I have been wondering if it's possible to upgrade to the DSP sound system as a d.i.y. job. There are some cables fixed down under the rear parcel shelf, but I don't know if they are speaker cables. The dealers that I have spoken to about this have said leave well alone.
I assume the Becker DSP amp just plugs in in place of the original amp, assuming of course that I could get hold of one in the first place.
It's just that I hate those empty speaker housings.
How difficult could it be? Of course, if the front console has to be stripped out..... eek!
