I already have fitted a Sony CDX-DAB6650i with Dab external aerial connected to the standard Bose amp and speakers and sub via a modified phono leads with 18uF caps in to stop the mute thump , but fed up with the harsh poor sound quality from the nokia tweeters and mediocre tupperware style subwoofer. Due to usual time and money restraints (still not much better) and with a family nothing further has been done. I have so far, a KENWOOD KAC-846 4-Channel Power Amplifier (4 x75w RMS) to replace the Bose unit in the rear driving the main 4 speakers and was thinking about putting it under the smaller lift up storage hatch in the middle of the boot cutting out any molded bits to suit amp. I will also be fitting a Pioneer GM2000 (200w) to drive the the sub or subs this amp will go down to 2 ohm if need be. Speakers will be 2 pairs Mac Audio custom fit (the old school ones) P1.F and A1.F with separate tweeters and 165mm bass units used in many off my cars so far (Cavalier Calibra 405 and now a proper car) Just a bit undecided what to do about a sub as my 12 inch Celestion AD12 works well in the home cinema so that will stay there. I also made a smaller sub with 2 American (i forget the make) 8 inch drivers with magnets nearly as large on the back, in an approx 12x12x20 inch box with the first sub working as an enclosed sub and the other on top so it was looking at an infanent baffle, it was kind of an experiment to get more usable boot space so i may use this to start with but looking to hide it either an 8 inch either side with old sub and amp removed and do something with spare wheel well with the tyre still in place and port it. I am also looking to integrate my itunes library into the car, i tried using the iphone and the A to D converter is very poor so possibly trying to use it as just a remote to control the itunes on a Mac/PC/Linux/apple tv but not sure yet and also funds depending. Also my son on long journeys likes to watch films (keeps him occupied and quiet with headphones on) so may do a headrest monitor as i picked up a couple cheap and run them via my wife's iphone with video/audio out. Any suggestions or ideas i would be grateful. Wiring is not a problem as im an audio engineer, but i keep looking at it and cant decide on the sub issue. I will try and take photo's as i go in case it helps anyone else.
