Marc, I did indeed get the sub yesterday morning. I've played all day with it yesterday and have been doing at shit load of reading. My concern was that I installed the sub and went in town to see a customer. Ride was about 45 minutes, of course I blasted a couple of songs. When I got there I got out of the car and went and touch the sub and amp and they were both hot. The sub had a little smell (I guess this is normal?) So on I went searching and found shit on clipping. Boy have I read a lot the last 24 hours... Anyways, I found that I need to adjust my amp and this is how I did it: Downloaded a 0db 40hz test tone. Plugged my digital meter in the speaker leads of the amp. (I don't have an oscilloscope) Put volume at 26out of 35 and let her rip. BTW my system has 0 distortion at full blast volume (35) I adjusted to 34volts ac. (1200watts connected to 1ohm) anyways, that's what I read to do... Boy what a difference in sound...very clean! BUT Shit... no power!!!! It is so much lower in volume...I guess I need a stronger amp? Anyways I'm very happy with the sub...it sounds better than my Orion 12D I had. (Quality wise) Of course I'm comparing a 12year old sub to brand new!!! I will put pictures up with a small review soon. Thanks for everything but I may not be done buying shit from you. A happy Canadian (old man) customer... Now that you have a reference point try adjusting the gain by ear to a level just below the distortion point (unless you want it set differently). It may take a little bit of playing around with it on different songs to get it right, but most songs are not recorded at 0 db, they are usually at like -5 or -7. Just keep an eye on it and make sure it's not clipping/distorting. Impious beat me to it lol
