i want to install my alpine ivad901 and the kca-420i (ipod adapter) into my 2001 540i w/ dsp. all these things are in my 84 325e and need to be transferred over. they audio shop is asking ~ $300 and if i want to try the steering wheel control adapter, that's another $120 but no guarantee it would work.
they also told me that if i want to include my subs, i would need to purchase 4 crossovers and the grand total would be $800. do either of these quotes sounds right or should i try to work them down some more?
thanks for any help that any of you can offer, i want to install these things by the week's end, but i'm just not sure.
