So recently came into funds to allow me to carry out my first proper install in my 1999 Audi S3, currently standard sound system with Non BOSE and concert, CD multi Changer in the boot & The VW ipod kit. Not The biggest I.C.E Expert although know bit and bobs being a VW Techi. Looking to get stuck into it on saturday but just looking for a few pointers from the experts. So purchased so far: Vibe Black Air 12" Sub+AMP 1600W 4" FLI Intergrator Front speakers 6.5" FLI Intergrator Rear Speakers 1" FLI Tweeters Pioneer DEH-P5100UB Headunit Ipod connector 14M Stinger speaker cable 14AWG Vibe 8AWG Amp wiring kit 2 x PHONOCAR 2-WAY CROSSOVERS Facia Adaptor So Any pointers on things to watch out for when installing and anything i have missed?? pictures will go up on saturday on how the install goes if anyone interested. Shall be going over the S3 wiring diagrams for the original HU tomorrow so i can get a good idea of whats going on!
