved on a lot from the days of throwing a load of money at Alpine or Kenwood and hoping for the best... Come to think of it, it's nice to see the subject of ICE being discussed again. After the whole "Max Power" era it got a little bit stigmatised in the UK IMO and people moved onto more Trackdays & driving the cars, not just sitting in Maccie D's car-park listening to your Choons!
