tweaking Alpine headunit
to set up the parametric eg, you will need access to an rta for a few hours at least. some will tell you that you can use a crap shack db meter and paper, but there are too many problems with that route. the best way is to go a shop with serious experience in sq competition and who sell alpines. on the west coast, i suggest speakerworks in orange county, ca. jps
