sub not switching on


I have a 10 in def tech sub as a second sub. I use this only for 40 to 20 hz and the paradyne for 100 to 20. The Def Tech is not always turning on... I have is on a 30' rca cable run...any suggestions? Thanks

Thanks for the suggestions. The problem is...I only like the def tech on the lower freq and I don't think that it has an always on. I may consider opeing it up and over-riding the switch...but I am very lightly skilled below 120 volts.
Try setting the level controls on both your subs higher, and the level control on your processor lower. This worked for me when I had the same problem with a Sunfire sub...
The sub is not getting a constant signal if it is set for such low frequencies. You may have use the always on power switch if it has one.
