I went to one of the shops (mentioned on this forum in a negative way) and came away from there feeling that I'd like to have someone local wire up the components.
If there's someone here on the forum (who's on their own) who'll wire an Alpine receiver with two four inch speakers into the factory openings on the lower front dash on my 1993 Toyota extended cab pickup, with two additional five inch speakers into the rear side opening compartments, please e-mail me at email@example.com or PM me.
If you're very good at what you do, and are reasonably priced, I'd like to hear from you.
I can order the necessary components from Crutchfield needed for the job. I was told the job is fairly straight forward save for the rear speakers which would require a little additional work.
