I have the 9813 model head unit it has a time delay feature , easy to set by plugging in your speaker to listening position.
Alpine web site can give you the settings for your TD .
The Bass Focus is a separate feature but when adjusted it affects the time delay.
I would like to use the Bass Focus but I do not understand the instructions completely.
Is any one else here using this feature and how is it set?//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif
