I think i have symphony 1 headunit in my 1999 A4? I don't really want to spoil the look of the dash so was thinking of connecting it to my pioneer DEQ P800 DSP (which has a single din face only 1 inch deep i can mount somewhere) to then goe off to the amps i'll install to power all speakers in the car. I did this in my previous golf as it had built in sat nav so i had no choice. I have a top of the range Pioneer MP3 OEL head unit with built in DSP as well, but like i mentioned, i don't want to spoil the dash, plus as the symphony is double din, it would be a sod to do? Anyone got any thoughts or suggestions? Basically i am worried i'll do all this and have [censored] quality, i have found the hidden graphic eq in the symphony, but does it make much difference? HELP PLEASE!!
