I thought Caraudio.com wisdom was I should have done everything myself? Granted if a shop has a scope, yes! I will call Custom Sounds and see what they charge for amp gain tuning if they use a scope. Objective is best, then I can get in the DSP and play from there!Your best bet would be to find a shop that can set all your gains for you, be it with an O scope or an SMD DD1. That way you know when your system clips and you don't ruin any more speakers. After shop sets everything up for you DON"T touch any gains.
