Well i got the car back yesterday after a week in the workshop having a full audio and security upgrade, the factory fitted immobiliser has now been bypassed for a Clifford high end security system. The audio upgrade is amazing when you open the door everything looks stock and you'd never guess they was a amp,sub,Alpine head unit DAB radio and Bluetooyh compat,new door and rear speaker upgrade,used all oem speaker covers too which is a nice thing. The amp is seated in the space saver wheel up front and 9 inch sub under the glove box okay i've lost the glove box space but this is so worth it, the quality of sound now is just bliss! The company who did the install was Source audio in Sheffield the man to speak to is Paul he's such a geek when it comes to audio and this was not the first 993 he'd worked on.. Summer vibes!!!! 8)
