Servus people…. I know that this is a Car Hifi forum, but I’m still interested in which dB values you can achieve with your equipment. Just for the sake of interest. Which subs, how many and how loud?! I am doing audio with my 15th spinner with the Helix 1000.2 ne 146.2 with approx. 1.2 KW rms. With the DD Z2 I get to 149,5 dB at approx. 2.5 – 2.7 KW rms. So let’s go… I want to see values!!!!!!!!! Mfg Stocki
