Hey, I'm new to Audi-sport.net so this is my first post. Thanks for taking the time to read this. Bought a B5 A4 2.8 Quattro 3 months ago. First Audi & I love it. Although thought I'd give the stereo a complete overhaul. Just bought; Alpine iDA-X001 iPod Head Unit. Alpine R-type 5.25 components (front - driven by HU) Alpine R-type 6.5 coaxials (rear - driven by HU) 2x Alpine R-type SWR 1022D Subs (500w rms 10" 2-ohm DVC) driven by; 2x In-Phase IPA-900 2 channel Amps. (350w x1 @4ohm Bridged) Lanzar Optikit0 Dual Amp Wiring Kit. Ok so, I'm gonna do everything myself as I cant afford to get it done professionally and I also like to get my hands dirty. Shouldn't have any problems with the head unit, rear speaker installation or Subs. However, have been reading through a couple of posts to find that I may have problems fitting the front components because of the depth. Has anyone done this already, and do they know if they will fit? I am mounting them on Autoleads 5.25" conversion plates. Also, the wiring......... Where is the best possible place to feed the power wire through the bulkhead from the battery? And then run it down to the boot? Its a Gauge 0 cable so its about 18mm thick. I want to run the RCA leads and speaker cable separate from the power cable so is there another route for these? And finally, can any one tell me where the best possible place to fix the ground wire in the boot is? It's the same size as the power cable. Thankyou. Any help would be much appreciated. Am now off to get the clutch fixed as it went after I ordered all this stuff!!! £650 expensive or cheap? I got quoted up to £1100!! Sods law eh?...... Thanks. Simon.
