Understood Joe and thank you for the response it's much appreciated.
Box tuning is 33hz, I've used the DD-1 to tune the amp however I know this obviously doesn't cover everything as you mentioned.
Additionally, in one of the videos of Steve I watched recently he was going over the importance of why you need a quality LOC, which I'm using an AudioControl LC2iPro, which I tapped some speaker outputs as my inputs into the LOC. Steve mentioned that I believe (I could have manterrupted) that most amps "like" 5volts in from a LOC. I used a multi-meter to adjust gain on the LOC and was able to get 5volts finally right on the mark. Did I understand this correctly?
Thanks again for any help in advance.
