After bumpin' for like 45-50 mins at max they start to smell tangy but you have to put your nose to the port to smell this...I set the Gains with a DDM and i used a 50hz -3db tone. I have a Alpine MRP-M1000 Amp and (2) Type R's Wired to 2 ohms. I set the volt to 46.7 and the chart said to set it to 46.9, I have the Bass boost way down its not all the down but almost.
