At last! I am getting rid of the Concert system. After weeks of research, reading forum contributions and phoning round ICE dealers, I have finally found my new system. It's an Alpine HU, with matching CD-changer. (Andymac, if I remember rightly, yours is an Alpine, isn't it?). I've gone for the 9823 model,, with black housing & red display, so it's about as compatible with the A4 fascia as I can get. I'm keeping the active rear speakers, feeding them from the pre-outs on the new HU. I'm also hoping to fit an extra pair of speakers in the rear doors, fed from the otherwise unused rear speaker outs on the new HU. Providing there's space in the door frame, they'll be mounted low down in the recessed section below the window winder. I thought either 4-inch round or 4-inch by 6-inch ovals will fit just nicely. They'll provide just the right amount of "in-fill" sound, just behind my head.
The dealer I'm using had all parts of the system in stock, ready to fit, except the HU itself. So I have to wait until they can get it in & I'm next in town. I've got it booked in for two weeks today, which is ideal. It means that by the time I pay for it, my credit card will have rolled over into a new month. Plus, I also get it installed the week before we go on a touring holiday in Scotland.
I am soooooo looking forward to getting it installed
