looking to a Digital eq unit. must have a hide-a-way brain unit, then a very slim 1-2 inch deep and no bigger then 1 din size face plate. the alpine ERA-G320 is a nice unit thats almost exactly what im looking for. i do not want any pioneer units, they are very low output voltage. not sure if any other companies make units like this. unit doesnt have to have a sub out, but probably will. also unit should have at least 10 bands of eq. and a good preamp voltage out of at least 4 volts.
