Can you give me any guidance as to what I should expect to pay? I live in the Boston area (Cambridge actually), and might be giving Custom Auto Radio a call. I have a '96 Miata, with a head unit that has Aux inputs in the top DIN slot. What I'll need to have done is have that moved to the bottom DIN slot, and have the Empeg installed in the top slot, using the Aux In's on my head unit. The head unit was originally installed by Best Buy at the time of purchase.. I think it was in the $50-$75 range? My memory is crap. I suppose what I'm asking is if I should expect one of these custom shops to be significantly more expensive.

Thanks,
Jay
